VHF MARINE TRANSCEIVER

IC-M73

Slim, Stylish, Powerful VHF with Professional Features

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.

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!

Bass Boost Function

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

700 mW Loud Audio

The IC-M73 uses a BTL (bridge-tied load) amplifier that doubles the audio output. Its internal speaker delivers a loud 700mW audio output with clear sound.

6 W RF Output Power

The IC-M73's 6 Watts of transmit power will provide 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.

IPX8 Submersible Plus™ Waterproofing

The IC-M73 continues to offer Icom's best waterproof protection. The radio has been tested to survive after being submersed in 1.5 m (4.9 ft) depth of water for 30 minutes.

Slim, Hourglass Body Wide Viewing Angle LCD

The IC-M73 has a stylish, ergonomic design. A durable and rugged body provides user-friendly operation and long life. A wide viewing angle, high intensity LCD offers bright, easy to read characters.
