I'm tracking a power pole near my QTH that is generating RFI from 15m on
up. With a combination of HF and VHF antenna, I'm pretty sure I've
tracked to the correct pole. This pole is generating more of a
"cracking/poping" form of RFI rather than a constant arc like RFI.
I recently built an Ultrasonic detector as an additional tool in my bag
- it seems to work as I can hear tire noise, rubbing fingers, rat
repeller etc... BUT...
When I check out this pole, I can't hear anything ultrasonic wise.
So my question...
Does a power pole generating RFI ALWAYS generate ultrasonics that are
strong enough to be heard from the ground?
Thanks!
