New mcHF group

Hello everyone,

It is probably known by now that Yahoo is closing it’s group service, so we have decided to move the mcHF group to  Will try to keep settings the same, so membership will require approval by moderators. Also will try to backup whatever we can from Yahoo, as they will delete all files and photos on 14th Dec 2019. Unfortunately the automatic backup didn’t
work, so we are doing whatever we can to download everything manually.

You can access the new group here.


Pre-built mcHF transceiver kit V 0.6.3

Pre-built mcHF transceiver kit V 0.6.3

We are pleased to start offering our new service to all USA Hams. This is only a trial run to test interest and we’ll do our very best to meet the demand. At the very beginning we’ll release small batches of 5 mcHF kits to allow for sufficient testing after each build is completed. Shipment will be with USA recorded postal service and is included in the price.

We’ll be working towards introducing this service to all EU countries and I am hoping in near future worldwide.

Thank you all for your continuing support of the project.


mcHF 0.8 developments


I haven’t been posting here much lately, but last month or two i was able to work a bit on the rev 0.8 source codes. There are total of five projects that are needed for the new revision. I will use my spare time to bring everything up to speed. If interested, please check out my GitHub page:

As for availability, it is still challenging to finance mass production of the new kit, so for now we have only built few prototypes for testing and development.

Modded firmware


The supplied image for latest 0.6.x sub-revision will usually give error and long boot delay due to removed MCP9801 chip from the RF board. If that is annoying to you as me, please flash the supplied modded image. I have also included IDA disassembly and i assume is possible to do simple binary search in future revisions and modify.




mcHF 0.8 Center/Fixed mode

I have recently seen that TS-990 video showing of the fixed mode and couldn’t sleep until i coded this. I was lucky, Clint has left something useful in the audio_driver.c file few years ago(yay, open source)

I am sorry for the bad quality, not easy to shoot the glossy screen, plus i only have my phone. But at least the band was open tonight!
