GMDSS GOC HF Distress Frequency Flashcards
24 English flashcards for GMDSS GOC revision. Match the five HF distress DSC and voice pairs and catch mistakes in paper readouts.
Tentang dek ini
Practise the five HF distress frequency pairs used in GMDSS, the Global Maritime Distress and Safety System. Each pair links a digital selective calling (DSC) frequency to a radiotelephony (voice) frequency in the same band. The deck is for trainees revising for the General Operator’s Certificate (GOC) on paper or with simulated readouts.
Start by recalling both frequencies for HF4, HF6, HF8, HF12 and HF16. Then match DSC to voice and voice to DSC. The final cards ask you to read a band label, spot a mix-up between bands or modes, or check a decimal or unit. Related questions are spaced through the deck. Other bands, band selection and radio procedures are outside the scope of these frequency-matching exercises.
The frequency pairs were checked against the IMO distress frequency table and ITU Radio Regulations, Appendix 15. The questions were written independently with AI assistance, and the cover is an original AI-generated illustration. No examination questions, mark schemes or curriculum text were copied. CC0 applies to original material and generated media to the extent applicable rights exist.

Pertanyaan
A paper HF8 distress row shows DSC 8291 kHz and voice 8414.5 kHz. What is the error?
Jawaban
The labels are swapped. DSC is 8414.5 kHz and voice is 8291 kHz.
Kartu 17
Pertanyaan
A paper HF4 distress row shows 4207.5 kHz in both columns. Which column is wrong, and what belongs there?
Jawaban
The voice column should show 4125 kHz. The DSC entry is correct.
Kartu 18
Pertanyaan

Jawaban
Yes. DSC is 12577 kHz and voice is 12290 kHz. The trailing zeros leave the frequencies unchanged.
Kartu 19
Pertanyaan

Jawaban
6312 kHz. One MHz equals 1000 kHz.
Kartu 20
Pertanyaan
A paper HF16 distress row shows DSC 16804.0 kHz and voice 16420 kHz. Which entry needs a correction?
Jawaban
The DSC entry should be 16804.5 kHz. The voice entry is correct.
Kartu 21
Pertanyaan
