Icom IC-M73

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

IPX8 Submersible Plus™
The IC-M73 continues to offer Icom’s best waterproof protection. The radio has been tested to survive after being submersed in 1.5m (4.9ft) depth of water for 30 minutes.

700mW 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.

6W 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 allows for 16 hours of operation, under normal conditions*. * Typical operation with 5:5:90 duty ratio. 18 hours for basic version.
