I have a smoke detector operating on 120v.a.c. that is positioned on a ceiling approximately 4' below a G5RV antenna on a transmitter operating at 100 watts. The smoke detector has given me a false alarm twice in a period of 3 hours at a time when i was on the air. Is is possible that i have RFI affecting the smoke detector? Thanks, KJ6VAU Bob Collier |

I have a CO2 detector that is very sensitive to 40 M operations, but my smoke detectors are OK. Yes, your signal is probably causing the false alarms. You might be able to shield them or move them to a more favorable location, or install an AC line filter. (Or move your antenna or feedline!) 73 Martin AA6E |
