(*) = limited activity on this frequency

"COTHERN" is "Customs Over The Horizon Enforcement Radio Network".  It
consists of 10 channels with digital SELCAL tones (bleeps) which are
scanned by users and used to "handshake" connections between individual
units and determine propagation.  These are the PRIMARY US Customs HF
frequencies.

"Return to Scan" indicates the units are through with the specific
call and are switching their radios back to scanning the 10 COTHERN
channels for general calls to their unit.

An "Air Operations Base" is a primary station, while "Air Operations Unit"
is a secondary location.

A "Sector Office" is the primary controller for GROUND units in a given
part of the country, operating remote transmitters on VHF at multiple
sites in its controlled sector.

Air units are controlled by one of the C3I stations, either East or West,
with a Central C3I station under construction at Oklahoma City, OK.
