My current setup to operate ES'hail & QO-100.
The cable from the power amplifier to the antenna is Aircell7 from SSB-Elektronik. The cable from the LNB to the Bias-T is a high quality 75Ohm TV cable.
For DC power connections I'm using the WAGO clamps 222-415 - easy to attach and remove.
This setup runs completely on 12VDC - for the notebook I have a small DC//DC converter :-)
To overcome the instability of SDRConsole & LimeSDRmini I'm using a cheap USB-Headset with a microphone mute button.
I'm running the limeSDRmini in FULL-DUPLEX mode and switch SDRConsole to constant TX. When I mute the microphone in the headset - no RF is emitted.
To switch from RX to TX I simply unmute the microphone the the switch at the headset. The only drawback is, that due to the full-duplex mode, you hear yourself with a delay of abt. 1s - you have to handle yourself.
