The Icom IC-M423GE is a compact fixed VHF marine transceiver designed for modern boating needs. It integrates advanced features such as a built-in GNSS GPS receiver, active noise cancelling technology, and a high-contrast white backlit LCD display. The device is engineered for durability with IPX7 waterproof protection, ensuring reliable performance in various marine environments.
- Built-in GNSS GPS Receiver: Equipped with a high-performance GNSS receiver supporting GPS, GLONASS, and SBAS, the IC-M423GE provides accurate positioning data. An external GPS antenna is included to enhance signal reception.
- Active Noise Cancelling: Utilizes digital processing to reduce background noise by up to 90% in received signals and 30% in transmitted signals, ensuring clear communication in noisy environments.
- High-Contrast White Backlit LCD and Keypad: Features a white backlit LCD screen and laser-cut keys for intuitive operation and enhanced visibility, complementing modern boat designs.
- 10 W Loud Audio, Public Address, and Foghorn: Includes a built-in 10 W amplifier for loud audio output through external speakers, a public address function for announcements, and a foghorn feature for signaling.
- Built-in Class D DSC (Digital Selective Calling): Monitors Channel 70 for DSC activity, even while receiving on another channel, and supports distress, individual, group, all ships, urgency, safety, position request/report, polling request, and DSC test calls.
- AquaQuake™ Function: Employs infrasound to eject water from the speaker, ensuring clear audio output after exposure to water.
- Dual/Triple Watch Function: Allows monitoring of Channel 16 and/or a call channel simultaneously, enhancing situational awareness.
- NMEA 0183 Connectivity: Enables integration with compatible marine electronics for comprehensive navigation and communication systems.
- Optional Remote Control Microphone (COMMANDMIC™ HM-195GB/GW): Provides full control of the IC-M423GE from a separate cabin or tower, with intercom functionality between the microphone and transceiver.
