Reply To: question about safe antenna distance from transmitter antenna

[diysdrParticipant]

since I’m using the same antennas for rsp and my ham rigs I made a small switch box with a relay in it. If I key the xmtr it not only switches the antenna but also gnds the input to the rsp1 just to be safe(r). the exact answer to your question is going to be “it depends” on so many things. It would be nice if rsp had some kind of input high voltage detecetion device like a relay or neon bulb but it would probably reduce sensitivity.
