[RFI] RFI With Smoke Detectors

[Howard Lester]

Stan, my hardwired alarms are First Alert 9120B, Lowe's item #304196 I
bought as a 6-pack. I have no RFI problems with them. Maybe you should
consider switching out what you have.  ?  I run 100 watts 160-10 on a 140'
long inverted-V about 30' high at the apex, and about 35' from the house. I
also run 100 watts on 6 meters to a small antenna mounted on a 15' mast
attached to my back deck, thus about 12' from the house.

> The system is set up so that a fire on one side causes alarms to sound on
