[Elecraft] rf interference on smoke detector

[Ron D'Eau Claire]

FWIW, I have new First Alert Model Model SA300 smoke detectors. They are
powered by 10-year batteries. The end of my 110 foot inverted L antenna
comes right into the shack through the wall to the tuner on a shelf about 15
feet from the smoke detector. 

I have used that antenna at 500 watts on 160 through 10 meters without
affecting the smoke detector.
