Thanks Wilhelm, that is already set.
The issue isn't SDR Console, but hardware side. As I said I've got it working when I have separate power supplies for the biased tee and the rest of the equipment, but when they share the same power supply I lose Rx on Tx.
Hello,
I've built a Pluto+ SDR QO-100 setup, typical design: Pluto+, CN0417, SG Labs PA, and ice cone to 80 cm dish. Then a bullseye LNB on receive, as below:

I'm using SDR Console, but I've found when I transmit I stop receiving - the waterfall goes blank and I can't hear anything.
I then tried using an external 12 V battery for the biased-tee and then everything was fine, I could recieve whilst transmitting, so I assumed the PSU maybe wasn't suitable.
I then tried powering everything from the battery but the same issue returned. This leads me to believe there's 2.4 GHz rf coming back into the setup, entering the biased tee and causing interference in the Pluto+ (?).
I checked the VSWR of the coax and ice cone downstream of the PA and it was 1.1 across 2400.000 MHz to 2400.500 MHz.
I'm not sure what to check or test now - any suggestions?
Thanks.
