You hear the big noise after switching TX to RX when you use OmniRig and Diversity. I think the diversity in SDRuno always tries to maximize the S/N ratio automatically.
I don’t think it is good idea. it can perform wrong control during TX mode and after returning to RX mode, it suddenly tries to correct setting. But it takes time and it generates big noise during that time. I have used the diversity function with Redpitaya+Thetis system. It works fine.
I hope this problem will be fixed. Unless I don’t want to use RSPduo+SDRuno.
