[RFI] RFI With Smoke Detectors

[Roger (K8RI)]

I have 3 smoke detectors and 3 CO detectors.
The CO are independent and run off 120 VAC, the smoke detectors are 
independent and battery operated. No AC connections.  No RFI, 160 
through 440.  I run the legal power limit  160 through 10. The house is 
under the 160 half sloper and within 60 feet on 144 and 440. the other 
antennas are 90 feet plus.
Tribander is down, but getting ready to go back up.
