[FedCom] US Marshals Service Freqs & Ops

[Ken]

Another interesting agency is the US Marshals Service.
For locations of these activities click on the appropriate state map at:
http://www.usmarshals.gov/district/index.html

Additionally, if you go to the "state page" for each district in most 
instances there's a list of "Local Law Enforcement Task Forces" that USMS 
participate in, which varies from state to state.

Grove's "Federal Frequency Directory", 2nd edition with search term 
"Marshals" gets 26 potential listings.  UHF wise 10 simplex & 3 repeater 
pairs are listed.  Additional 13 VHF highband freqs are listed.

Tom Kneitel's "The 'Top Secret' Registry of U.S. Government Radio 
Frequencies" 8th edition (1993), lists VHF highband consisting of the 
following:
Marshal's Services
* 3 Repeater pairs, categorized as "City Repeaters", "Administrative & 
Operational Repeaters", "Border Area Repeaters"
*3 Simplex Frequencies
Court House Operations:
*1 frequency pair "Operational Repeates"
*2 simplex frequencies

USMS may also use regional law enforcement coordination net frequencies 
(either through loaned portable equipment or when feasible programmed freqs 
in their mobile units).   A recent short lived series on "The Discovery 
Channel" showed USMS as primarily using cellphones & what appeared to be 
nextel nationwide w/t's to coordinate initial investigative functions & 
response & than switch to USMS radio systems when at "on scene" surveillance 
& tactical apprehension activities.

Perhaps low powered simplex ops overall makes this federal activity 
difficult to monitor.
