[Elecraft] OT: Kidde smoke detectors; Any follow up on RFI frm wireless models?

[Lyn Norstad]

I have a fairly new Kidde wired system (battery / AC) with a total of 10
sensors on 3 levels.

No RF issues with KPA/KAT500 at full power on any band 160-6m, any mode.

Hello,

I read the thread from several weeks ago discussing the Kidde wireless
interconnected smoke detectors and the concern that they would be triggered
by RF from ham radio.

Has anyone who is running any power tried them?

A local ham running 100 watts hasn't had problems.

I have a Kidde wired interconnection smoke detector system that I trigger
with > 250 watts. Numerous attempts with ferrite chokes and bypass
capacitors haven't resolved it.
