GMDSS fixed VHF GM600

The Icom GM600 VHF is a fixed marine communication station designed to meet the strict requirements of the Global Maritime Distress and Safety System (GMDSS). It enables clear voice communications and integrates Digital Selective Calling (DSC) for emergency and routine situations.

Yes, the GM600 VHF holds the MED (Marine Equipment Directive) certification, as well as SOLAS, ITU-R M.493-13 DSC, and IMO A.694(17) certifications. It is therefore fully approved for use on commercial and professional vessels.

The GM600 VHF offers two transmit power levels: a maximum of 25 W for long-range communications, and a reduced 1 W setting for short-range exchanges, allowing you to save power and minimize interference.

Yes, the front panel of the GM600 VHF radio has an IPX7 waterproof rating. This means it is waterproof and can withstand immersion in water at a depth of 1 meter for 30 minutes.

The main unit dimensions (excluding projections) are 274 mm width, 114 mm height, and 121.5 mm depth. It is important to allow sufficient space at the rear for cable routing during installation.

The fixed VHF GM600 weighs approximately 1.6 kg, making it a robust unit suited for demanding marine environments.

The GM600 VHF complies with IEC 61162-1 (NMEA 0183 compatible). It accepts RMC, GGA, GNS, GLL, and VTG sentences as input to retrieve position data. It outputs DSC and DSE data to other devices.

Yes, the GM600 VHF is equipped with a Centronics IEEE1284 port. This allows connection of a compatible printer to directly print received ASN (DSC) messages, a common requirement on commercial vessels.

Yes, you can connect an external speaker. The VHF delivers an impressive 10 W audio power under a 4 Ω load for the external speaker, ensuring excellent audibility even in noisy environments.

The GM600 VHF's internal speaker delivers an audio output power of 2 W, which is typically sufficient for clear listening in the helm or pilot house.

The GMDSS fixed VHF GM600 is supplied with the HM-214V hand microphone.

The GM600 transmits (Tx) on the frequency range 156.025 to 161.600 MHz and receives (Rx) from 156.025 to 162.000 MHz. It also features a dedicated receiver for continuous monitoring of channel 70 (156.525 MHz).

Although it is designed and certified for professional vessels subject to SOLAS/GMDSS regulations, the GM600 VHF is fully compatible with recreational boats or offshore yachts seeking a very high-reliability communication device.

Connection to the GPS is made via the IEC 61162-1 communication ports located at the rear of the device. Simply connect the NMEA 0183 output wires from your GPS to the corresponding inputs on the VHF to provide it with your exact position.

When transmitting at maximum power (25 W), the GM600 VHF consumes approximately 3.3 A. In receive mode, with the audio volume at maximum, consumption is approximately 2.0 A.

Yes, in compliance with GMDSS standards, the GM600 VHF integrates a dedicated Class A ASN (Digital Selective Calling) receiver. It continuously monitors channel 70 (156.525 MHz), even when you are using another channel for communication.

The HM-214V handheld microphone supplied with the GM600 VHF is designed to withstand harsh marine environments. It matches the ruggedness of the radio’s waterproof front panel (IPX7).

You need a standard marine VHF antenna (50 Ω impedance) of good quality. To ensure GMDSS performance, it is crucial that the antenna is installed as high as possible and clear of any obstructions.

Yes, the VHF GM600 is designed to be flush-mounted in a console or dashboard. Ensure you respect the cut-out dimensions and allow adequate ventilation at the rear of the unit to dissipate heat.
