Hi, I have the same board. Is the connection correct? The yellow wire would not connect. I believe. Thanks!, LU1DLA Alejandro

Jerry, that was the point - I forgot, that my BITX has the BFO mod. mny tnx :-) But yes, the BITX runs well with v 1.28.1 - all Button functions and CW are possible, except frequency tuning ... So, no

Thanks Jerry. My original thought was to follow the trace and solder to the end of the cap but wondered about the possibility of 'stray' rf coming from that trace. I’ll take the easiest route 😉 and ke

Brian, The regulator is a big 3 pin TO220 part hanging off the side of the Raduino. The display and the Arduino Nano clone plug into the Raduino. These 3 previous posts are all talking about how to go

The uBitx aspires to be a minimalist SSB rig. For most of us, half an S unit down on 30m is not an issue. But could adjust the firmware to select the 20m LPF, the operator manually adds an external 30

I once was very much interested in 6m AM/SSB mobile, and I'm presently very much interested in 2m SSB, but there is almost NO activity in central Florida (at least this area) - and my antenna setup is

Hello guys, VU3EDU Subhash from india here. I was wanting to mod my bitx40 to add a touchscreen display like nextion to it just like on the ubitx. I did a lot of research on it, but only was able to f

Do us a favor and include the schematic you are working from. Then we don't have to repeatedly query and guess. Allison

Well, D'ang, it was, after all, designed around 12 volts DC not 9 or 9 1/2, etc. The bareboard kit I have, which uses a separate power supply and PA final on one board, is set for 12 volts for all but
