Installed new security camera at my firing range which, when triggered, sends RF signal to start DVD recorder. Neighbor,1/4 mile to the south,had his remote starter activate on one of his cars several times. As he knows I have quite a few RF items he mentioned his problem. I checked his receiver frequency and it was identical to my camera. Changed board in camera xmitter to different freq, problem solved.
With so much more RF involved in homes, is cross contamination becoming a problem?
