Forgive me of my ignorance when it comes to monitoring Aircraft as I'm a long time communications hobbyists- simply haven't spent much time monitoring aircraft traffic. In the past have limited my Aircraft monitoring to our local airport @ 122.8 Mhz, with the exception of the few years of my youth when I was in the Civil Air Patrol and was director of communications for our "squad" so took the FCC test and held a FCC radio Licence for a year or so, goes w/out saying Never went anywhere with the whole CAP thing other than getting to fliy around for free a lot and play with radios I truly didn't have much business playing with.. Back to point- live in North Central Alabama, in the rural community of Cullman County, have a nice outdoor omi antenna setup and was searching the aircraft frequencies today and have come across several w/ steady traffic and for most part are all extremely high strength signals. After looking at a map I do realize that where I live is extremely close to the dividing line of the Memphis zone-ZTE & the Atlanta zone-ZTL. One @ 120.025 Mhz I'm receiving both sides of the traffic theses are planes referencing Nashville, Atlanta, and Memphis- a sample of one of the one sided communications would be something like:"Good day Delta 7 2000". Then sometimes you'll here a controller talking back and forth with a pilot? Another frequency I'm getting a lot of this on is 133.175 Mhz most all of these are one sided and seem to be related to KATL and about how each plane is clear for "raftor-sp?"Another @ 127.375 Mhz and is mostly relating to Memphis? I've researched these frequencies and can't find them linked to anything that makes any sense to me, and one of my main questions would be why are these signals so strong, I would guess these ATC towers go through repeaters every so often so they can always maintain communications or are there radios just that powerful as that's a lot of airspace between- for example the Memphis and Atlanta zones, and if so why don't any of these frequencies match up to any of these airports?? Any information would be appreciated- Thanks, J. Clarke
