The reason to keep smoke detectors from Amateur Radios is that they detect smoke by ionization from a radioactive source. A strong near field will set them off. The good news is that this is your indication that all is not right at the feed line (Or the antenna is unhealthy close). I have had this experience myself, fixed the feed line and the issue went away. That was with 100w on 80 meters. Unlike real smoke, the detector will stop complaining when the transmission stops. -73- Geoff W1GCF
