I have a similar if not the same problem. My transmit power is very low in all modes.? This is with a 1:1 SWR. But, if during transmit, I slide the volume slider up I can raise the power to what

still in testing mode yet but when I rebuilt sbitx with your revised files, i got an error: pi@sbitx:~/sbitx $ ./build sbitx >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Mon Mar 18 03:21:11 PM GMT

Regarding the SSB peaks. I haven't put this on an oscilloscope -- and won't know until I do -- but i have always felt the analog-measured average powers when speaking into a microphone were very low.

interesting.

Latest update: Replaced Jabra headset with a UGREEN branded usb sound card that takes 3.5mm jack inputs for speaker/microphone. Using a splitter to allow the usual 3.5mm TRRS connection from a pc

I will revisit this thread tomorrow to read again and implement some of the suggestions. But I am experiencing some erratic encoder behavior now as well. Not sure if the encoders are dirty or the pi

Hi John, I suggest upgrading to the KD8CEC software.? I found that better than the stock software, as the tuning was not based on how fast you turned the encoder.? You could set the tuning step

I picked up a basket case ubitx v5. Pads lifted. Parts shorted. Terrible soldering. I got it going but don’t understand how to change the tuning step size. Playing with the BFO settings but tuning

Hi Ashok, The issue is that the mixer (modulator/demodulator) is not perfectly balanced or terminated.? This allows some BFO (carrier) to "leak" through.? The mixer would not allow the BFO on the

Hi Evan, Thanks for the reply. It looks like BFO issue. This problem is appearing with new Arduino Nano that I installed and calibrated. The same problem did not appear with the original nano that

Thanks Gordon Looking forward to trying it, will let you know the results Regards Paul

The real gurus do some difference testing between files. Also, since I included the entire source files, you could simply re-compile.

Look for GLG

Thanks Gordon now I know which files to alter I can do that, I am assuming that you commented your changes in thise files so I am able to easily spot what changed. Looking forward to testing as I

Well it sounds to be good reason for price drop. Let me ask few more things please. Is it possible to order v3 in famous original dark grey colour of v2? The new black colour is appalling (sorry to

Yes, that was the general reason. There isn’t really any other change that had any cost impact. There’s nothing left out. Gordon

Paul, you would need to have the changes that I made to sbitx.c and sbitx_gtk.c Incorporated in the 64-bit software and then re-compiled to make it work. Eventually I’ll learn how to use the GitHub

Pure speculation on my part, but the cost of a Pi 4 has dropped back to normal. I know that the shortage Pi cost was an issue at the time of? sBITX introduction. -- 73 Bob? KD8CGH
