They had an analog 800MHz repeater at the airport that broke. Now I think they are just using simplex. You should hear them here if you have a big enough antenna and/or are close to the airport.
One other quick question is the airport fire dept on the same freqs or are they on a different system I dont see anything for them on the data base so I was wondering if they maybe were run by the Columbus Fire Dept?
Fire and security are both using the freqs listed above. They have some radios that are programmed to tqlk kn the Columbus 800 system for interoperability, but the airport operates on simplex.
