[RFI] Strong, broadband noise during wet conditions

[Eddy Swynar]

Hi Guys,

I had just the opposite thing happen to me here a few years ago, i.e. the power line noise only stopped whenever it'd rain outside!

Turned-out that it was the power drop-off switch off of the main line feeding my next door neighbour here in the country: it was ancient & all pitted & black, & arcing---but when the WX was wet, the arcing stopped.

Anyway, the power company installed a brand new switch, & all was well...

I just need to wait for conditions to get wet again, then I'm going to do the breaker-off test at the house and go for a drive with the 706 to see if I can narrow down the source.

At my previous QTH I could count on the high pitched buzz any time it rained or snowed or even in super heavy fog. I had both a 1/2 mile away 100KV and a mile away 380 KV and they both just howled when wet.
