Las Vegas NNSA TRS Updates?
I am seeing posts over on Radio Reference that there may be changes afoot for the Las Vegas area UHF trunked system operated by the National Nuclear Security Administration (NNSA). Until recently, the NNSA operated the wide-area UHF trunked system that was utilized by Nellis AFB as a subscriber agency.
Now reports are that a new UHF trunked system has come on the air, using the System ID of 00F, NAC of 00F. Site 1 is reported using these frequencies:
406.5000
406.7875 CC
407.1875
407.3000
407.5000
407.8625
408.1500
408.9625
409.1125
409.5625
409.7125
410.6500
Some replies indicate that this new system is a separate system for military use only and that Nellis will no longer be a subscriber to the NNSA system,
If anyone in the Las Vegas area can keep me posted on this change, please send them along to The Fed Files.
UPDATE:
I took a look at the frequencies that have been posted as part of this new "000F" trunked system and see that most of them were part of the NNSA trunked system site 10, that was assumed to be located and service Nellis Air Force Base. 410.6500 MHz, was logged with some activity in Las Vegas a while back, but was not part of the NNSA system as far as I could tell.
So I'm wondering if Site 10 of the NNSA system is still on the air on any frequencies? They might have migrated the Nellis site off to it's own system, since it was probably the busiest site in the NNSA system.
There was a post on Radio Reference that indicated this was a move towards providing common trunked systems for Nellis AFB, NAS Fallon and US Navy carrier operations. Not sure if this makes any sense, but I have no information on this change as being part of any larger Navy system.
