Hi Götz,
We were planning to upgrade 0.7 version 0.8, that is why we didn’t order any of them. Just not fully ready yet.

ANY NEWS?
Hi,
I was wondering if the mcHF 0.6 components kit has the SMD components soldered on already. I assume (and hope) the answer is no, so that I will get to do some SMD soldering!
Thanks,
-Jonathan, KM4CFT
I have the same question .. if I buy the v0.6 UI and RF kit will the smd be soldered on already?
I don’t have the gear or the eyes (due to age) to want to solder smd.
Thanks

Hello Jason,
Thanks for your interest in the project! Yes, all the kits we sell now are with SMD parts pre-installed.

Hi,
Is it possible for me to order the mcHF 0.7 kit without the SMD components soldered on?
I am planning on doing this as a project, and I would like to use this to get some practice doing SMD soldering, and there doesn’t seem to be a configuration to do that.
Thanks,

Hi, I just received my v0.6 boards and components last week, and have begun assembly of the UI board. I am wondering about the recommended LCD, where do I source one? What are the options

I just found out that to assemble the kit, it will be necessary to wind numerous coils for the RF section. I am afraid that the task would be much to tedious for my dexterity and vision at my tinder age of 76 years. 🙁
Please cancel my order and issue a refund to paypal.
Thank you!

hi, M.D.
I just stumbled across this project and ordered myself a 0.7 kit to build. If not too late, and convenient for you, you’re welcome to mail / post your coils to me and I’ll wind them and return them to you free of charge. You can find my info at qrz if you’re interested in contacting me.

I couldn’t pass on the sale price, and just bought a complete kit. Can I use my present supply of lead solder to assemble it? (Been around electronics for over 60 years and have yet to try the ROHS variety 😉 .)
Hello, my call sign is YO2AP, name is Giani Miroiu, currently located in Hengelo, The Netherlands, and I need some clarifications, as I am quite interested about your product.
– what is the real confirmed receiving range of the transceiver ? it is advertised it starts only from 2 MHz and up, but how does 160 m band is covered then ? Does it mean the AM band is not covered ?
Also, is there a link to some extended specs of the receiver ?
– what is the transmit range ? is it blocked outside HAMs bands ?
– is this transceiver different from SW point of view regarding HW versions ? I see v 06 and v 07 are different hardware versions, will any future SW upgrade covering both versions or the updates will be separate ?
– I see that some kits are incomplete (no final FETs delivered) … does it mean I have to purchase them separately ?
– I see a Chinese version for sale online, will your SW upgrades cover that HW version as well ?
I fond really intriguing your design, big up for the efforts. I will follow your latest updates for version 8, and if you have a complete package for sale I will purchase it from you, of course.
Some remarks about your website which could be beneficial:
– I do not see clearly what are the differences between your HW and SW releases
– some of the product specs can be expanded
– hard to find info following thread-based replies (WordPress feature I suppose …)
Otherwise, keep up, really cool design ! Respect !
My best regards, Giani
73 de YO2AP
Hi Giani,
Thanks for your interest and comment! But first, this is not a product, but a project.
– receiving range is limited by the SI570. Latest releases on GitHub support another chip that can go lower than 2 Mhz and upto 50 Mhz, instead of 31 Mhz the SI570 provides. I guess 160m was added because of that (and still need to mod the filters). I did some measurements into the receiver, just check my old blog posts pls
– As the firmware is open source, you can make it TX anywhere(limiting by the LPFs)
– No changes on the RF part between 0.6 and 0.7 Current Github firmware fully supports
the 0.6 and 0.7
– Not supplying the MOSFETs as we can’t find bulk supplier for those
– Chinese clones probably use standard firmware, really not sure, sorry
About the website sorry, this is the best a can do as a hobby web developer. Really don’t have much
time to update it, most stuff is here for at least four years.
73!
Really appreciate your answer and efforts to keep this project running.
I’ll come soon with a reply !
All my best wishes !

I think your doing great!

I’m in a quandary: should I wait for 0.8 or take advantage of the lowered price on 0.7?
Are there more details available (besides touchscreen and changes to UI board) on the differences?
And I’d love to see the photo on the home page, mentioned in the 0.8 post…
Thanks!
Hello,
At first we plan to offer just the UI board for 0.8, without changes to Logic and RF, as it is simply
too many things to test in so little time. Then slowly switch to new boards altogether. So it is up
to you, but 0.8 is not that close. I wish it was.
73
After a lot of searching, I am still confused. Are the smd parts already soldered to the boards?
I am going to connect the transceiver to my computer for digital modes. Will it interface with USB only, or will I have to build audio cables also.
A suggestion. You need to offer a “Black Box” version of the transceiver. It would be for connecting to a computer ONLY. No knobs, audio circuits, display, buttons, etc. Power, antenna, and USB connectors are all that would be needed on the box. Should be a little cheaper.
Hey, such black boxes already exist. They have a huge FPGA and ADC or two that sample everything from DC-80 Mhz. You can run
one gazillion receivers on the PC in parallel and the sky is the limit. No point to use the simplified mcHF design for that.
“Hey, such black boxes already exist. They have a huge FPGA and ADC or two that sample everything from DC-80 Mhz.”
Thanks! Where can I find one of these?
What about the USB question? Will I be able to operate the transceiver using USB only? Or will I have to build audio cables?
Dear M0NKA, can you ship to russia?
Hello,

Hi
What LCD controller type is used on the 0.7 version of the kit? Is it the ILI9325 or SSD1289?
Am asking since the v0.7 excel BOM does not specify the controller type on the HY32D LCD.
The LCD supplier (hotmcu.com) has two versions of the HY32D LCD with different controllers
(ILI9325 & SSD1289).
Thanks.
Hi,
I am not sure really, but seems to be supported by the current firmware. If you really need it, i can
check the bootup screen and let you know. Also there is no way for the BOM to list this, usually when
creating components for the schematics library you just list name, not details of internal components.
73
Hi
Regarding: If you really need it, i can check the bootup screen and let you know.
– Yes, pls check and advise what controller is supported by the f/w for the HY32D LCD.
Is it the ILI9325 or SSD1289 controller. Or both??
Also a link to the actual LCD part (as used on the v0.7 hardware) to the vendor website will be very helpful.
Thanks,
Hey!
Controller is ILI9328 and LCD link is here:
http://www.hotmcu.com/32-touch-screen-tft-lcd-with-16-bit-parallel-interface-p-36.html
73!
Hello
Is the ILI9328 confirmed from the v0.7 radio boot screen?
Can you double check the posted link cos it says that the LCD controller is a SSD1289.
Thanks,
This is what the screen shows. For more details maybe needs a debug build of the firmware and printing
more info, but right now i don’t have my proto wired for that, sorry.

Hi Jim,
We charge 17 something GBP, but it seems the post office price lately is about 21 something.

Quite glad on finding the mcHF source (after seeing the clones). Is there an “operator manual” for the v0.7 somewhere? I looked in the “mcHF_rev_0.7.zip” file, but nothing seen there for the Op Manual. Maybe I missed seeing the link or something. After seeing some of the YouTube videos of the v0.6 units (all clones I think), I believe the v0.7 unit’s operation should be close to intuitive. I do plan on placing an order for the full kit from here over the weekend.
Hello,
This would require proper description of the firmware features and menus, and unfortunately this is beyond our control right now. We just support the small scale kits manufacturing. Maybe in near future, who know.

Sorry if this is repetition, but I see that an email sent by someone only yesterday appears at the top of this list while mine, sent about a week ago when you were away, was “awaiting moderation” and is nowhere to be seen. I asked if any more assembled version 0.6 boards would be made available, since I see that I’m not alone in preferring that configuration for the sake of portability. It does seem a great shame that the needs of those who like portable operation have been rather overlooked in this latest version, particularly since it was only ten days or so ago that I discovered this set fully built from China. But subsequently, your website and “the Devil is in the detail” remarks caught my eye, thank goodness!
Hi Martin,
Chris as already answered to this question : ther is no more version 0.6 available

Christophe, F4ANH
Dear Christophe
Very many thanks for your kind reply. I am sorry to learn that is so. I am also sorry to see how “newbies” are both replied to and have to struggle to understand things on this incredibly inward looking website, apparently structured for the benefit of only true initiates. A great pity, since the idea is probably of much wider appeal and I felt a good deal of sympathy for someone who had had his idea ripped off by the Chinese. Sadly, it looks as if they will be getting my custom, no matter how much I would have preferred it to be otherwise.
Kind regards
Martin Amstell

Dear Christophe
No, I hadn’t seen that this point was covered anywhere on this deeply confusing site, despite looking. But it has just occurred to me that it’s owner must have encountered my original post and “moderated” it to the dustbin before ignoring completely my second. Only days ago, I stumbled upon the Chinese clone of this marvellous set on eham.net and got all excited, eventually tracking this site down, but being ignored until your kind intervention. Still, it’s reassuring to know that someone with a Bulgarian surname is acquainted with English expressions like “The Devil is in the detail.” Let’s hope he also becomes aware of another, that “Manners maketh man”.
Kind regards
Martin
Bonjour Martin,
Je vous répond en Français car mon Anglais est catastrophique :
Chris ne peut malheureusement pas répondre à tout le monde, son YL lui donne un précieux coup de main, mais vu le nombre croissant de demandes …
Avant que mon premier message ne soit validé il c’est passé une bonne semaine, cela ne m’a pas dérangé, rappelons nous la rapidité des premières liaisons “Packet-Radio” en AX25 : c’était lent 😉
Personnellement, coté financier je vais attendre avant de pouvoir commander un kit complet, et ce ne sera pas la version chinoise pour plusieurs motifs :
-version chinoise = v0.6 ou antérieur
– version chinoise de qualité moyenne à médiocre sur certains composants, dont ceux des filtres, ce qui est un peu crucial pour le fonctionnement de ce TRX
– Chris M0NKA, et un certain nombre d’OM ont mis de leurs temps, de leurs moyens, pour réaliser un appareil magnifique, en constante évolution.
– les Chinois on copiés ce travail et le commercialisent sans autorisations ni indemnités. Moi je ne cautionne pas cela.
la version V0.7 est certe plus grande et moins “Portable-compliant” mais elle est vouée à évoluer.
as-tu regardé le nombre de composants qui compose ce TRX ? il y a beaucoup de travail, j’ai récemment acheté juste les PCB de la V0.7, pensant pouvoir trouver tous les composants moi même, ce n’est pas si simple, cela représente des heures voir des jours de travails pour préparer une liste pour commander le matériel. Chris l’a fait, et ça mérite le respect.
Et coté prix, je trouve cela plus que correct. les chinois sont dans la même fourchette de prix, mais pour une qualité largement inférieur.
Je ne vois pas le rapport entre l’origine d’un nom “bulgare” et la connaissance de l’Anglais ? les radioamateurs ne devraient-ils pas s’affranchir de ce type d’étiquette ?
Cordialement,
73
Christophe, F4ANH
Version of my answer translated by google:
Hello Martin,
I answer you in French because my English is catastrophic:
Chris can not answer everyone, his YL gives him a helping hand, but given the growing number of requests …
Before my first message was validated it was a good week, it did not bother me, remember the speed of the first links “Packet-Radio” in AX25: it was slow;)
Personally, financial side I will wait before I can order a complete kit, and it will not be the Chinese version for several reasons:
-Chinese version = v0.6 or earlier
– Chinese version of average to poor quality on some components, including those of filters, which is a little crucial for the operation of this TRX
– Chris M0NKA, and a number of OM have put their time, their means, to achieve a beautiful device, constantly evolving.
– The Chinese copy this work and market it without authorization or compensation. I do not endorse that.
Built V0.7 is certainly larger and less “portable-compliant” but it is doomed to evolve.
have you looked at the number of components that make up this TRX? there is a lot of work, I recently bought just the V0.7 PCB, thinking I can find all the components myself, it is not so simple, it represents hours to see days of work to prepare a list to order the material. Chris did it, and it deserves respect.
And quoted price, I find it more than correct. the Chinese are in the same price range, but for a much lower quality.
I do not see the connection between the origin of a “Bulgarian” surname and the knowledge of English? should not ham radio operators get rid of this type of tag?
Regards,
73
Christophe, F4ANH
Dear Christophe
I’m 73 and used to build crystal sets and simple transistor sets in my youth (OC70s?). I fantasised about becoming a ham, but work prevented that and, on retiring, learned about QRP, which appealed to my as-small-as-possible attitude. Product reviews of the Chinese clones on eham.net and YouTube got me really excited just days ago, but I was saddened to learn that they were ripped off from this project, so made efforts to find out about the mcHF. But it was hard going! Most sites, including this one, seemed to be about people intensely talking to one another about abstruse matters with no way in for a newbie. Being confronted by blogs, without guides to more basic things, seemed ultra confusing. Then, bliss, I saw “The Devil is in the detail” and emailed the owner, but failed to connect. Hence my first post, and then second, as described. Since my fantasies extend only to portable operation, I was keen on the version 0.6, as featured in the clones, and certainly saw nothing saying these boards were discontinued, despite version 0.7 having arrived. So I was particularly disappointed to be ignored (twice) as others who wrote were also ignored. This seems to me to be unpardonable, particularly in view of the site’s confusing organisation. Since the owner appeared to have a Bulgarian name (not that I have the slightest thing against Bulgarians or any other nationalities) and his syntax seemed a little uncertain in places, I ventured to suppose he might not be familiar with an particular English expression, which he might benefit from knowing. I’m sorry you clearly think that this was a cheap shot. If the portable version is no longer available, and particularly if serious enquiries are ignored, I won’t be troubling this site again. But you should appreciate that the whole approach here does seem to be horribly unwelcoming to newcomers.
With kind regards
Martin Amstell
PS Please accept my apologies for the following Google translation. In English amateur radio operators are called “hams”, but this looks quite funny in French!
Cher Christophe
J’ai 73 ans et j’ai l’habitude de construire des sets de cristal et de simples transistors dans ma jeunesse (OC70s?). J’ai fantasmé sur le fait de devenir un jambon, mais le travail l’a empêché et, en prenant sa retraite, j’ai appris sur QRP, qui a fait appel à mon attitude aussi petite que possible. Les commentaires sur les clones chinois sur eham.net et sur YouTube m’ont vraiment enthousiasmé il y a quelques jours, mais j’ai été attristé d’apprendre qu’ils ont été détournés de ce projet, alors j’ai fait des efforts pour en savoir plus sur la mcHF. Mais c’était dur! La plupart des sites, y compris celui-ci, semblaient concerner des gens qui se parlaient intensément à propos de sujets abscons, sans aucun moyen pour un novice. Être confronté à des blogs, sans guides pour des choses plus élémentaires, semblait ultra confus. Puis, le bonheur, j’ai vu “Le diable est dans les détails” et a envoyé un courriel au propriétaire, mais n’a pas réussi à se connecter. D’où mon premier message, puis deuxième, comme décrit. Étant donné que mes fantasmes ne s’étendent qu’à l’utilisation portable, je tenais à la version 0.6, comme dans les clones, et je n’ai certainement rien vu qui dise que ces cartes avaient été abandonnées, malgré l’arrivée de la version 0.7. J’ai donc été particulièrement déçu d’être ignoré (deux fois) comme d’autres qui ont écrit ont également été ignorés. Cela me semble impardonnable, notamment au vu de l’organisation confuse du site. Puisque le propriétaire semblait avoir un nom bulgare (pas que je n’aie la moindre chose contre les Bulgares ou d’autres nationalités) et que sa syntaxe semblait un peu incertaine par endroits, j’ai osé supposer qu’il ne connaissait peut-être pas une expression anglaise particulière, il pourrait bénéficier de savoir. Je suis désolé que vous pensiez clairement que c’était un coup bas. Si la version portable n’est plus disponible, et en particulier si les demandes sérieuses sont ignorées, je ne vais pas déranger à nouveau ce site. Mais vous devriez comprendre que toute l’approche ici semble horriblement peu accueillante pour les nouveaux arrivants.
Cordialement
Martin Amstell

Hey Martin,
Apologies for not replaying to you! I have been very busy with organizing stable production and supply of kits in the last month or two, also doing small updates and improvements. I have left my wife Lucy to handle all e-mails, while me only handling specific technical ones. Really didn’t have much time lately for social media drama, haven’t been on Twitter for a long time.
73, Chris

Maestro
Lovely to hear from you, at last! “Social media drama”? Me neither! What is Twitter? Ditto Facebook? I’m 73 after all.
I was genuinely sorry to hear that what must have been years of grinding endeavour on your part were so mercilessly ripped off by the Chinese. I was also genuinely sorry to hear that version 0.6 is no longer an option, tailor made for portable operation. But, despite all this, and the no doubt correct warnings about component quality in your “Devil” piece, I’ve had no alternative but to order the latest Risen (Recent) model RS-928 for when I eventually qualify for my “ticket”.
But I’ll keep a weather eye out for developments here, in case you decide a portable version is worth resurrecting and, in the meantime, wish you every success in your future efforts.
Kind regards
Martin Amstell

Hi Chris,
firstly, many thanks for your effort and great work. I am about to order two pcs of the ver 0.7 full kit, for me and my colleague. But I want them with enclosures. What do you think – to order them now and enclosures later, or to wait for some days or weeks and order them altogether?
73! de Milan OK1FMF
Hello Chris, Just started debugging my V0.6 kit. Loaded with latest version from DF8OE. I tried to get help via the Yahoo M0NKA mcHF site but have not had a response in the 3 days. Upon power up, i get the version splash screen just fine, Green on solid, Red off, get noise on the speaker with 50 ohm antenna dummy load. It never proceeds to the application screen, just stays stuck on the version splash screen.
I’ve tried removing 0 ohm jumpers for the screen as presented in yahoo group, but nothing seems to work. So…. how does one get help with problems like this? Is there a master trouble shooting guide I’m missing somewhere? Thanks for the help… ..Lynn.. W8LFM
Really like the look of your system, do you think you will ever sell fully assembled units for an additional cost? I know my limits.
In case anyone is wondering about shipping times, my full kit shipped out on 5 January, and arrived 19 January in Massachusetts USA. Two weeks including customs time, etc. Not bad really. But it seemed longer 🙂

My v0.7 kit is up and running 🙂 Just one button was faulty from the outset – another ordered from Farnell. U3 and U4 (Voltage regs) on the RF board run quite warm…? Just need a case for it now!
73 – Rob G0MOH
Hi Rob,
Sorry to hear that. Do you need replacement button ? Drop me a mail if needed.
73
No problem Chris, I have 2 spare buttons coming from Farnell.
Next thing will be the case. I wonder would it be worth offering the kit WITH a case, rather than trying to buy it separately? I’m sure there will be people out there who have bought the case, and don’t even have the v0.7 kit yet HI.
73 – Rob G0MOH
That’s what I did. The cases were in stock, so I ordered. Then I waited for parts, checking back several times a day each day until they were in stock. I ordered the moment stock was available. Now if only I knew where they were. 🙂
Ordering and shipment are half the battle. USPS tracking is abysmal. The case was processed through New York 5 days ago at 4 in the morning – and despite signing up for status updates, that status has not progressed, and no updates have been provided. The parts kit has been in “origin post is preparing shipment” status for a few days now.
Hi Jim,
Sorry about that. It is just temporary high demand due to the new revision, it will go down soon.
73
Not your fault, Chris. You are doing the best you can to support such high demand! Thanks for your tireless efforts.
The recent huge snowstorm “bomb cyclone” that hit the northeast US is probably why it took 6 days for my case order to move from Kennedy airport in NY to a distribution center in Queens, NY. Wow!
Hi Chris. Just orderd v07 but in my eagerness to order forgot to change postage to Uk cost. Know your busy but hope you can watch for that and deal. Malk G4IHZ
Hi Malk,
Thanks for your continued support! Just did the partial refund, it will take few days to show up, i think.
73!
Yes! I was able to order a v0.7 today! Looking forward to ordering a chassis!
I’m one of the lucky ones, today I got a kit. Very very happy! Now I have to check back each day for the availability of a case!!
Arrived this morning!
Checked the page again today – lo and behold kits are again available and it seems I successfully ordered one. Thanks Chris for your continuing efforts and for putting the kits together. I’m looking forward to the project and getting a case soon too!
Best 73s,

Given up on actually obtaining a kit.
Confused. by the site and the I’ve been assuming there are no kits to purchase currently. (Below reply)
Can you clarify if the kits are actually available and can be ordered, or are you still waiting to collate kits for purchase as of 28/12/17
Many thanks.
Robert Lang (GW0FJV)
(Sorry, the Stock/No Stock label on the Order page is not linked to the PayPal quantity variable, this is
the problem. So i have to change it manually, but sometimes it takes me some time.)
Hi Robert,
Sorry, i have finished the LCDs right now. Waiting for a delivery, when i have it, i will put kits
for sale. I guess there is a huge number of people who were waiting for kits and whatever i list it
ends up finished quickly. I am sure in a month time max things will be back to normal.
73!
Hi, half a year trying to catch “in stock” position… annoying.
Any idea how to catch and order kit? or even assembled if its in options
Chris,
any rough prediction when the case (enclosure) might be available? Or do I have to buy it somewhere else and you only publish the 3D files? I was lucky enough to snatch one of the full 0.7 kits, and it would look even better with some sheet metal draping …
73, Ulrich
I am in the same situation. I am starting to build the kit but have no clue what I am going to do for an enclosure yet. If I could order just the enclosure from you I certainly would prefer that over building one from scratch.
Best regards for the holiday season.

Order page continually tells me v7 complete are now in stock but paypal will not accept payment with error “the v7 complete is out of stock”.
Hi,

the problem. So i have to change it manually, but sometimes it takes me some time.

m0nka,
I had to purchase a clone because you cannot supply the demand and time is of the essence. I very much appreciate your engineering but not your marketing. I have my specialties, also, and can empathize with your pluses being overshadowed by your minuses. I am critical of myself no less than I am of you. I am, also, very disappointed as I have waited for a year now but have found the full kit unavailable each time I have checked. Bad timing on my part. You do know that some of us can program the radio so that bare hardware is better than no hardware. Good job, otherwise. Herm, KG7WMZ
Hi Herm,
I am sorry to hear you are disappointed, i am really trying my best here. I wish you all the best in your
future endeavors and i am sure you will still contribute to the project in other ways, maybe bug fixes to the
code or hardware mods. But in all fairness, i had constant stock of full kits during 2017, it is just last
2-3 months i had sketchy availability, due to the complete redesign to v 0.7.
73!
If I put 427VGT instead of 407VGT, will the device work?
Hi Segrus,
I’m not totaly sure but the answer is NO , depend on the memory mapping
The memory remap is not the same : view the STM32F4 datasheet page 71 : http://www.st.com/resource/en/reference_manual/dm00031020.pdf
73, and Happy new year

Chris: When do you expect the next batch of mcHF v 0.7 Full Kit to be ready?
Ted WD4CAV
I ordered! Cool!
Chris, can you tell me what sort of kits you will make available for rev 0.y? Will there be one that includes the case? Will there be a version with most smd parts pre-installed?
Great job, this rig is awesome!
Sorry.. 0.7 (not 0.y).
Hi Jim,
The full kit will be the only one i will sell from now on. All SMD parts installed, only through hole left for the user for
post assembly. Case i can not realistically ship with the kit as the package is getting too heavy and expensive to post. So
it will be separate item on my Order page. I also have some delay with last components for the case, not sure if Fedex lost
my last shipment, trying to sort it out.
73!
Chris,
when will the enclosure (case) be available?
73, Ulrich, N2DE
Hi Ulrich,
I hope in few days, but lets see.
73
Hello! When would you have some mcHF v 0.7 Components Kits?
Hello Gerhard,
It is very difficult to make, also very expensive. Don’t plan making any for the moment, sorry.
73
Hello! Glad to see that the mini kits are available for order. Two questions:
1) Did I miss the full kit sale, or have you not put those up yet?
2) Does the Mini Kit have an installed CPU? I remember you saying that it would, but the description says “blank PCBs”
Hi,
1. Not yet, will try to list later
2. Blank boards means just the PCBs, no components (except the LCD).
73
Chris: Please remove my email address from my request below and delete this request. Thanks. Ted Salmon WD4CAV
Done, 73!
Hello Chris,
I really want to replace the Chinese clone (RS918 by Risen) with the “real thing”. Can you please give me a rough estimate when the pre-assembled full kit (SMD components installed) might be available again?
73, Ulrich, N2DE (DJ5US)
Hi Ulrich,
Thanks for your support! I will have some full kits in a day or two. I have a lot of stock,
but this time i install and program the CPU, so I will be bit slower than before. But i am
trying my best.
73!
Hi Chris
That’s great to hear. I am also very interested in buying a full mcHF kit and would much rather purchase from you than buy the RS-918
Do you intend to offer a full kit that does include final MOSFETs (and possibly a case)? Or is the currently listed ‘components kit’ considered the full kit and finals are to be sourced independently?
Regards,
Sam, ZL1OBI
Hi Sam,
I will probably offer the case with the full kit at some point, need to sort out correct box and since it will heavy,
see how much will cost. Mosfets, i don’t have a good supplier yet, so no idea.
73
Hi Chris,
Will the blank boards be available also ?
73
Can I make a reservation? I’d hate to see it sold out again because I did not check the website for a few hours …
73, Ulrich
Hi Ulrich,
I don’t have such system, sorry.
73
Hi Chris, please when the last revision full kits will be available ? It’s possible to made reservation for it ?
If is necessary to anticipate some amount there is no problem. Could you advice when kits will be available again ? Thank you, regards
Maurizio
When will the “mcHF v 0.7 Components Kit” be sold?
I already bought from you 0.6 version.
Please, if you can write to me, if there is a 0.7 version on the email (gogymon at mail.ru).
Thanks!
Hi Segrus,
I hope in few days.
73!
Thanks!
Is the 0.7v of the kit the same as the “mini” I keep seeing on Facebook?
Hi,
i believe you are talking about the Polish clone, it is not something produced or authorized by me and it is breach
of my non commercial use license.
73
Hi Chris, I obtained an unstarted v0.5 kit from Israel. I then managed to install the LCD upside-down. Desoldering and removal has caused quite a bit of damage to LCD lands and tracks on the UI board. What options are open to me? Are there any v0.5 UI kit boards available on their own? Or even a v0.6 if it will still work?
Thanks and 73 – Rob G0MOH
Attempting to repair the board with ultra-fine wire, bits of kapton tape, and a strong magnifier! Without PCB artwork it’s a bit of guesswork in places to see what lands go to where, but it’s got to be worth a shot. It’ll either work, or it won’t! If it doesn’t, I’ll have a redundant RF board kit (unstarted) available for sale, as well as a mic, and a case.
Hi Rob,
E-mail me please. I will try to help (djchrismarc at gmail).

Amazing. Will order as soon as you have stock. Thank you for all your efforts and sharing such a decent kit.
Hi,
I have mchf damaged by inversed polarity, does anyone knows what parts I need to change to fix it. Is it the F1 fuse or???
Hi,
the mchf is protected with F1 which will be destroyed by D1 when the polarity is reversed. If you are ABSOLUTELY sure that the polarity is correct, then you can bridge F1 and check if the mchf works properly. You should replace F1 as soon as possible.
Unfortunately I have no mchf. I’m waiting for the kit. It is still out of stock…
73,
Sebastian DL2SDR
Out of stock is all I ever see on this site.
Hi! Do you have an estimation when there will be stock of the complete (presoldered) kit again?
Hi Jukka,
I am sorry, still can’t give exact date for that. But working on sorting it out.
73
Hi Chris, although not (yet) in stock, is it possible to still place the order through PayPal and it gets sent as and when it’s in stock? 73 – Rob G0MOH
Hi Rob,
No point to pay me in advance. When i have stock, i will list for sale.
73
Do you know it will be weeks, month or months? Before the end of the year?
Hello, when is the UI BOARD again to get?
I would now immediately order the RF board and the HY28B LCD.
Many Thanks

is there any way to get on a pre-order list? I understand that it will take time for components to be back in stock, I’m just getting tired of hitting “refresh” every 6 hours 🙂
Hi Andrew,
Sorry about that! But i don’t have such lists as it is huge logistics nightmare as it is, if having such list would be even more difficult to manage it.
73
Quick question, will it be OK if I order a pair of PCBs only, the paypal checkout seems to be allowing that even though only 1 type board is in stock, I can wait till you have both to ship together.
Harry
Hi Harry,
I just found one extra UI board that i had. So if you are fast enough, you can order it.
Sorry for the trouble.

Hi M0NKA,
any update when the COMPONENTS KIT will be available again? I was considering ordering it yesterday, and today I see that it’s gone.
Hi,
Sorry about that, we have the kits, but seems Farnell sent us a wrong component and had to put it on hold for the day.
Maybe tomorrow.

Can I order just the U1 board from the surface mounted kit with the LCD? I got both boards together and U1 programmed but the LCD was bad and of course I had soldered it in. Got it out with only two traces ripped up and it is probably salvageable but.

Hello, Chris. I’m going to order 2 bare boards version 0.6. Is it possible to deliver to ukraine? Payment not through PayPel?
Hi Alex,
No problem to send to Ukraine, i did before. But the only other payment i can take is bank transfer. This would make the two boards
very expensive, because i expect you to pay all charges (yours and mine bank). So extra 30 USD at least. Don’t you have a friend with
paypal to buy for you ?

Chris,
Darn missed it, waiting for pay day and now out of stock on the ‘MCHF COMPONENTS KIT v 0.6’

I see that you are no longer offering the LCD as a part. Is it still included in the full kit? Also is there a simple way to determine what if any mods apply to the current kit?
73
Hello Gregg,
Yes, LCD is part of the full kit. There is a huge list with mods on the GitHub Wiki,
but most of them are v 0.4 related. A must mods might be touch screen mode and the one
i have posted recently about cleaner TX signal.

Hi!
I want to buy x5 complete kits. May I know about the speaker and the final MOSFETs? These MOSFETs are necessary for complete working of SDR kit. If so, then how and where I can get these. Is there any provision to play with software?
Hi,
MOSFETs you can buy from reputable ham webshop, as Ebay ones are most probably Chinese fakes.
Speaker from Farnell or any other that will fit your case. If you do QRP on lower bands, you
can go with cheap IRF510’s instead of the Mitsubushi MOSFETs, the footprint on the PCB will
take them.
If you need more than one kit shipped via DHL, please drop me a mail at djchrismarc at gmail

Usually those chips are programmed on board, first because they have USB Bootrom that allows programming them from the PC, second
it is bit expensive to make dedicate programmer with socket.

This is a really nice looking radio. I have obtained a case and several sets of pcbs and jut recently all the parts from a fellow ham.
My question is would I be better off getting a set of rev 0.5 pcb’s and building them or just use the rev 0.4 boards I have. If i get a set of rev 0.5 boards are there a lot of differences in the bom? If it is just a few caps and resistors that wouldn’t be a problem.
Do you have any information that lists what was changed from rev 0.4 to rev 0.5?
Great project.
Hello Peter,
The 0.5 revision incorporates mods and changes suggested by Clint and community. If you already have v 0.4
you can build as it is and incorporate mods selectively. There are gradual improvements, but not that critical
to upgrade. V 0.5 is not the last revision, there will be 0.6 as well…
Chris
Sorry I forget to pass thanks
73
Hi,
I’m interested in your project and would like to order all parts, but without Paypal, since they dislike to forget me as customer.
To avoid to make this experience again, is there a way to order it passing IBAN and BIC to you directly, or by other means?
Hello,
Sure, but lets sort via e-mail, not in public. (djchrismarc at gmail)

Hello Henry,
Yes, two boards (UI and RF) with all SMD parts installed in the factory – by pick and place machine, then wave soldering. Also in the kit a LCD plus two plastic bags with extra parts – mostly through hole that you need to solder.

Hi Chris !
The Paypal order site looks that way that Paypal creates secretly an account with your data ?!
The password request makes me a bit suspicous.
I definitely do NOT want to have an Paypal account through the backdoor with an order so the question is if that is really the case here ?
Cann you please give a short comment on this ?
Cheers
Peter
Hello Peter,
To be honest i am not sure, i haven’t used PayPal for a long time like this because i have account.
But they are very safe these days, more or less mainstream, specially for the buyers. Maybe you can
delete this account immediately after purchase ?

Hello,
I had components only kits for some time, but it was very labor intensive, me and my wife couldn’t last more than few months under this pressure. This is why now i have either PCBs or partially soldered boards. The only way for your is download BOM and source components yourself, sorry.

I had found the SDR Project by a notice in the db3om forum, where i frequently reads and write.
I was positiv surprised, that the SDR developer move her focus to the ARM Cortex-M4F from ST, instead the microchip PIC mcu’s where tranditionaly used by Radio Amateurs or use a Raspberry-PI instead.
Well, your design is amazing and i am interessting in to build such device too but the Display size is to small for me. How is the load of the mcu if this is operate? Is some capacity left to may support 800×480-16 Pixel Displays?
vy 73 de Gerhard
Hello Gerhard,
Thanks for your interest. As for selection of ARM instead of Microchip, it is simple really. If i wanted to develop Xmas three controller, PIC would be a great choice, but for the mcHF… On a serious note, i love ARM instruction set and the beautiful core architecture. So easy and fun to use. I have used PICs before, they are great for a low power consumption. As for the Rpi – yeah, i could have used one, if i removed the clunky OS and use super loop firmware coded from scratch. But how do you fit the huge board in a small radio ? Just use the Rpi CPU on the UI board – it was not practical.
As for the big LCD – i have tested 800×480 LCD, using 24 bit interface, 8 MB external SDRAM and F429 – it can paint the bandscope and nice
emulated S-meter (like Kenwood 990), and that is pretty all of the CPU power gone. Maybe there will be some left if i code in ASM and optimize, but for this task Rpi would be better – as UI driver, and something else dedicated for DSP and audio only.
73!
Hi Chris,
thank you for you very good project.
The UI-Board I have make complete, the missing 2mm – Header for the display was not a big problem.
I have single-contacts, they ar gives plugged in paper-strips. You can plug these of the contacts from
the display and then can all soldert in the PCB.
I missing the RF-Board with all other things. Can it be, that you send this later ?
Vy 73 and many thanks again
Uwe (DL5KU)
(my email : uwe.kraaz@acousticon.de)
Hello Uwe,
You are not supposed to solder a header socket for the LCD, it is not part of the BOM and has never been. In theory you can solder one, keep in mind those are very expensive due to the non standard pitch, also your UI board will no longer fit in the 3D case. But if you make your own case, then you can use it. Soon i will list some RF packs only for sale. Check my page from time to time (also i post on Twitter).

Thanks for the nice words! 73
Hello Chris, have you received my order on the complete kit MCHF?
Command sent on 01 septenbre 2015 in the afternoon.
Apparently you have to component supply problems.
Good weekend Chris, 73’s to you and your entourage.
Christian LECOQ – F5OTS – FRANCE
Hello Chris,
due to the many different comment I am not sure about the current status of the full kit delivery situation.
Do you have kits available and if so when would you be able to ship (considering you very appreciated load and support)? And, have you any numbers in terms of shipping time to germany? I’d need two.
73, Hans DF4KD
Hello Hans,
I was taking orders upto tonight, but seems i won’t be getting some toroids shipment tomorrow, so i just have the UI board kit for now,
until i sort the situation.
73, Chris
Great project I am considering purchasing a kit myself. As my interest is mainly 50/70 MHz trying to figure out how easy it would be to get it going on low band VHF?
Judging my the many repeat questions you get both here and on the Yahoo page, I think you could do with an FAQ page 😉
73’s and keep up the good work.
Hello,
I happen to run one now on 70 Mhz (WSPR). The VHF side is OZ2M and homebrew PA (some modded Mitsubishi chip). There is also compatible VHF RF board from a Polish OM, but not much documentation about it(so i still haven’t soldered it). Yeah, this blog is crying for update, i wish i had a minute free to do it 🙁
73
Good evening. I have two circuit boards (PCBs UI and RF) components need for the two circuits. I have seen that there is the option for sale (PACK COMPONENTS RF) components also need UI board. Is there an option to buy? Thanks.
Hello,
I am overloaded with orders at the moment and simply don’t have the time to prepare custom orders, sorry. Maybe in a near future.
73
Similar request- if you could post a “UI Parts Only” kit for parts for us that already have a UI board.
Regards,
Wayne
Hi Wayne,
Yeah, i was thinking about that. Not a bad idea.
73
Good morning Chris
Could you tel me is it possible to receiver digital radio in standard DRM/ http://www.drm.org/ Do you predict to do it in the future.

Hello,
To be honest no idea. If it is very computer intensive, might need external decoder. Anyway, not coded in the
current firmware.
73
look here: http://www.amateurfunk-sulingen.de/mchf-projekt/
…some hams who wants to implement such things in the future.

Well, the cost of RF components author is already increased strongly. Well, but that’s a matter of conscience.
Hello,
I have switched from UI board only (179 components) to Full kit (179 + 339 components). You can always download both BOM files from the Hardware page and copy the order codes to your Farnell order. There is also much cheaper option building around 10 GBP discovery board and using stuff from your junk box. Hope this helps.
73
Hello.
I want to buy the folloming:
One UI board, two RF board and one LCD.
on your website are the UI, RF, but not LCD. I hopeyour news. saludos
Chris,
unfortunatly Y1 (16mhz FN971-3808) and C93, 94 (20pF each, FN233-2762) are not be inventurized. would be proud to get them. so how?
cheers – Raimund, DL1EGR

Hi Chris, thanks for the fast shipping. Everything arrived safely.
vy..73 DL8JM
Great! Thanks for letting me know. 73!
Good day
I wonder four things:
a) If the transportation value to Brazil Zip Code 91900-240 , the Tranceptor QRP SDR kit , it is 10 pounds or if not , what value ?
b ) If the recipient of this kit is broadband , covering long and medium wave or is exclusively for amateur radio bands ?
c) if the bandwidth filter in the receiver is variable or only in pre-programmed widths ?
d ) If you can put two kits in one package and declare the invoice only 1 ?
Best regards

Hi,
Please drop me a mail at djchrismarc at gmail. 73
Placed my order serveral minutes ago. Hope to everything is well… Are flashed mcu available?
Hi,
Programming those MCUs in a socket is not needed. It was something we did with old generation chips (Microchip) years ago, but now all microcontrollers have USB bootrom, so it is a breeze to blank program on board.
73
Hi Chris
thank’s alot for quick reply; placed another order for a friend-HAM nearby – so “then there where two” to start the challenge
cheers for now
Thanks for your support! 73
Please let me know when you get ui and rf kit in stock thanks kc2koj
i will post on my blog when it is readly, also probably on twitter. 73
how about parts to RF pcb kit?
Sorry, i am not done with that yet. 73
Hello Chris,
This is looking like a good project, I am considering ordering the UI kit and rf board but wonder if I should wait for a full kit? I’d like to start another build soon.
Does anyone else have lots of finished qrp transceivers they hardly use?
73, Ian mm0gyx
I don’t think i can have the full kit soon enough. Ordering and sorting those small parts takes long time ;( 73
Can I order just a UI 0.4 board as I already have a RF 0.4?

Andy
Please drop me a mail to arrange. 73
hi
how much for the kit shipping included in italy and where order the component list
lou
there will be components pack for the UI board first, later for the RF board too. need few more days to organise everything. Price will be announced as well. Keep on checking this page. 73
Good morning Chris
Paulo Cesar PU2YEI of Brazil
how many board has the radio, I’d like to buy all over the display, also sells the components or are the most boards the display?
Thank you
Hello Paulo,
Two boards – UI and RF. I can sell you those + LCD, but parts you should buy yourself. Check my BOM list or the one from
the Yahoo if you buying from USA.
73, Chris
Dear OM
Being a homebrewer I prefer the make a SDR radio and ie Your design.
So please let me know for one complete set of mcHF kits prices include the mailing charges to INDIA
Thanking You ,, best 73s vu2kd

Hello,
Still haven’t been able to organize full kit. But you can get PCBs + LCD on the order page.
73, Chris
I’d like to order a kit, can you email me ordering info and details on what’s included and what I’ll need?
Disregard, I was on the mobile site. I found everything I needed on the full site. This looks like a great project, I can’t wait to get started.
Hi,
I’m very interested in this kit.
I’d like to purchase two set of it (set of items (UI+RF+LCD max)).
Would you tell me the cost of shipping to Japan?
73!
Hi,
Shipping for one set (LCD+UI+RF) is 10 GBP, international, tracked and signed. I can usually send more items in single package,
but two LCDs and 4 boards in one pack is not good idea, it is getting heavy and there is a chance for the LCDs to get broken during
transport, so it best to order as two separate orders please.
73, Chris
Mistake. Never share any kind of know-how with the guys from China. They will copy your project and sell it as a final product.
73
Hi,
I made this project with the hope that would be useful to the wide ham community and tried to keep it as open as possible.
In my professional life i do reverse engineering and embedded development, it is no problem to implement nuclear warhead
type of security – i perfectly know how to do it, but this is amateur radio project – completely different venue, it is all
based on good faith in the nature of fellow radio hams.
73, Chris
I came across this Chinese website:http://www.hellocq.net/forum/read.php?tid=333734&page=1
Seems they are offering your radio.
Are you working together with these guys?
Andy DC3AFA
Hi Andy,
Thanks for the link. Yes, they have bought large volume of PCBs and they solder, make casing and offer locally to ham friends.
73, Chris
Thanks for the fast delivery of the print, I hope that soon I have some time to start.
There is also a company where I can order all the parts.
best regards, Wim
Just wondered if my boards had shipped yet. I was able to source the lcd online using the part number listed on your parts list.
Hi Larry,
All orders received during the weekend will be sent today.
73
Hi, we are two friends and we are interested in building this beautiful project, but you do not have screens at this time, please warns you when we get and we order two units. Thank you and congratulations on your work.
Miguel
I will post here when i have the new batch of LCDs, please check from time to time. 73
I would be interested in a set of boards with the lcd when they become available. Please let me know.
73 kf4fnm
Hi m0nka,
Any replacement that I can find for the LCD? Are you aware of some similar display I can find around there?
Hi, you can probably use different LCD, but will not match the UI board and the front panel. In theory you can add any LCD with QVGA resolution and similar size, and just update the LCD driver to support it. If you want it just as it is, please wait maybe another week, i will have the LCDs back in stock. 73

Hi,
I’ve ordered on Jan. 30th. both boards & LCD. Can I expect to receive new versions of boards?
I plan to use rotary encoder with a push switch, that will omit few buttons. I wonder if I can change step “in circle” from lowest to highest with just pressing one switch?
73,
Jure
Hi, right now i ship only v 0.4 of the UI board. As for changes – schematics, source codes, etc is published. You can do any changes you want. 73
I have ordered two PCB and LCD for the project, by international shipment and paid the amount by Paypal.
You can confirm payment?
Thanks. 73

Dear sir, I’m new in the ham biz. Your project seems to beawesome and Exactly what I’m looking for as an underbudget beginner. I’d like to know if these 3 parts (2 pcb’s and a lcd) are all I need to build the transceiver? Is there a full kit available with the exact instructions?
Thanks and best regards, 73,
Tal
Hi Tal,
You needs lots of parts as well, the full list is in the BOM.
73
Dear Chris / Simon,
So in general people go to companies like digikey and purchase the whole BOM.
Do you have any idea what would be the cost and the best way to obtain all components.
Thanks,
Tal
Please check the Yahoo group, there are some automated .xls files that can help you. Total cost is about 200 GBP.
73
Dear Chris/Simon,
The UI Board I have recently purchased is Version 0.03 and new board is Version 0.04
Hope the matter is clear now

Greetings and thanks.
When sent, i change status in PayPal to sent. Also enter tracking number. 73
Confused!
Is the new UI board ready then?
I have been visiting the forum daily waiting to hear news, or was the former post wrong.
Are we able to order yet ( in advance?)
Hi,
I have few new boards, waiting for a new batch in a week or so.
Dear Chris
What are the modifications in the new UI board..?
I have recently purchased a new UI Board from you.
Is there any major modifications to this boards.

Hello,
There is nice pdf in the yahoo group by Clint about the UI board.
73
Hi, are you taking orders yet for the new UI.. We are a group of 3 in same office ready to start.
Hi Simon, give me few days to solder and test the new board. Want to make sure all is ok with the board.
Hi, do you have PCBs and LCD available?
I want to order one set right now 🙂
Yes, all in stock.
I have ordered PCB set +LCD for the project.
Please confirm.
Thanks. 73!
Hi,
All the latest orders will be sent today. Thanks for your support!

you have received my order and pay with paypal ?
For any problems, please drop me a mail.
Hello Chris 🙂
Great fun project 😀 I really appreciate your efforts. I just
ordered the two pcb’s from you. It seems that for the US at least it
makes more sense to order the lcd direct from hotmcu.com — do you
think that will be OK or do you do some modifications to it for the
kit? If so, then please wait to ship the boards and I will paypal you
more for the lcd.
Chris, what do you do in life? Are you a student or do you have a
career? It seem you have great background and energy+time to do this
project. I am impressed!
73 and have a great day,
Mark/n7eku
Hi Mark,
You can order directly from China, np. Make sure you move the jumper before soldering the LCD to the UI board(need 16 bit mode). I do embedded development and Reverse Engineering for a living.
73, Chris
Hi Chris! Are the Gerber board files available for this project? I would be interested in just ordering boards from my usual board house here in the states. Thanks!
Hi,
I have released the project for personal, non commercial use. Supplying the gerbers and other manufacturing files would
be beneficial only to people who plan to start mass production and sales.
73, Chris
Hi Chris
Just orderred for RF PCB + UI PCB + HY28B LCD. My PayPal transaction # 6KP04308DP576410H dated Dec 15, 2014. I can source for UI, but can you suggest where I can get RF PCB components from a single source or do you supply? Thank you
73
bkrish
Hi,
Please check PayPal for tracking number. As for updated BOMs and order lists – check the Yahoo groups, some US hams made detailed ones, in the Files section.

Just a little constructive criticism. I can’t tell if you’re selling this SDR or you’re providing instructions on how to build it etc…..if you are selling is there a complete kit….
While this may be indicated somewhere in the blog at my glance I am unable to find it. I am looking for an SDR transceiver (QRP is fine). I can’t tell if I can buy it here.
Kindly let me know.
Thanks
Dan
Hi Dan,
I think i have mentioned before, i am very busy with our new home extension, this takes 100% of my time, until this is finished, i can send few boards away, and maybe bug fix here and there. Sorry.
73
Chris,
Looking Forward to receiving the boards and display.
Chris ( G4JSP)
All sent, so you should have it soon, 73
Hi Chris
Oreded The 3 Parts 🙂
I will look at new boards once you have finished working on them
Best get looking at the bom and see what parts i need to order
And get a good Soldering iron and heat gun
Anybody got any recommendations ?
Thanks again
Simon
M1BVX
Hi Simon,
For soldering iron i use ERSA i-con nano, as for hot air, look on ebay for cheap Chinese ones – any that allow temperature and flow regulation with LCD will do.
73
For hams who are not the quickest at building projects, it may be advantageous to only select one
board and then build it up, and then order the next. It would be especially nice if your interconnect
(cables and connectors) are not going to change between revisions, then we could order a board to build now that will have the less number of revisions on it, and when we have that one built up.
in a couple months order the next board that would be your newer revision.
For some people it may be worth it to pay a little extra on shipping to have this option.
It is a very appealing little radio, in any case.
Hi Joe,
I am keeping the interface and protocols compatible, in new revision i implement only tested mods, that do not change the overall functionality of the radio.
73
Hi Chris.
Coul you confirm that my payment received by you?

Hi Chris,
I thought only the PCB, without displays.
so one more time, please how much postage would happen to Slovakia for 5 pcs Set PCB. Thank you.
Jozef OM1CI
If its only 5 boards, no LCD, maybe i can manage to sent as stated international shipping.
73
Hi Chris,
I need a couple of UI and a couple of RF pcbs but also one LCD.
There’re some shipping cost difference?
Thank you

Hi,
The price is based on weight, if its too much it might be cheaper with DHL. Please drop me a line to my mail to discuss.
73
Hi Chris
So i just need the 2 boards and the LCD and the bom of parts
Are the boards due for any more tweaks or are these the final ones for now
Also whats is the approx. cost of parts and do you need a oven to solder any of the parts
Sorry for all the questions
Simon
Hi,
I am working on new revisions of the both boards, but it will be 1-2 months maybe before all is done and tested. There are some mods explained in the Yahoo group. Total cost of parts is about 200 GBP. No need for an oven, but good idea to have hot air station as addition to your iron.
73
Many thanks will wait for new revision will soft ware be same on both boards ie one you have and new revision trying to follow the group 🙂
Thanks again you have all 3 parts in stock at the moment
Simon
How much would it cost approximately to order a kit with all of the parts in US dollars, and do you have any plans to add vhf/uhf at some point, as well as an sdr output for viewing and controlling through a comuter?
Hi,
No kit yet. As for add ons, maybe in near future. Still not fully back to the project. 73
I received my PCB mcCHF,
I’ll get to work.
Very good quality PCB.
Congratulations Chis.

I’m following for while the discussions on the hardware and software.
Looks great.
We would like to order 2 complete assemblies (ui & rf pcb + lcd)
Do I have to select twice an international shipping cost or can you ship combined to Belgium?
Nico
Hi,
In theory you can order two sets, but will be in same small C size envelope, so there is a danger of damaging the LCDs. Up to you.
73
great job, I wanted to know if you have availability of boards and displays, and if you can send in Italy
thanks and 73
yes, all available.
Hi m0nka,
I would like to buy a kit with all the components. Is this possible and how much would it cost?

Hi Mani,
E-mail me pls. I believe DHL will be around 45 GBP.
Ordered one full set of pcb’s and lcd, looking forward to receive it and start working on it.
Can anybody tell me an estimate of the cost of all the components? Just an aproximate value.
Thank you,
David EA1IDZ.
Hi David,
Package was sent yesterday. Total cost of all components (including LCD and boards) is around 200 GBP.
Thank you!!!
Received! That was fast!
Thank you.
Please, make il possible for a kit.
There are so many radioamators out there with no much money, and a kit form is their only option for HF.
I will follow your project, hoping for a soon to date kit.
Regards. John.
Hi John,
That is a plan, but have to wait few months till i finish my house extension project and move. These days i spend my time on the building site, very little time to play with the project 🙁

Hi Robert,
It is the first time i hear about this CPU. Is it cheaper than the one i use ? What is the reason you want to use it ?
73
I have access to it, and that’s all. Why buy a new
Hi Chris,
There are many devices in the range of 0.1-30MHz. There are not many TRX at 50MHz and 70MHz.
Whether a change the antenna filters and the software will receive 50 and 70MHz?
Converter ADC which has a frequency end?
Whether it will upgread firmware for modulation FM?
Vy73 Artur
Hi Artur,
I have read that by carefully selecting the mixer switching chips it is possible to achieve 50 and 70 Mhz. This will also require the more expensive SI570 versions that can go higher than 160 Mhz. From software point of view this is 10 mins coding, but for VHF you need much better front end, pre-amps, filtering, etc. Also i see in KX3 they push the same final for 50 Mhz as well, but not sure how efficient is the whole thing in 1-50 Mhz range, requires real knowledge in analogue design to make this.
73, Chris
It is the CDR TRX. Is it possible to write firmware for modulation
FM. I’m interested by the device can be set to 50MHz and 70MHz.
Is the ADC will work to 50MHz/70MHz?
or if you need to do TRV 28MHz/50MHz and 28MHz/70MHz

Hello,
I have an order for big quantity of UI boards, it will be here in one week time. Also the RF boards that i got yesterday are almost gone, will make another order and will have them in 10 days. Sorry about that. I did not expect such demand.
73, Chris
good to look on the page daily, and Chris thanks to Yoru fast rpely!
As per today both boards and the LCD are available I just ordered the three items using PayPal for payment. If PayPal does not dieplay my adress please respond to my email adress!

arailabiltxy of boards: what a pity, now th UI board and LCD are available but the RF board is sold out! As the shipping costs to the outside of the UK is so high I waited for teh order of the RF board which was avaliable — last week? Now I can order the other baord and esseantila LCD but without the RF board the Transceiver is not complete. Is there a Chance when all three baords are avaliable at the same time???
Henning Weedig
DK5LV
Hello,
The postman suppose to bring the RF boards today, but nothing. Hopefully tomorrow.
Chris
Hello Chris,
For postage, I deselected the 4 GBP and selected international (6GBP), but I realized afterwards that it should be 10 GBP, therefore both must be selected, right? 6 is additional.
I also see that you do not have RF board available anymore… for the same postage, I would prefer to wait for it.
When will you have them again? Thank you!
Cheers, Jose.
Hi Jose,
Yes correct, the base postage of 4 GBP will be included anyway, but covers UK recorded delivery only. So that is why for international need to add extra 6 GBP so total is 10 GBP(the international recorded cost). It is simple shopping cart plugin and this is the best i can do right now, sorry.
RF boards i will have in hopefully one week time, as far as i get them will update the Order page.
Chris
I was looking for the gerbers so I could create a solder mask to make the build quicker.
Ciao Chris,
Very interesting project.
Will you sell UI PCB as well?

Hi,
Yes, i have some UI boards now, probably will update the site tomorrow as i am waiting for DHL to bring some LCDs as well. Those are the HY28B – dual interface version. The latest mcHF firmware supports all the three versions manufactured by hotmcu.com.

Hi Chris
As HY28A can be compatible with HY28B as the pins are arranged differently SPI and paralel?
Hi,
If HY28A is detected on boot up, the SPI is used, if HY28B – the parallel is in use. There is no change of the location of the 16 bit parallel port pins on the three different LCD modules.
I love this radio great job!!! I have been wanting to do this myself!!!
Do you have the board layouts, and or a full set of boards avail for sale?
hello,
All the documentation is posted on this blog, just dig deeper into the menues 😉 Any more questions, mail me pls.
As for boards – i have few RF boards left, waiting for a batch of UI boards and LCDs delivery, i hope in few days.

I really like the idea of a kit (may be only the “hard to get” components) and suggest to introduce a list for people who want to buy a complete set of pcb´s / LCD and/or kits.
May be this is then easiser for the designers to estimate the next pcb run ?!
Hi,
I will do this eventually, but wanted first to test few things that i was not sure are final, before order bigger quantity. Now i order in small batches only, hopefully soon.
Chris
hello,
do you plane in the futur to provid a kit including box and excluding resistors capacitors.

Hello Pedro,
I need to do a little bit of tweaking still on the boards/schematics, to be sure all is ok. Doing very active
testing with my friend Brian(G0JMI) and soon hopefully i can have a kit. So far i can offer the two boards, and
have maybe 3-4 LCDs left. Please check the order page.
73, Chris
Available in kit form, please send money.
thanks Alfredo iz1pmx
Dobrý večer.
Chcel by som sa informovať ohľadne stavebnice mcHF QRP. Chcel by som si ju objednať ako celok so všetkými súčiastkami a plošnými spojmi. Je to možné ?, ak áno čo by to stálo.
S pozdravom KOČIŠ.
Hi Kocis,
Sorry, can’t offer assembled boards yet. Maybe in near future.

DigiKey, Mouser or Farnell are your best friends here !
Hi Chris,
As i need only a complete Kit (except loudspeaker and mosfets), please le me know.
I will order and send money then via paypal.
I alo need to know, how much the shipping costs are to Germany.
Best regards
Joern, DF 2 HB
Soon will be available on the Order page, but limited quantity, based on what i have prepared already for sending, to prevent long wait, like the last two weeks.

Planning to purchase boards and parts to build my own and really like soldering and got the tools and looking for ways to cut costs. Maybe I can build for one or two extra besides mine if someone likes the project, but lackes the abilety to buil
