* denotes Atlas frequencies.SLINGSHOT - Combined USCG/USCS Interdiction Center, Miami, FL.            Acts as the nominal command and control for all anti-drug            airborne tracking/surveillance and seaborne interdiction            operations in the southeast US, Bahamas and the Caribbean.OCEANSIDE 300 - USCS/USCG-Blue Lightning Operations Center, Miami.                Coordinates routine stop/searches of small pleasure craft                in the coastal SE USA and Bahamas (carried out by a fleet                of USCS boats).HAMMER - USCS/USCG command and control center, Riverside, CA.PANTHER - The only DEA station normally heard on Customs Service frequencies.ATLAS - Rockwell-Collins Comm facility, Cedar Rapids, IA, which acts as a        "switchboard" for the DEA. It is NOT a DEA Comm station. Atlas         also provides services for elements of the US Military. Almost all        Atlas comms are of a routine administrative nature (Air guard, phone        patches, etc.). Actual DEA operational comms are in secure modes and on        frequencies (unknown) other than used by Atlas or Customs.NUMBERS in parentheses are:
 US Customs Service primary COTHERN (Customs Over The Horizon Enforcement  Radio Net) channels.  The COTHERN system is a digital controlled scanning  system, units send a control blurp of data every so often on each channel  for propagation test and ID, and when a unit wants another unit online, sends a digital selcal on each channel until it finds a response of good quality.  The units then stop scan on that channel and begin USB voice comms.  If they want to scramble, a TDM (Time Division  Multiplex) scramble is used. You will be able to tell if there are units receivable on a channel that you are listening to by hearing the "buzzing" sort of data beeps that the units send occasionally regardless of whether there are voice comms going on.  When a communication is finished, you'll hear the units say they are "going back to scan". [Thanks to Skip Sanders (N6IMN) for the info on the COTHERN freqs.](+) Indicates frequencies which carry periodic data bursts which differ     from those heard on the COTHERN frequencies.The frequencies in the X-ray designator sequence are (according to the Grove Shortwave Directory [4th ed.]) assigned to the FBI for a RTTY/USB network using tone encoded squelch. I assume the frequencies are either "on loan" or have been reassigned to the USCS.
AMBUSH - A military base, possibly in Puerto Rico.CONDOR - Military base somewhere farther south of AMBUSH.ANGRY WARRIOR - Possibly March AFB, CA.VIEWFINDER 2 - Howard AFB, Panama.(#) Indicates frequencies heard carrying morale phone patches.Comms between CONDOR and ANGRY WARRIOR are regularly heard on 14443.0(Yankee Foxtrot).Comms between ANGRY WARRIOR and VIEWFINDER 2 are regularly heard on theSierra Zero X, Sierra One X, and Sierra Two X series of frequencies.==============================================================================
