[Elecraft] Smoke detectors

[Geoffrey Feldman]

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.
