How an AM radio works:
This chapter summarizes the major components and principles of radio systems.
AUXCOM, the Auxiliary Communications Specialty course, focuses on radio communications for the Auxiliary and Coast Guard, providing broad knowledge of the fundamental principles underlying communications systems in use by both the Coast Guard and the Auxiliary. You can achieve success as an AUXCOM Specialist by passing a closed book, proctored examination with a score of 75% or better.
Auxiliarists owning or operating Fixed Land, Land Mobile, or DF Radio Facilities must complete the Auxiliary Telecommunications Operator Personal Qualification Standard (TCO PQS) training or must have completed the Communications Specialty (AUXCOM) course prior to 1 August 2008.
This web page was developed to aid the trainees enrolled in Division 22's AUXCOM course. Offered below is supplemental information, which is not intended to replace the course manual.

Making a distress call on a VHF-FM radio:
This chapter summarizes the most significant rules which should be familiar to all licensees and operators of voluntarily installed ship radiotelephone stations. It covers the regulations and procedures all boaters (non-USCG) need to know about using the radio.
Radiotelephone required for:
(1) Every power-driven vessel of 20 meters (65') or over in length while navigating;
(2) Every vessel of 100 gross tons and upward carrying one or more passengers for hire while navigating;
(3) Every towing vessel of 26 feet or over in length while navigating; and
(4) Every dredge and floating plant engaged in or near a channel or fairway in operations likely to restrict or affect navigation of other vessels except for an unmanned or intermittently manned floating plant under the control of a dredge.
Single Side Band vs. Conventional AM
Principal types of radios on boats:
SSB-AM (2-30MHZ)
Used extensively on offshore vessels
150 watt transmission power
Range 100 miles+, greater with skywave bounce
Notable frequencies:
2182KHZ - distress
2638KHZ- ship to ship in all areas
Used for data transmission
VHF-FM (156-162 MHZ)
used for coastal vessel
25 watt transmission power
Range up to 25 miles- limited by radio horizon ( Nautical miles =1.23 X Sqrt (antenna height in feet))
Notable channels/frequecies:
16 (156.8MHZ) - distress/calling
09 - non-commercial boat calling - alternate calling channel
70 - digital selective calling
13 - ship to bridge, or ship to ship
