[FedCom] US Marshals Service Freqs & Ops

[Dave Stewart]

I believe it depends on the area.  In several areas where agencies
have trunked systems, Marshals are able to lease radios and the use of
that trunked system, especially when there is the ability to have
their talkgroup encrypted.  It just makes sense that you could have
one radio for operations, and that also allows you to switch over and
talk to a PD or SO dispatch.

In OKC, 163.200 (repeated) & 164.600 (simplex) are used primarily by
the Metro Fugitive Task Force (both in analog, no P25).  146.2, 136.5,
and CSQ are all used.  163.200 is used to run checks on plates, ask
for someone to look up an address, or for notifying other agents that
something might ramp up ("hey, I think my guy just showed-up...if
you're not busy, let's stage at that Conoco near his address").
164.600 is used at very low power (2-5 watts) for surveillance and
coordinating between 2-3 units traveling together.

I believe nextel is used most for day-to-day USMS operations, outside
the Metro Fugitive Task Force.

170.75 P25 is used for Court operations.  I also have 162.7875 in my
scanner for Court ops, but I can't remember the last time I saw it
used.  Not saying it isn't used, just that I don't recall seeing it
recently.

I've never seen any of these 4 freqs encrypted.

As you may know, the "CONAIR" hub facility (Federal Transfer Facility)
is located on the grounds of the Will Rogers World Airport in OKC.
It's located on the West side of the airport grounds.  A fairly
low-power 400MHz trunked system is in use there. This facility is
operated by the Federal Bureau of Prisons.  You can find more info
about the system in RadioReference at -->
http://www.radioreference.com/modules.php?name=RR&sid=3519, and about
the facility at the Bureau of Prison's Web site at -->
http://www.bop.gov/locations/institutions/okl/index.jsp.  I've never
heard anything outside normal "prison talk" (BORING!!) although I've
never listened when an aircraft is arriving or leaving.
