It sounded simplex to me. I submitted it. I was just surprised to hear them using that frequency. I would assume it wasn't in the database because it was thought to be not in use anymore even though apparently it was the main FG frequency years ago. The only reason I had it in my scanner was because it's also the FG for Bridgeport CT. I was in Edgewater when I was listening and the call was on West 66 street on the 14th floor. Most of the transmissions were loud and clear, a couple were a little scratchy. Its very rare I hear any FG communications from Jersey because it is such low power. Ansky, the DOITT system is used for 10-75's whenever the field com truck is on scene. Someone can correct me if I'm wrong but it's basically a patch between the low powered FG frequency to the DOITT system.
