Las Vegas NNSA Update

It would appear that the UHF federal trunked systems in the Las Vegas area have gone through some channel changes prior to the narrow banding deadline of January, 2008. Last time I was in the LV area I noticed some UHF trunked channels that were not heard before, and this trip I was able to sit down and analyze some of what I am hearing.

I was only able to grab a few of the sites, but here is what is currently in use:

National Nuclear Security Administration (NNSA) Trunked System
System ID = 7526
Motorola Type II, with APCO P-25 voice

Site 004 - Las Vegas DoE Facility
406.9875 - Control Channel
407.3625
408.3625
409.5250
409.9250

Site 006 - Angel Peak, NV
406.1125 - Control Channel
406.5500
409.3000
410.2500

Site 009
407.3500 - Control Channel

Site 010 - Nellis AFB
407.9875 - Control Channel


It also appears that the Nevada Test and Training Range (NTTR) EDACS system has changed some frequencies around. I was able to copy an EDACS control channel on 406.5625 MHz, 408.0500 MHz and 409.9625 MHz. I have not seen these frequencies listed as part of the NTTR system in the past.

More updates on this as I am able to figure them out...

US Geological Survey

After seeing some requests for frequencies for the US Geological Survey, I decided to post all that I had in my database. These were compiled for the March 2005 Fed Files column. I have included not only land mobile voice channels but also some very narrow band data channels that appear in the federal NTIA assignments.
