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.

IC-M73PLUS Features

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.

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.
