Hi Gerard,

I was seeing a similar issue and found this discussion.  Installing the diode made a big difference on my V4 rig going from RX to TX.  Maybe this is  related to your problems?

Evan,
Yes, actually on my diagram,the power supply is the TX for the transistors of the last power stage. It may be a bad design of this model. I looked at the v3 diagram, V4, the alim is still the PA-PWR.
So I would modify the circuit accordingly or disconnect the 2 capacitors because i made only reception at this time.

otherwise, there is some software to pilot ubitx
From a historical perspective, TSW had a release that supported remote control and mouse
control.
