Hi Ed,
thanks for the reply. I don't have any really bad line noise right now.
After I went in person to the city electrical dept. (I think showing up in
person is better than a phone call) and talked face to face with one of the
power engineers I got a phone call a week later telling me they found some
poles near my house that lacked "noise supressors" which I have never heard
of, and which they installed. That was back in the summer. I waited for
fall with cooler wx, and alternating damp and dry condx to see if the noise
would return and it hasn't. I guess that did it or else it went away by
coincidence. I'm getting minor intermittent appliance type noise now which
I think is from my neighbors. Now that I'm reasonably sure the power pole
noise is gone, I plan to write a thank you letter and copy the dept. head
and maybe the mayor.
But back to the ultrasonic rx--so I don't need it & can wait for your guy to
try it. I hope you do a short writeup in QST. Maybe someone else could give
it a try?
Tnx & 73,
Rob Atkinson

It definitely heard ultrasound, but the fellow we had here working on
power-line stuff never did take it out and listen to a few noises. Our new
RFI guru, Mike Gruber, W1MG, has it on an ever-growing list of things to do.
I do have it here, and if you have a very strong local source and want to
give it a try, I can ship it to you, if you promise to give the list a
report!
