Hello,
I suppose the PA relay control from my SunSDR2 is broken. I have all time (Tx an Rx) about 50 ohm between pin 13 an 15. PA Relay connected all time.
Probably because of RFI ExtCtrl . I used connection with protection Diode. It worked properly days and days but suddenly it broken.
Is there any possibility to repair it?
