[FedCom] Las Vegas UHF Mysteries

[Chris Parris]

Been working in the Las Vegas, NV region this week and have found a  
few UHF frequencies that I've had trouble pinning down who the users  
are. Thought I would throw them out to the list and the blog page and  
see if I could get some input...

407.3250 MHz, D051 - Security operations. Might be related to  
activity on 407.5250 MHz (see below). This frequency is allocated as  
a federal Itinerant local use repeater.

407.5250 MHz, D023 - Definitely sounds like a military security net.  
I've thought it might be Nellis AFB, but this analog repeater does  
not seem to be patched to the NNSA UHF system the rest of Nellis  
seems to be using. The frequency is allocated to various DoD services.

409.0250 MHz - This frequency started showing an EDACS control  
channel. It is showing that it is LCN 3 of Site 7, so I am guessing  
it is part of the NTTR (Nevada Test & Training Range) trunked system,  
although this frequency has not been listed as part of this system in  
the past. Changes in the UHF channels may be showing up in the local  
trunked systems as well.

409.3000 MHz, P-25 - This seems to be a stand alone P-25 repeater,  
but everything on this has been encrypted so far. This frequency is  
allocated to various agencies, including the Department of Energy as  
well as DoD.

415.5750, D754 - Another security operation, but definitly NOT  
military. Very "civilian" radio procedure. The frequency is primarily  
allocated to the Department of Agriculture, but also has some NOAA  
and US Postal Service allocations.
