Well. Got my uBitX built up and made a couple of contacts on 40 meter SSB. Good reports and they are looking into getting them also. I am powering the radio with a 21 volt LiOn battery pack I built.I have a CV/CC regulator built into the power supply set to 12.1 volts 2.5 amp max. All is stock in the radio. No mods yet... Well one little one .. I added a 78L05 regulator to send 5 volts to the mic as I have placed a MAX9814 AGC board in the mic.? My heat sink is from an old marine VHF radio. Doesn't even get warm.
Here are a few pictures of the project. Graham VE3WGW -73-
