Hi Jerome
Can you post a WAV file to the website?
Try emailing Clint KA7OEI - is address is at http://www.ka7oei.com/email.html
I had (and still do have) a problem with some sort of power line discharge type
noise from HT power lines near our house. It's a sort of 50hz based spark type
noise arranged as if it's three phase but there's a
pulse-pulse-gap-pulse-pulse-gap patter which makes me think it's a 3-phase
delta wired device with a crapped out insulator. I never did find it, so tried
building the line synchronous noise blanker that's on Clint's website. (It
didn't help BTW)
Clint knows a lot about this stuff and may be able to analyse a wav sample for
you.
Alternatively download a copy of cooledit pro from bit torrent and analyse the
waveform - it may give a clue
Hope this helps

Here's the admittedly weak connection between my Amplifier and my 30M
receiving noise problem: The noise coming NOT from my trusty old 813's,
but somewhere else, is so bad it makes no sense to use the Amp as I
can't hear weak returning signals through the noise.
I know it's a stretch, but there is such a rich collection of talent on
this list across so many fields, that I couldn't resist tapping into it.
If you care to have a look, there are three spectrum scope photos of my
30M noise along with some verbiage that describes the situation.
http://www.ehpes.com/noise/noise.html ; will get you to the photos.
Thanks for any ideas about what the culprit might be!
