Frequently Asked Questions (FAQs)

1. What is an MF/HF radio used for?
MF/HF radios enable long-range voice and data communication for ships operating beyond VHF range, including GMDSS distress alerts.

2. Is MF/HF mandatory on all vessels?
Yes, for SOLAS-compliant vessels on international voyages outside VHF coverage, MF/HF GMDSS equipment is mandatory.

3. What does DSC mean on MF/HF?
Digital Selective Calling (DSC) allows automatic distress signals and selective ship-to-ship or ship-to-shore calling with MMSI ID.

4. How often should MF/HF be tested?
Routine functional checks are recommended monthly, with annual GMDSS testing required by class authorities.

5. Can you repair HF antenna issues?
Yes. We provide tuning, grounding inspection, SWR testing, and coupler replacement for faulty antenna systems.

6. Which brands do you service?
We support Sailor (Thrane), JRC, Furuno, Icom, Samyung, and other major IMO-compliant MF/HF radios.

7. Can you program MMSI numbers?
Yes. Our engineers can program, reconfigure, or reset MMSI and SELCALL details during service.

8. Is NBDP still required?
Yes, Narrowband Direct Printing (NBDP) is still a GMDSS requirement for Sea Area A3 communications via HF Telex.

9. What causes HF radio transmission loss?
Common issues include antenna disconnection, grounding faults, power supply failure, or damaged couplers.

10. How do I schedule an MF/HF inspection?
You can email service@ftron.net to arrange onboard inspection, class survey, or emergency repairs.
