Scenario briefing
Key teaching points
- Open on Channel 16: "[station name × 3], THIS IS [your vessel × 3], OVER".
- Once acknowledged, request a working channel: "Switch to channel [X], OVER".
- Conduct the conversation on the working channel; return to Channel 16 watch on completion.
- A radio check on Channel 16 is acceptable for testing the radio — but say "RADIO CHECK" so other stations know not to respond.
Common mistakes to avoid
- Conducting the entire conversation on Channel 16 — it ties up the calling/distress channel.
- Skipping the initial three-times station identification — receivers need it to confirm the call is for them.
Why it matters
Routine VHF calls are 95% of the radio traffic a recreational skipper ever makes — calling a marina, requesting a radio check, contacting a lifeboat for advice. The correct format on Channel 16 followed by a switch to a working channel is the rule the SRC exam tests most often.
Exam relevance
Routine call procedure is the most-tested format in the VHF SRC oral; STCW GOC candidates must demonstrate the Channel-16-to-working-channel transition.
