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.

I have a portable general coverage RX that might help you track the problem down.

Re: Hunting Down RFI
开云体育Forgot to mention, no noise on rig w/o
antenna, so I don't think anything is coming on the AC line.

Hunting Down RFI
开云体育
Just wondering if anyone has any tools/tips for hunting RFI.? Lately I have noticed S9 noise levels on some bands, though the noise appears
to be very wide-banded.? It is quite evident in the spectrum display when it is present, and seems to cover hf to 6 meters, but worst around the 10Mhz band.?
It will to last for hours and then maybe go away for hours, but when it is present, it will occasionally stop for a few seconds and then start back up.? I seems likely to be a power line arcing issue.
On my AM car radio, it seems to be worse both east and west of my house for maybe a ? to ? of a mile.? Hard to know for sure, as I only have the sound to judge.
I did try walking around with a HT at 137Mhz AM and a 2 meter 3 el yagi, but not much luck, or I didn't go far enough.
?

I'm back on the air.
I had been inactive since last November, but a few weeks ago I bought a new base radio FT-991A. ? Set up a 2M/70cm antenna and an hf antenna (finally an outdoor hf antenna). ? In the very early hours I play on HF, later in the mornings I check my Winlink mail, and then I check in on the east coast reflector (WR2ROC), and talk on N2HJD-R, ?then most of the day I'm monitoring 146.44, and have an Echolink link node on that. At my current antenna height, I can reach from my location near LongPond and English over to Lake and the Parkway, over to the Parkway and Manatou, and then as far south as Ridge Road. The node might serve for VHF operators in that area to make more distant contacts.
?
On the road, I finally got my TM-V71A installed in the car with a decent antenna, ?One side of it is monitoring 146.44, the other side is to talk on local repeaters.
?
I gave up on APRS. ? The coverage is not good in Greece from the car, so I only get position reports through if I drive into the city. ? I still have an FT5D, that can do APRS if I'm ever in a situation where that would work.

Resend: Amelia Earhart and Radio Direction Finding
开云体育
Sorry if you get this twice. There seemed to be an issue with the original email.
There are have been many books and documentaries about Amelia Earhart over the years, but this one includes some detail about radio direction finding as a navigation aide, including a demo of using loop antennas. You may find it worthwhile to view.? It is from the Veritasium YouTube channel
