Possible AC Line noise

[pastormg]

Yesterday, I entered excessive band noise.  But this morning the band noise was gone as of 7:00.  But now the S-Meter go from 0 up to 7 in spikes.  This is on 12 meters.  Could this be AC Line noise from the powerpole?  I put in a problem request with my local power company and they were very receptive to coming out and check for any problems on the pole.  I hope I did the correct thing!  Mark KB3Z

Have you tried turning off breakers to see if it's coming from somewhere in
the house?

Mark, I had a noise problem too. I just new it was the next door neighbor's
solar panel! With the P3 set to visualize the noise, I went around the house
unplugging stuff. As it turned out, the noise was being generated by a cheap
replacement laptop power supply! It's the old story of out of sight, out of
mind. Gary at Elecraft ALSO suggested using a portable AM/FN radio set to
maximum of the interference and doing a walkthrough. Keep the antenna
horizontal and rotate the direction to find "hot" spots. It works! Good luck

A KX1 works really well for me with the hot wire fences around here.  I
use a Buddipole whip sticking out of the pocket in my cargo shorts, and
just start walking.  I collapse the whip as I get close to lower the
signal, sometimes just disconnecting it altogether.  I've always found
it, weeds growing up or some place where the stock bent the wire into
the fence or a tree.  I made a deal with all the neighbors that I'd just
fix it and not bother them.  Never takes more than a minute or two.  30m
seems best.

If you're going to fix it hot, remember: "Ground end first, then connect
to wire." :-))
