sBitx v3 - original application gives high power, wsjtx up to 2W only


 

Hi,
?
Due to the problems with non-standard callsigns, I have decided to use wsjtx.
I have updated sbitx with the `update` script.
?
I start it via VNC.
  1. I installed tigervnc on my sBitx
  2. I log in to my sBitx via: `ssh pi@... -L5907:localhost:5907`
  3. In another console on PC I run: `vncviewer :7`
  4. Then in the vnc session in a terminal I run:`killall sbitx; cd ~/sbitx; sleep 1; ./sbitx`
  5. In another console I run `export DISPLAY=:7 ; wsjtx`
  6. The wsjtx is configured as described here:
  7. I set Digital mode in the sbitx and FT8 in wsjtx.
The result is that I can see the received FT8 messages, I can transmit, but the power is limited to 2W (as reported by sbitx).
I can control the power with the slider in the wsjtx window. The power is proportional to the slider position, but the upper position gives 2W.
?
When running only the original sbitx application, I can control power up to 20W and higher.
What is the reason of that problem and how can I cure it?
?
