Icom’s M506 line of fixed-mount radios includes five models that come equipped with a number of different functions, including a fully integrated AIS receiver, NMEA 2000 connectivity and a rear-mounted mic connector. All M506 radios also have “last call” capability, which automatically saves the last two minutes of an incoming call, so you won’t have to worry about missing a transmission again, and can support a remote mic. The system is robustly built to the IPX8 submersible waterproofing standard. An intuitive soft-key interface complements the radio’s large 132-by-96-pixel dot-matrix display. From $449.
