The two trunking systems used for ground communications at Area 51, NTTR, the NTS and Nellis AFB are using frequencies in the UHF band, between 406 and 420 MHz. The two systems use different standards. The Motorola System can be monitored with modern Trunk Tracker Scanners, capable of decoding APCO P25 audio. The EDACS ProVoice system can be monitored for activity, but today's scanners are not capable of decoding the transmissions. Each system has several repeater sites across the NTTR. All frequencies are in MHz, unless otherwise noted.

Note: The frequencies for both trunking systems have changed around 11/27/2007. The frequencies below are the new frequencies, after the change. All new Motorola control channels should be in the list. But we are still missing some voice channels, as well as some of the EDACS channels. We will complete the list shortly.

This map of the NTTR shows the locations of the trunking repeater sites of both systems. The Motorola system (blue) is in use within the NTS, while the rest of the NTTR uses the EDACS system (yellow).
