    Not a huge deal - really found money, if you will.

    I had a set of powered rabbit ears that I hooked up to my new Samsung plasma. I am about 40 miles north of Atlanta, and I wanted to see if the rabbit ears would simply pick up Atlanta channels. I have really struggled in the past pulling in OTAs, but I haven't really tried in the past year or so - not a huge need.

    Well, I went through and scanned, and I pulled about six channels of which I didn't recognize the call letters. So, I googled the results and I'm getting multiple channels (e.g. 15-1, 15-2, 15-3) from places like Montgomery (AL) Birmingham, Chattanooga, and Huntsville (AL). What makes it even more interesting is that I got nothing from my Atlanta channels. The cities I hit are from as far as 200+ miles away.

    Now, I have a pretty good idea why this happened as far as hitting channels that aren't local and not hitting the ones nearby - the power is too strong to hit the locals. I get that part. I guess I'm just stunned by pulling in channels from hundreds of miles away!!!

    Did the digital transition have anything to do with this? Any thoughts anyone?

    Thanks in advance!

    Below is a message from the Houston OTA forum at AVSForums. The tropowhatever may be involved in your case.

    That link is giving me a "broken link" message. Not sure what this means...

    Let the record indicate that I have rescanned, now that it's dark, and I am no longer getting the channels in AL and TN that I was getting earlier. Also, I am still not able to get any local OTAs other than one that is broadcast very near where we live.

    I couldn't get that link above to work, but reading what I was able to understand from Olguy sounds like the premise behind the movie "Frequency." :)

    "Frequency" is one of my favorite movies (so is the "Back to the Future" trilogy). While not bending time"Tropo" ducting bends radio signals and makes for interesting viewing, but you can't count on it for daily viewing.

    If you want to get your locals, you may need an outdoor antenna, or at the very least an indoor antenna properly aimed out a window that faces the direction of the local stations.

    Every spring and fall, early morning, late evening, the atmosphere becomes tiered in a way as to cause VHF and UHF terrestrial television stations to "duct", i.e. they enter the duct at the horizon to the transmitter, and are carried very close to the ground, as opposed to their normal behavior, which is to fly off into space in a direct line. When they happens, you will be able to get increasingly farther and farther station, depending on how widespread the duct is, and in which direction. In some cases, the signals in the duct will be stronger than the local transmitters signal level at your location, causing the distance station to override your local station.

    In the past two weeks, from Central Arkansas, I have picked up TV stations from Panama City, Florida, all across the gulf coast to Houston, Tx, and over to San Antonio. Its been a very active spring. The following website will show you the current conditions of ducting. If your location falls within a big red blob, you should be able to receive tv stations from within the same red blob.


    For predictions of future ducts:


    For Forum of TV DX nuts (those of us that actually spend money trying to see how far away we can pick up tv stations:
