[Elecraft] Possible AC Line noise

[Fred Atchley]

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
