To chime in, I show the same currents on my uBITX (320/3).? I see 380ma? PTT, Bias full clockwise.? 160ma on, no PTT and volume very low. I set the biases to end up at 600 (110 each).? When I

I've got the same issue - low power, and low current consumption with PA bias at zero.

If you are like me and not having a lot of luck with SSB QSO due to the recent crappy conditions or want to debug your apparent low voice output the Reverse Beacon Network can come to the rescue.?

The RadI2Cino is an almost exact drop-in replacement for the original *uBITX* Raduino card.?It does require the addition of one push button switch and it will also benefit if a separate “hand

Thomas, Thank you for pointing that out, I had forgotten about that option. dieter

More information: I followed the PA bias adjustment per HF Signals. Lower than specifications! Receive current?= 150 mA PTT pushed with both bias presets fully clockwise = 380 mA.? Should be higher

The arduino nano board is very limited and memory is about maxed out. I’m working on porting the firmware to Teensy which has much greater capability. I also plan on incorporating WEPR mode using

is there a mod for cw that goes with the w8tee bitx40 tft vfo board ? we are trying to do as many mods on a bitx40 we can but I need listings for all the mods

who was it that made the replacement vfo for the bitx40 ? I wanteed to see the other vfo he was working on

Any rf decoupling at mic input and amp output?

Many years ago I built the BITX40 kit.?? It was the one with the red LED display.?? I am now waiting for my uBITX to be shipped.?? I built a SMM2167 microphone amplifier/compressor on my own

Ron I agree with all the previous comments about your wiring, it does need sorting. Looking at your photographs I think your speaker impedance is 4 ohm, the one I have looks the same type but is

Ron, Unsolder your speaker leads, twist them tightly together and resolder them to the speaker. See if that helps. Try a .01pf capacitor between the solder lugs on the speaker. See if that

Attached please find the announcement from wsjtx group by Joe Taylor. Please find the mention about ubitx connectivity with wsjtx. I think now the Raduino as well as other versions will be able to

I believe I found the answer in my youtube comment. It looks like you are building a bitx20a from scratch. A good place to look to answer your questions is

Exactly which version of the bitx do you have? bitx version 3 from Sunil? If so, here's a place to start. http://golddredgervideo.com/kc0wox/bitxver3/bitx20version3.htm Leonard

While I agree somewhat I am not in favor of an automatic antenna tuner because if your wire (especially with a new antenna or experimental antennas) and supporting arrangement leave you without a
