New revision V0.8 on it’s way

Hello Everyone

The mcHF project has been running for almost five years now. Thank you all for your continued support. We are constantly trying to make it more fun and implement the many ideas we have as well as take on board comments from users.

Currently we are working on a very exiting revision V 0.8 . Some of you may have seen new image uploaded on our Home page or twitter posts giving a small preview about it. Still to come are many days of active development but once work is complete we hope the wait will have been worth it – upgraded UI board, fully compatible with the Logic, RF board and case. New 5 inch capacitive touch LCD allowing for more user friendly interface.

We also are planning to start operating on pre-order basis, the details of which we are still discussing. This will allow us to be faster on implementing bug fixes as well as updates on hardware and a better chance against competition. We have not been very flexible in doing that due to various reasons. We have tried to cater for as many hams as we can. From the types preferring ‘solder all yourself kits’, to partially factory assembled ones. This has resulted in having to carry an excess stock of components, cases and Lcd’s.

In the start of operating the new way, we would like to offer few left over mcHF V 0.7 kits at a reduced price. Please refer for more details here

We hope we’ll have your support in this matter.

Kindest regards
Chris and Lucy

The ‘Potato’ mod on rev 0.7

Hi,

Changing 74AC74(U11) with PO74G74A has been suggested for a long time. I can confirm it is safe and easy to do, here in few simple steps:

1. Remove U11, preferably by hot air. Turn the board back and cut the 5V trace in the corner

2.  Solder the new chip and put a small wire between the two decoupling caps (hot side, not GND)

You are all set!

Debug port fake panel

Hello,

As i have came back to active development (hardware and firmware) i found the need to update the boards with debug connectors. My obvious choice is the 6 pin Nucleo connector. The ST serial interface allows for fast programing from any IDE and real time debug (with 2 Mhz instead of printf via slow UART port).

Right now there are two debug ports, on the Logic and UI boards, so this panel reflects the position of those. If you have a printer, you can make one yourself as temporary solution, while debugging and keep your original aluminium panel intact.

 

And here the STL file: fake_left_debug

PCB’s v 0.6 sold out

Hello everyone

We were totally taken by surprise how quickly Pcb’s v 6 sold out. We already placed another, larger order this time to meet the demand. The factory we use are very good and quick. We’ll have more stock by end of next week.

In a mean time please accept my apology for not showing ‘out of stock’ on the website. We are experiencing some technical issues at the moment since we added Pcb’s as a new product. Looking to resolve it as quick as we can, but if still not successful I’ll post as soon as fresh stock arrives.

Sorry for the inconvenience.

Kind regards

Lucy
