[RFI] Non-RF sensitive hardwired smoke/fire alarms?

[WD8ARZ]

Will never forget an experience I had while living in a studio hotel 
apartment while house hunting after a new job relocation.

Didnt take long when I was missing ham radio, so I strung a thin random 
wire out the hotel window through some trees. You know, just for 
listening ...  wasnt too many days and I was wondering if I could load 
up on that wire and have some qso's on hf. While tuning up, the hotel 
fire alarm system went off in the room next to mine ...... wasnt any 
doubt in my mind as to why. Quickly pulled the wire in and put it and 
the ham rig under the bed .... fire department came and went puzzled 
about the false alarm.

Sorry about that!
