I have been collecting times and dates of radio interferance coming in on our frequency. 155.145 licensed to Ralls county. It is our fire channel frequency and this has been an ongoing issue for a LONG time. Who do I talk to to try and isolate it? Just to add it is coming in on mobiles, base stations, scanners.

The last day, I have been able to receive signals from Clarksburgh WV, powerful enough to overide a signal from a class A television station - WTAJ in Altoona some 48 miles away.

The Television station in West Virginia is 120 miles away.

I live near Punxsutawney PA and am using a Winegard 8200U antenna and a Channel Master CM 7777 pre amp and a Channel Master CM 7000 converter box and a antenna rotor.

Stations of mention are - WDTV - channel 5 - 100% signal - 9 AM yesterday.
WVFX - 90% signal all day
WTRF - 90% signal all day
WBOY - 90% signal all day

I saw on the weather map last night that there was a boundry line that was from West Virginia that was reaching up into my part of Pennsylvania and I figure that the weather was bending the radio waves and ducting them into my location. ]]> Skip / Tropospheric Ducting Forum jbantennaman http://forums.radioreference.com/skip-tropospheric-ducting-forum/164695-tropo-ducting-meteor-scattering.html http://forums.radioreference.com/skip-tropospheric-ducting-forum/164498-east-tn-north-south.html Sat, 14 Nov 2009 23:24:59 GMT Getting some short tropo from my Live Scanner feed in East Tennessee Might wanna keep an ear out this evening, Hearing some 200 to 300 mile traffic based on the addresses of calls, sorry no further details I dont know what frequency its on as im at another location.

Of course that's not the only enhanced activity I'm seeing... all of 800 Mhz is ripe right now.

I believe this is the farthest 800 mhz signal I've copied. It's over halfway across the state.

Also copying 712D-015 (Brinkhaven / Knox Co) - but this isn't a first time for this site.

This was the BIGGEST VHF Hi band ducting event I have experienced since I got involved with scanning and radio.

From Pearcy, AR. using a RS PRO-96 with Hustler MRM magmount Antenna at 10 feet AGL-
On a hunch since a tropical blowup was in the Gulf of Mexico, and a cold front approaching, I decided to try a little VHF/UHF searching to see if any ducting was going to blow...
And this is what popped with great to near perfect sound- A couple I identified, most I didn't... The P-25 stations came in as clear as if I was in a patrol car with the deputies in some County in Texas!

This was all between 14:30 CST - 08:00 CST.
As of now - 10:34 Hrs CST am still getting minor ducting. But NOTHING like that night!

Anyone that can ID any of these feel free to do so, I would love to know just how far away they are! ]]> Skip / Tropospheric Ducting Forum milf http://forums.radioreference.com/skip-tropospheric-ducting-forum/164030-huge-ducting-11-07-08-a.html http://forums.radioreference.com/skip-tropospheric-ducting-forum/164009-lowband-open-11-08-09-a.html Mon, 09 Nov 2009 03:03:53 GMT Lowband is now open, I am getting ops on 10 meters SSB and a repeater on 29.580 as well as various PS loband stuff throughout the band.
