The shock one would get under such circumstances was one of the reasons
that early studies into the effects of HV AC lines were flawed. I believe even
Brodeur's work cited this erroneous work. Apparently, the studies included the

I have never had any personal experience with HVDC but I do have a

I just twist my wires in a

solder. If I get really sophisticated, I slide a piece of copper pipe over
the twisted area, crimp it, and flood the whole inside with
You don't step off a combine when harvesting under HVAC lines. You learn to

I think it is capacitive coupling. The larger combines pack a real wallop

Hi James,
Thank you for the hint. I read the article, and I see t's a very good
solution. For the moment I can't install this elevated FCP.
I have to mention my soil is good, quite wet most of the winter.

You didn't say how long the horizontal portion of your inverted-L was. If
we knew that, that would help us help you. :-)
FWIW, W1BB himself said that an inverted-L could have a vertical section of
only 25 feet, and still be worthwhile.

I’ve also posted this on the RFI reflector.
I’m hearing a peculiar RFI tone on 160m and 80m. It’s two tones. One is a long
tone with a short OFF. The other is approximately 13 kc lower and is ON exactly
when the first tone is off. Sometimes the second tone appears plus and minus 13
kc from the
Since getting the new 630m band (472-479KHz) here in Canada, one of my
favorite ways of promoting interest in the new band has been 'crossband'
activity ... that is, transmitting on 630m while the other stations transmit
on a predetermined announced HF (QSX) frequency, usually on 80 or 160m.
I've been ham since 1969 and there has always been a issue with DQRM.

Yes, it has been with us a long time.

Those Hammy Hambone radial plates I have seen advertised are considerably

Don,
All good points. A few weeks back, there was a discussion here about the
virtues of using MAPP gas or acetylene with silver brazing rods.
