I'm new to SDR so be kind I've read that SDRs overload easily, though I have not yet experienced that and I am not quite sure how it might manifest (IMD, RFI, de-sense, etc.). But I wanted to know if there are any techniques or tricks to prevent that. In the future, our contest shack we will have SDRs running basically everything on transverters. Some things come to mind: better shielding, ferrites, etc. I don't know other than perhaps a bandpass filter if there are any other things to look at.
