Area 51, NTTR and Nellis AFB Trunking Systems


The three trunking systems used for ground communications at Area 51, NTTR (Nevada Test and Training Range), the NNSS (Nevada National Security Site, former NTS) and Nellis/Creech AFB are using frequencies in the UHF band, 380-400 MHz and 406-420 MHz. The systems use two different standards: Motorola and APCO P25. They can be monitored with modern Trunking Scanners, capable of decoding APCO P25 audio. However, the Area 51 mil. air system uses encrypted transmissions. Each system has several repeater sites across the NTTR. All frequencies are in MHz, unless otherwise noted.

03/22/12: System first detected. No activity on system as of 12/28/2012.
Except for Systems 08 and 10 the location of the sites is the same as the old EDACS sites with the same Site ID.
05/29/13: System is active, replaced the old EDACS ProVoice system. Transmissions are encrypted.


System Map

This map of the NTTR shows the locations of the trunking repeater sites of all three systems. The original Motorola system (blue, M-...) is in use within the NNSS while the rest of the NTTR uses the P-25 mil. air system (yellow, E-...). Note E-08 is now E-10. The new APCO P-25 System (blue, M2-...) is used at Nellis AFB and Creech AFB.
