Here are a few recordings of radio beacons around Area 51 and TTR. As of 2019 all HF NDBs except for the Basecamp NDB are no longer active. Modern guidance systems such as ILS and RNAV approach have eliminated the need for these fixes. Basecamp is not ILS equipped, so the NDB there is still in use. The VOR fixes are still operational.

	Beacon	Notes
	Area 51 VOR	117.500 MHz; recorded 08/07/2005 around 7pm on Tikaboo Peak. Weather report and morse code identifier "MCY" (for Mercury?). Notice that the weather report only says "local" for the location.
	Area 51 VOR 2019	117.500 MHz; recorded 02/06/2019 around 2pm at the Powerlines Overlook. Still the same format as in the above 2005 clip. Still only says "local" for the location.
	PYD NDB	414 kHz; recorded on Wednesday, 3/30/2005 near the Nye County line. This NDB is probably located in the valley north or north-west of Area 51. Only morse code identifier "PYD", no weather info. This beacon may be the fix "Pyramid", which is frequently used in flight clearance transmissions for Janets from LAS to Groom.
	TTR VOR	113.000 MHz; recorded on Thursday, 3/31/2005 around 2pm from a TTR view spot along Hwy 6. Weather report and morse code identifier "TQQ". The weather report identifies as "S1", not TTR. Mentions that runway 32 is in use, and the live fire range is "cold", ie. closed.
	TTR VOR 2019	113.000 MHz; recorded on Thursday, 03/07/2019 around 1:30pm from an elevated location near the TTR main gate Weather report and morse code identifier "TQQ". The weather report now correctly identifies as "Tonopah Test". "Runway 14 in use, runway surface condition dry, bird watch condition low, live fire cold, Sandia airspace hot"
	TTR ILS-14 Localizer	ILS Rwy 14 localizer beacon (I-RVP), 108.300 MHz; recorded on Thursday, 03/07/2019 around 1:30pm from an elevated location near the TTR main gate; morse code ID "IRVP"
	XSD NDB	278 kHz; recorded on Thursday, 3/31/2005 near the TTR main gate. This NDB is located north of the TTR airport, in line with the runways. Only morse code identifier "XSD", no weather info. It was reportedly set up before 1980 by Sandia Corp.
	Basecamp VOR	113.900 MHz; recorded on Thursday, 3/31/2005 near Basecamp. No weather info, only morse code identifier "AEC". This VOR is not always on (!) The ID is a reminder of the time when Basecamp was established by the Atomic Energy Commission (now the DoE) as base camp for the underground nuclear tests in that area. For more info see our Basecamp article.
	Basecamp NDB	209 kHz; recorded on Thursday, 3/31/2005 near Basecamp. Same morse code ID as the VOR, but with weather info and station identification as "Basecamp".
