Contrary to the rest of ICAO, In the US 123.45 MHZ is not an Air to Air
frequency. 123.45 MHZ is designated for non-governmental flight
testing. However, a special use authorization is allowed as acceptable;
air to air, for aircraft in remote locations to use it to exchange
operational information and facilitate the resolution of operational
problems. No altitudes are specified.
