Before I got my K3 I had a ham move in 1000' from my antenna, and I wasn't pleased. In my previous location in AZ, I was 1700' from a ham too.
In both cases, I used an ICE front-end saver, which is cheap insurance. See http://www.iceradioproducts.com/reconly.html#rflimiter . I used a Model 196, but I see they also have a model that includes a lightning arrestor / static drain, and another pair for 30-500 MHz. I'd like to hear from someone more technically qualified than I am (that means almost anyone) about the adequacy of the ICE units. My last neighbor was in a rental house. He moved out after a year, and I breathed a sigh of relief. Jim N7US -----Original Message----- Yes you should be concerned. I would think about bandpass filtering and probably disconnecting the K3 when not on the air. I was looking at the mods for the K3 and noticed one that addressed this issue. Are we talking city lot or 20 acre parcels?
