141. [RFI] High local noise level... (score: 1)
Author: "Kenneth G. Gordon" <kgordon2006@frontier.com>

Today, I connected the audio output of my transceiver, a Yaesu FT-890, set to AM-wide, tuned to 3580 KHz, into my computer and fired up Spectran. Spectran is exhibiting a very wide-band series of pea

If this is so (and I am NOT arguing with you about the need for better bonding) why is it that my noise disappears when I disconnect the antenna? Ken W7EKB ___________________________________________

Sounds to me like an arc associated with the power-line somewhere nearby. You'd probably better get a small AM radio and track it as soon as it rains again. Ken W7EKB _______________________________

So, now I have a "new" one...at least for me. Some sort of weird-sounding, very unstable raucus oscillation sound. Appears about every 12 kHz from 7002 kHz to at least 7350 kHz, although that is as f

Sounds like it. Yes. The voltage is something like 2KV at a LOW and 5KV or more on the other end. You most certainly should have felt something. THAT is not correct: according to everything I've see

There you go, Mike! An excellent reason to tell your neighbor that you hear his fence: that any time you can HEAR it, that means it is shorted somewhere and its effectiveness is nil. This is another

Ah! I was not aware of that. I have been around horses who avoid fences that are off, but never cattle. Thanks for the correction. Well, I don't see how they can be. I think that brochure is wrong in

OK. I just checked the manufacturer's site. The specified voltages are: 11.5 KV when the entire fence is "open circuit" and 2650 Volts at 500 ohms. even less at another. 300 Volts, if that is an accu
