I have 2 SDR-1000 and run them in an SO2R in a 1500 watt environment. The only other precaution I take is that I ground the antenna input of the radio not in use when I'm transmitting. I use a relay switching system I devised for this purpose.

Thanks for the suggestion Wally. I'm still concerned about overloading the front end of the rx if it doesn't go into a full standby. Even with the antenna changeover, a legal limit RF field can be quite strong for a nearby rx. Eric, have you any comments on this?
