Scenario briefing

Key teaching points

Incoming DSC routine call triggers an audible alarm and an on-screen prompt.
Acknowledge via the menu — ACCEPT or ACK — which sends an automated reply on Channel 70.
Switch to the proposed working channel for voice contact.
Call once on the working channel — DSC has already established initial contact.

Common mistakes to avoid

Ignoring the alarm and switching off — DSC alerts have legal weight.
Replying on Channel 70 by voice — forbidden, voice goes on the agreed working channel.

Why it matters

Receiving an incoming DSC call is half the digital protocol and the half most candidates fluff because the menu navigation differs from outgoing calls. Acknowledging correctly and switching to voice is the SRC exam probe.

Exam relevance

Receiving and ACKing a DSC routine call is examined in the VHF SRC oral; candidates must navigate the menu without prompting.
