ICOM IC M604
CALL FOR PRICE
Superior receiver performance
The IC-M604 has excellent receive specifications* which allow a weak signal a better chance of being heard when louder signals are around it. The powerful 5.0W (typical) audio output from the front facing speaker further increases the audibility and quality of received calls.
* More than 80dB for intermodulation rejection and adjacent channel selectivity, and 0.22μV (typical) high sensitivity.
Large LCD with dot-matrix characters
The large full dot-matrix display is designed for optimum readability in any lighting condition. With the extra large font, the channel number is maximized on the display and upper and lower case characters can be easily read.
30 Watt 2-way hailer capability
When connected to an external hailer horn, communication with other boats, deck or dock hands is easy. The built-in 30W amplifier increases your talk power making your message loud and clear. Four foghorn patterns are also available.
(1m depth for 30 minutes)
The IC-M604, including the supplied microphone, withstands submersion in up to 1.0m depth of water for 30 minutes. It is equivalent to IPX7 waterproofing.*
* except cables
Built-in ITU Class-D DSC
No matter what channel you're tuned to, a separate and independent receiver inside the M604 continuously monitors Ch. 70. The 10-keypad allows simple and efficient operation of the DSC emergency functions, vital for your safety at sea.
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 GPS or navigation equipment*. In addition, the polling (request/ reply) function checks whether a specific ship is within the communications range.
* NMEA 0183 format is required.
Improved GPS information indication
When connecting to an external GPS receiver, the GPS information indication function shows course and speed data as well as position, date and time on the display.
Front and rear panel microphone connection

RX speaker function
The RX speaker function, receiver-repeater allows you to monitor the received radio audio from a hailer horn on the deck or tower. You can also make an announcement on-board from the microphone.
