[ICOM] Help with Severe Electrical Noise

[michael morgan]

Ok it has to be something in the shack.  I would think.  Intially my test
was to flip off just the break to the shack and when I did that the noise
went away.  I then flipped off everything but the breaker to the shack and
the noise was still there.  So would I think it was coming from inside my
shack?  I tried to unplug everything in the shack and the noise is still
there.  I am very confused at this point :)

Thanks for all the help.
