VHF Frequencies

Railroad radios display the transmit and receive frequency as AAR channel numbers. For example, these numbers will be referred to over-the-air as "1616" for AAR channel 16 (160.350) or "1180" for AAR channels 11 and 80 in full duplex use (Dispatch transmits on one channel and the train transmits on the other channel).
