[RFI] GFCI

  Well I had originally joined the reflector to get help dealing with 
some power line interference but seem to have a different problem now. I 
put an addition on the house including a new garage. Each wall of the 
garage has it's own circuit which has a GFCI to protect it. I have 
finally gotten to wiring the last wall. I find that the GFCI is tripped 
occasionally. I have spent the last month trying to figure out why or 
how it gets tripped. Apparently when I am transmitting on 30 meters the 
outlet picks up that tx and sounds like an old railroad telegraph 
sounder from a western. This wouldn't bother me too much except that the 
addition was put on for my mother to live in and her head is about 5 
feet from the outlet on the other side of the wall while she sleeps (no 
she is not interested in learning code).

I have 2 other GFCI's in the garage and 2 more of the same units in the 
addition of which none exhibit this problem. Do I have a bad GFCI? Is 
the Romex running from the service panel to the outlet resonate on 30 
meters? I could add a junction box and some extra wire to the circuit if 
folks think that would help. Just looking for ideas before spending 
dollars on things that don't work.

Thanks
Phil
