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?)

Thanks,

Ken Gordon W7EKB
