uBitx almost finished by Bore Lezaic into CM2KMK PCB

P.S. this CM2KMK version is based on very old (1st) Farhan's schematic. See my blog for details:

Hi,

I never see video with QSO from Bore (and other) with uBitx. He and I builded CM2KMK version (Bore with SBL-1, I'm build original Heriberto CM2KMK design). Receiver is worked, but transmitter is not worked. I think, signal level from last mixer is very low and not drive PA stage transistors. I'm freeze this project now (I'm build 2 versions - 1 original CM2KMK and 1 with LZ1LDO modification in PA stage). Also audio (with TDA2282) and AGC provide very poor and low audio signal in both versions (my friend LZ1CLK also build original CM2KMK version, and also have similar problems in audio stage). I don't know why. I think, we need to wait finished Mr. Farhan development and buy from him original uBitx ;)

73!

Folks, the fellow in Cuba who designed the single-sided board sent me the GERBER files, etc. I have posted then in the "files" section of this group in a file called "UBitx files from Cuba".
