Re: Hunting Down RFI
开云体育Thanks for the offer, I'll let you
know.
It is interesting to watch my spectrum
display, sometimes the intensity of the display will lower, but
signal still at S-9.? Then occasionally it will suddenly go quiet
and s meter will start to drop, then immediately start up again.?
The way I see the display fluctuate pointed me to a power pole
issue.
I put my FT-857 back in the car and
drove down the road and saw a definite peak about a quarter mile
west, monitoring 20 meters with a hamstick on the roof of the
car.? I tried my HT at 136.7500 AM, walked down the road to that
area, and using my Arrow 2 meter yagi, found a peak on a pole.?
Strangely, it was not a pole with 14KV, but just a Ginna warning
siren pole.? But it peaked pointing right at the control box
mounted on the side.? They do have a small vertical higher up, so
there may be a transmitter in there, but not peaking where the
antenna is higher up.
So not sure if the s meter peak I'm
seeing is the noise or some other RF.? The audio is definitely
noisy there, and the area where it peaked with the FT-857 whilst
driving by.? HF might be better if I can get a loop or something
directional.
I watched W4DD's video presentation.?
His RFI Mapper looks interesting.? If I can get that working with
my 857 easily, I might try it.? I might also throw together a 3
element yagi for 137MHz.
I can't find a specific number at RGE
to report RFI, so I'll probably wait until Monday to get a real
person.
