Position Request and Position Report Over and above the DSC, your own and other ships’ position data can be exchanged with the position request or position report functions. The received position information can be transferred to external navigation equipment*. In addition, the polling (request/ reply) function checks whether a specific ship is within the communications range. * External GPS receiver and navigation equipments which accept NMEA 0183 format are required. Superior receiver performance The IC-M504 has excellent receive specifications of 80dB (typical) for intermodulation rejection, adjacent channel selectivity, and 0.22µV (typical) high sensitivity. The IC-M504’s superior receiver provides excellent resistance to intermodulation and allows you to catch a weak signal between strong stations. Excellent audio output power 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. 25W hailer/RX speaker and auto foghorn 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 foghor
