ICOM IC-M504A VHF Marine Transceiver

The IC-M504 is a compact, rugged VHF radio built for the harsh marine environment. Not only is the unit waterproof, it is submersible for up to 30 minutes at a depth of 1.5 meters. The IC-M504 has a 168-charactor, full-dot matrix display that allows you to easily view a variety of information, such as GPS data, DSC emergency data, etc. The large buttons and knobs provide user friendly operation. The IC-M504 has built-in class D DSC, which enables you to constantly monitor channel 70. This functionality provides users at sea with the peace of mind that they can call for help by pressing the "Distress" button if the need arises. Over and above the DSC, your own and other ships' position data can be exchanged with the position request or position report functions.

The IC-M504's superior receiver provides excellent resistance to intermodulation and allows you to catch a weak signal between strong stations. The extra large speaker is mounted into a well spaced housing, producing greater sound than the specified 4.5W output power. You can get clear and loud reception without requiring repetition of the message, even over the engine or other background noise. When connected to a hailer horn or external speaker on the deck or tower, you can make an announcement on-board from the microphone. The RX speaker function, "receiver-repeater", allows you to monitor the received audio. Four foghorn patterns are also available for the automatic foghorn. The COMMAND MIC-III is a remote control for the IC-M504 that may be positioned up to 60ft away from the radio. All M504 functions, including distress call, DSC, and foghorn, are available. The COMMAND MIC-III may also be used as an intercom with the IC-M504. The M504 features Dual/Tri Watch and full scan functions, NOAA weather, and an optional voice scrambler. Includes radio, power cord, and mounting bracket.
