VHF / DSC service
Power, audio, controls, programmed identity, GPS position input and digital selective calling functions checked as one radio system.
← All three specialties
Specialty 03 · Marine radio + FCC
The call has to leave the boat.
Zenith treats VHF, DSC and AIS as complete systems—from protected power and programmed identity to GPS input, coax, antenna and radio-frequency performance.

Radio scope
From supply voltage to antenna.
AIS + RF path
AIS equipment, coax, connectors, antenna installation and radio-frequency path assessed together instead of blaming the radio first.
FCC ship-radio inspections
Compulsory non-GMDSS ship-radio inspections and applicable certification for covered vessels under the relevant Part 80 scope.
What gets checked
A bright display does not prove the radio works.
- Supply voltage, branch protection and grounding
- MMSI, GPS position input and DSC behavior
- Coax condition, connectors and antenna installation
- Transmit and receive performance through the RF path
- Required equipment, operation and records for covered vessels
