I had the same thing happen in the 1970s. The antenna was close to the smoke detector
in the house . Outdoor dipole I know , but the RF field must have been just right, at the time .
The detector would 'burp' on voice peaks , SSB .
The fix was to reduce power some and reduce transmit audio . ( Swan 350C )

At a flea market today , picked up an old Jerrold
FSM , model 727 . Anyone have experience with this ?
Looks like it has audio built in , and can receive
from 5 mhz to 216 mhz .
Have not plugged into A-C yet.

Back in the day - early 1960s , I was SWLing the
160 meter band nightly, especially winter.
Anyway , I would listen to these 2 hams Qso ALL night,
discussing radio theory . Wow .
I was just wondering who these two guys were ;
college guys or insominacs ?
They had good knowledge of radio theory , at least I thought so .
I am living in Minnesota and these 2 fellas had W2
call signs .
My ' receiver' was a tweaked radio in an old record player / radio and a wire in my bedroom . 5 tube ,
ac-dc .
Anybody out east know ?

I would probably select the 40 - 10 meter antenna.
Also, watch your power level. People are not
stupid. Any TVI , etc , they will find you out !
Don't make any enemies.
Try 10 to 15 watts . And have fun .

Does any one own or even remember , the Skytec

tone, or tighter audio ?
I think it was cw-1 model . Anybody want to sell one ?

Howdy - I was thinking of making this transmitter for the 15 meter band.
Am I jumping the gun yet on this band ?
Also , anyone see any possible problems by doing this band with that particular circuit ?
I live in an apt building, some have cable tv and some use the roof antenna.
I don't want to make enemies at this point. ( TVI )
