I noticed Lockheed has a pending FCC frequency assignment very close
to the Tonopah Test Range. The frequencies range from 1441.5MHz to
1501.5MHz, which is out of the range of most scanners. Not that you
could demodulate them anyway since they appear to be telemetry, with a
bandwidth of 12MHz if I am interpreting the file correctly. However,
in SIGINT, the presence of these signals is in itself information. If
you detect a carrier, then something should be flying.

popular frequencies in the past for telemetry and  airborne uses , now
also part of the newer (  out for a few years now , deployed since '92
as I remember )  spread spectrum   / microwave  combined data , voice
and video  LYNX  OS  E1  data radio systems.  these  incorporate all
the newer 5  gig and up freqs - bands  with all the older freqs 2 - 5
gigs  , and freqs  like the ones above and the airband ones as well. .
it was a super kewl  all in one all in one radio and data commo system
with all ( or most anyway ) active  airborne and truck borne  radio
nodes being able to act as airborne / field repeaters if necessary.
multi - multi redundancy / expanded coverage .   supposed to be
designed to  also hook up with the  RFID illuminator sat systems and
the  futuristic  lynx man pack stuff if it's ever developed as well.
most likely if they are asking for that frequency range , it's to get
on the newer network radio systems  now  used throughout  many
branches of the government and military.  not much old ( dark ages of
radio ) style carriers  on those freqs these days  digital  .......
or , said in another way, not much for you or I to hear up there .

try looking up the military  lynx operating system, E1 radio systems
and  other current spread spectrum radio systems.  they are 
well deployed in the field, especially in aircraft and UAVs .....
but mostly the systems , their deployment and capabilities are
currently classified and I doubt much info will be available.
