I thanked him profusely for their efforts and he told me to call him directly whenever I have a noise issue.

They have been out "hunting" but so far have found nothing - looking for needle in a haystack - he tells me.

The only thing I can tell from my station is that the peak is just about North of me swinging the beam around. Strongest on 20 meters, CW portion. I can still hear it on 6 meters but not as strong.

> I just picked up this message on the thread and didn't see where it originated but the recording that I just played is most definitely power line noise. By that I mean it's being generated by your power electrical utility outside of your home. If you want to call me for further information or instructions or points to ponder just give me a call if I don't answer your call please leave your phone number. I'm on the phone a lot and traveling a lot. Best wishes
