Fixed Mount VHF and AIS Receiver C with NMEA 2000™ Connectivity


Integrated AIS Receiver*

With an integrated AIS receiver, the IC-M506 can show real-time AIS vessel traffic information on the display. The AIS target call function allows you to easily set up a DSC individual call. The Plotter, Target list, and Danger list can be toggled on the display.

* AIS receiver and NMEA 2000 interface units are A IS options, depending on version.


Last Call Voice Recording

The last call voice recording function automatically saves the last two minutes of the last incoming call. You can replay the received call, and not miss any incoming call.


Active Noise Cancelling

Using digital signal processing technology, the built-in bidirectional active noise canceling provides superb performance. It reduces background noise to up to 90% in the received signal and 30% fixed in the transmitting signal. The function OFF setting is also possible.


Intuitive Menu-Driven User Interface

The intuitive software key functions provide an easy and fast operation to control the multiple functions of the IC-M506. The bottom line of the dot-matrix display shows the software key functions which can be toggled with the left and right buttons.

When connected to an external hailer horn, you can talk to people on the deck or shore from the radio’s microphone and can hear people’s reply via the hailer speaker. The RX hailer function allows you to monitor the received audio from the hailer horn. The built-in 25W amplifier increases your talk power, making it loud and clear.
