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.

Well it is not meteor scatter as that is a very short duration event which could range from less than 1 second to about a few seconds or possibly a little longer.

Strong weather fronts can definitely cause VHF/UHF propagation. Inversions in the summer are almost a guarantee of a band opening as an example.

Exactly how it all works, I'm still plugging through that, but I am growing to really like 2m and think I'll be putting up a fairly serious antenna for it at some point.

TV Ducting

Thought things were strange when I was having a problem getting my local broadcast stations, the digital channels were breaking up so I turn my antenna to the northeast and did a rescan and was getting a few that were far enough that you should not be able to receive.before I list them let me tell you where I'm located, I live 30mi north of Tampa Fl and my antenna that I have is an older model from radio shack, I don't remember the name but it wa the 180 model for vhf/uhf and a pre-amp with it. hope that helps. ok here is what I got on Monday eveing. if anyone would like to see the photos I took with my camera jusk ask and I'll upload them.

Digital is a all or nothing proposition.

Either you have a perfect picture and sound or you have some sound and pixelation or you have nothing at all.

Very true, it's there or it's not. since CH-6 WKMG in Orlando have reduce there power I can only receive them during the eveing hours since they are running only 944kw. if you want to look up your local stations a good site to look them up is at this url. TV Fool

I don't think you can have an appreciable meteor scatter at UHF. It's best @ @ 50 mhz and drops as you go up in freq.
