VHF Marine Handheld Transceiver | 156-163MHz, 6 Watt, Submersible

Product Description

The M73’s ergonomic design fits easily in the user’s hand and is a rugged, durable radio. The large screen and high-intensity LCD offer bright and easy-to-read characters. Yacht customers benefit from the optional VOX headset and adapter option that allows someone handling dock lines to use both hands while docking the boat, simultaneously communicating with the captain. The last call voice recording function automatically saves the last incoming call for 1 minute. You can also start recording manually. The built-in bidirectional active noise cancelling reduces background noise to up to 90% and improves both your transmitted voice and incoming call. The signal processing technology emphasizes low-pitched sound to provide a rich bass sound for both transmit and receive signals. 

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. 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. 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. 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.
