FAQ

 

 

01. What is its effective communication range, and how do I fix weak signal reception?

Under standard sea-level conditions, the transceiver delivers a reliable communication range of 20 to 30 nautical miles, varying slightly with antenna height and sea state. For weak or unstable signals, start with antenna inspection: mount the antenna at a high, unobstructed mast position, free from blockages by superstructures or cargo, and replace corroded or aging coaxial cables. Avoid operating the radio near high-power radar and electrical equipment that causes electromagnetic interference. In fog or rough seas, activate the device's dedicated long-distance receiving mode to filter ambient noise and stabilize signal quality.

02.Does it support group calls, area calls and distress relay functions?

Yes. As a full-spec professional Class A device, it supports all advanced DSC call types exclusive to commercial-grade radios. This includes individual vessel calls, custom fleet group calls, designated geographic area calls, distress acknowledgements, and full distress relay functionality. These features are vital for commercial fleet coordination, offshore operation scheduling, and maritime emergency response. During crises, the radio can relay incoming distress signals to surrounding vessels and coastal stations, expanding rescue coverage and improving overall maritime safety efficiency.

03.How to resolve unclear audio or static noise during communication?

Most audio noise and muffled sound issues stem from external interference or minor setup problems, not hardware failure. First, confirm you are using the correct international VHF channel to avoid frequency overlap with nearby vessels. Second, clean blocked salt residue and water stains from the handset microphone vent, a common cause of dull audio. Third, enable the built-in noise reduction and audio filtering to suppress wind and wave background noise while underway. If static persists, inspect antenna connections-loose or damaged antenna leads are the main cause of transmit and receive static interference.
