OK, Folks, I can use some help here, not for me, personally, but for some
fellows on another forum (600 Meter Research Group) who are having
problems getting into hard-wired smoke-alarms.
Their frequency of operation is at or near 500 KHz. One fellow is setting off
his own smoke-alarms, and another fellow is getting into a particularly
difficult neighbor's alarms.
The second fellow's neighbors called the FCC and complained to them. The
FCC contacted the ham, and when they were told what and how he was
operating, they told the neighbors to go to Radio Shack and buy some
filters....which didn't particularly satisfy the neighbors.
Anyway, might you people have some suggestions as to solutions for this
problem? What sorts of filters would work to keep from setting off the
smoke-alarms? The only really effective one I can think of is an ax...
(Why must we be constantly plagued by this sort of crap, anyway?)
