Default Backpacking antenna question (Was: Test)


wrote in message
...

I can "feel" when I'm in a high RF environment. And I seem
to be effected more by lower frequencies, than I do high.
I've "felt" RF at home once when running 160 meters with
a antenna fed from the shack.
And I've also felt it when running mobile, with the antenna
behind my head on the trunk lid. This was noticed when
running CW on I think 80m if I remember right.
And I have no pacemaker, etc, and was in normal health.
I didn't feel pain per say. It made me feel nervous and
uneasy. Hard to explain really.. But it definitely would
start and stop with my sending. It took a while before
I realized what was happening, and then I tested it with
sending tests. Sure nuff, every time I would start sending,
I would start feeling the effects. Quit sending, and it would
go away.
This was with a plastic bugcatcher mounted on the trunk
lid, with the loading coil just above roof level.
Running 100w CW. I've never really noticed it using SSB.
Too sporadic I expect, where as CW is pretty much pedal
to the metal when actually transmitting.

In both cases, I was near the current maximum. At my
table in the 160m case, and beaming the back of my head
in the car.


I'm sensitive to static charges ... at least I think so. In 1972, I
taught a course for technicians working on high-speed Xerox
Telecopiers, a run-up to todays FAX machines. It was called
LDX, which stood for Long-Distance Xerography.

When I was around those machines, which used multiple
static charges to form the images, I was always nervous,
anxious and jumpy. I recall an odd smell, similar to the air
before a thunderstorm. (ozone?) I never had the same
feelings in the classroom, so I'm fairly sure it was the
effect of those machines.
