IC-M73
IC-M73PLUS

Slim, Stylish, Powerful VHF with Professional Features

Open

IPX8 Submersible Plus™

The IC-M73 maintains our highest level of waterproof protection, delivering unparalleled durability. This radio has undergone rigorous testing and has proven its ability to survive being submerged in water up to a depth of 1.5 meters (4.9 feet) for 30 minutes.

Slim, Hourglass Body Wide Viewing Angle LCD

The IC-M73 features a sleek and ergonomic design that combines style with functionality. Its durable and rugged body ensures user-friendly operation and a long lifespan. The high-intensity LCD with a wide viewing angle provides bright and easily readable characters, enhancing the overall user experience.

700 mW Loud Audio

The IC-M73 utilizes a BTL (bridge-tied load) amplifier, effectively doubling the audio output for enhanced performance. Its internal speaker produces a powerful 700mW audio output, ensuring clear and loud sound quality.

AquaQuake™ Water Draining Function

The AquaQuake™ prevents audio degradation from a water-logged speaker. This function removes water from the speaker grill by vibrating the speaker cone. You can hear clear audio with this function.

6 W RF Output Power

The IC-M73's 6 Watts of transmit power provides extended communication range for the user. A large capacity Lithium-Ion battery, BP-245H allows for 17 hours of operation, under normal conditions*.

* Typical operation with 5:5:90 duty ratio. 20 hours for basic version.

Dualwatch and Tri-watch function

The Dualwatch and Tri-watch functions allow for periodic checking of Channel 16 while operating on another channel. This feature proves convenient when communicating with your friends' vessels or during sailing regattas, enabling you to make important announcements about the race.

Last Call Voice Recording*

The last call voice recording function automatically saves the last incoming call for 1 minute. You can also start recording manually. You will not miss an important call.

* Available in the IC-M73 PLUS only

Active Noise Cancelling Technology*

The built-in bidirectional active noise cancelling reduces background noise to up to 90% and improves both your transmitted voice and incoming call. You will hear better and clearer!

* Available in the IC-M73 PLUS only

Bass Boost Function*

The signal processing technology emphasizes low-pitched sound to provide a rich bass sound for both transmit and receive signals.

* Available in the IC-M73 PLUS only
