I would also have a quick question. I built an ubitx V5. My problem with it next is when I want to switch to trasmititng with the small micro switch nothing happens. If, on the other hand, I press PTT on a USB cable with Pocket RXTX software over USB, it switches to transmiting immediately.
My question is , is there any other place where the PTT switch is available besides the pin 5 of the contorls connector (ORANGE wire) and the GND (BLUE wire).
I would like to ask if I put a switch between the spindle pin 16 (T / R) and GND, would it work as a PTT switch?
That is, if you look at the PTT switch, the orange wire of the VFO panel and the 8 pin audio connector (blue wire) of GND. However,
