Actually, all that info was on the page Hank quoted. Here is the definition of Tie-In.
1-2-10 Tie-In Facility
The ‘‘FAA TIE-IN FACILITY’’ is the telecommunications facility that handles flight plan messages for the listed landing facility or navigational aid. This also applies to Canadian facilities. Tie-in facility hours are local times. The absence of a facility in this column indicates that the location identifier is being reserved for the future commissioning of the landing facility or navigational aid.
There are navaids that exist that are not documented, namely
MCY VOR at Groom Lake
PYD NDB near Groom Lake
XSD NDB at the end of the TTR
AEC NDB and VOR at basecamp

Note there is a real MCY NDB at DRA. All the frequencies are on the DLR list.

If you want to learn about more undocumented navaids, you need to search the scanner or shortwave related lists and websites. Due to their range, undocumented low frequency beacons have more of a "following."

Speaking of radio signals around the range, there is some telemtry, much not documented. Anytime you have a large facility, there is telemetry for tank levels, freezer alarms, etc. I catch a signal when bandscanning, park on it, and you never hear it again in the next few hours. One exception is 411.2Mhz, which goes off every 15 minutes or so at the TTR.

The test aircraft themselves have telemetry, aka "music". These signals are probably in the higher frequency federal band, maybe the 1700 range, which some scanners cover. I think the next range is around 2500Mhz, beyond most consumer gear. You can find experimental FCC licenses for such gear if you search the database around Nellis. The licenses go to military contractors, not the military, so they are not in the classified portion of the IRAC.
