Marine VHF, DSC and AIS service in the Upper Florida Keys
Radio problems are a system problem until proven otherwise. Power, coax, antenna, GPS position, MMSI/DSC configuration, AIS data, and installation quality all matter.

Problem first
Symptoms worth testing instead of guessing
A radio that powers on is not necessarily transmitting, receiving, identifying, or sharing position correctly.
- Short or inconsistent transmit and receive range
- DSC position or identity data is missing or incorrect
- AIS targets disappear, own-vessel data is wrong, or alarms persist
- Noise, weak audio, voltage drop, or intermittent resets occur
- Coax, antenna, GPS, or network connections have unknown condition
Method
Scope it. Test it. Prove it.
The point is a useful diagnosis and a defined next step—not parts roulette.
Test
Check power and voltage behavior, coax and connectors, antenna path, GPS/DSC data, AIS integration, and configuration.
Verify
Correct the scoped issue and confirm the system's operating behavior and data path before closeout.
Before scheduling
Useful information before the visit
Send enough detail to tell whether the problem fits Zenith's scope and what the first visit should accomplish.
Scope note: Non-GMDSS compulsory ship-radio inspection inquiries are screened separately for vessel applicability, equipment scope, calibrated-test requirements, and independence before scheduling. No statutory sign-off is implied by a general service request.

Straight answers
Common questions
Can you troubleshoot poor VHF range?
Yes. Power, voltage drop, coax, connectors, antenna path, installation condition, and radio behavior are checked as a system.
Can you configure DSC and AIS data sharing?
Yes, when the connected equipment supports the required GPS, identity, network, and configuration functions.
Do you perform FCC ship-radio inspections?
Potential non-GMDSS inspection work is screened before scheduling for vessel applicability, scope, calibrated equipment, and independence requirements.
