Course length

10 hours + exam

The current RYA course specification sets ten hours of learning and states that exam time is additional.

Training

Classroom or online

Either route covers the same SRC knowledge; the examination is completed in person at an RYA Recognised Training Centre.

Experience

None required

The current RYA course finder lists no required previous experience.

Exam age

16 minimum

A candidate must be at least 16 on the examination date; the current application form does not impose the same age limit on course attendance.

Assessment

Written + practical

The official examination combines a written theory question paper with a practical marine VHF assessment.

Radio scope

VHF + VHF DSC

SRC covers marine VHF radiotelephony and Digital Selective Calling on channel 70 within its qualifying-vessel scope.

GMDSS focus

Sea Area A1

The syllabus places VHF and DSC in the coastal GMDSS structure while explaining the wider system and its equipment.

Channel 70

DSC only

Channel 70 is reserved for digital signalling; associated voice traffic moves to the appropriate voice channel.

Two permissions

Operator + station

The personal operator certificate does not replace the relevant Ofcom Ship Radio or Ship Portable Radio Licence for the equipment.

Public exam data

No fixed figures

Current public RYA learner material does not state one universal written question count, written duration, pass mark or practical duration.

How to prepare for the Marine Radio SRC

Prepare in the same order a safe radio operation unfolds.

1

1. Confirm authority and identities

Separate the operator certificate from the station licence, then identify the vessel call sign, MMSI and the limits of SRC authority.

2

2. Learn the radio controls

Set power, channel, volume and squelch deliberately and understand antenna, range, simplex, duplex and channels 16 and 70.

3

3. Build disciplined routine calls

Use the correct identity, calling channel, working channel, phonetic spelling, prowords, position and concise message order.

4

4. Pair DSC with voice

Select priority, address and proposed channel, transmit the digital alert, then move to the correct voice follow-up.

5

5. Rehearse emergency operation

Practise distress, urgency, safety, received-alert and false-alert sequences on training equipment before the written and practical assessment.

How to use this guide

How to prepare for the Marine Radio SRC

Build from station licensing and radio controls to disciplined voice and DSC traffic, then rehearse distress, urgency, safety, false-alert and GMDSS decisions on training equipment.

1. Prepare

Confirm authority, station identity, position, equipment condition, listening watch and the facts that must be communicated.

2. Select

Choose the correct priority, addressee, DSC category, working channel and power for the situation.

3. Send

Transmit the intended DSC alert or voice call only after checking identity, position, priority and channel.

4. Speak

Give the required voice call and message clearly, briefly and in the correct operational order.

5. Monitor and correct

Listen for acknowledgement and instructions, protect priority traffic, update information and cancel accidental alerts by the correct procedure.

Certificate, Law and Station Licensing
Written theory

SRC Authority, Scope and Higher Certificates

What the SRC authorises, its VHF/DSC and GMDSS Sea Area A1 focus, and when MF/HF, mandatory-fit or STCW operations require a different certificate.

Key rules

Rule 1

The SRC is the minimum operator qualification for marine VHF and VHF DSC on a qualifying UK-flagged vessel voluntarily fitted with radio equipment.

Exam cue: Identify the radio band, voyage area, vessel type and whether the radio fit is voluntary or mandatory.

Rule 2

The certificate covers international maritime VHF frequencies, including channel 70 for DSC, and supports non-SOLAS operation in GMDSS Sea Area A1.

Exam cue: Separate VHF operator authority from ownership, vessel qualification and equipment licensing.

Rule 3

MF/HF or satellite operation on a voluntarily fitted pleasure vessel requires the LRC, while mandatory-fit and STCW roles may require ROC or GOC rather than SRC.

Exam cue: Choose the higher certificate before using equipment outside SRC scope.

Common traps

Treating SRC as authority to operate MF, HF or every satellite terminal.

Prevention: Do not present the 601-item authoring target as an official RYA paper and do not treat static study as a substitute for the recognised written and practical examination.

Assuming an SRC is an STCW radio qualification for a mandatory-fit ship.

Prevention: Do not present the 601-item authoring target as an official RYA paper and do not treat static study as a substitute for the recognised written and practical examination.

Using vessel tonnage alone without checking the statutory radio-fit and role.

Prevention: Do not present the 601-item authoring target as an official RYA paper and do not treat static study as a substitute for the recognised written and practical examination.

Memory anchors

SRC

Short Range Certificate for marine VHF and VHF DSC in the non-SOLAS Sea Area A1 context.

FAQ

Common RYA Marine Radio SRC questions

Is this an official RYA course, exam or question bank?

No. This is an independent non-question study-guide module aligned to current public RYA, MCA and Ofcom material. Only an RYA recognised training and assessment route can provide the recognised course and SRC examination.

What does the SRC authorise?

Within its stated vessel scope, the SRC is the operator qualification for marine VHF voice and VHF DSC, including channel 70. It does not itself license the transmitting equipment and does not extend to MF or HF.

Do I need both an operator certificate and a radio licence?

Yes where the equipment is installed or carried for ordinary use. The SRC concerns the operator. Ofcom's Ship Radio or Ship Portable Radio Licence covers the station or portable equipment and supplies or records identities such as the call sign and MMSI.

Can I complete the whole qualification online?

No. The learning may be completed online, but the written and practical examination takes place in person at an RYA Recognised Training Centre. Online candidates should arrange the exam and allow time to become familiar with the centre's training radios.

What is the current exam structure?

RYA publishes two components: a written theory question paper and a practical assessment using marine VHF equipment. The practical and written work cover voice procedures, Class D DSC operation and the governing rules, with particular emphasis on distress and urgency.

How many written questions are there, how long is the exam and what is the pass mark?

Current public RYA learner pages and the current application form do not publish one universal question count, written-paper duration, practical duration or pass percentage. Use the recognised centre's current joining instructions rather than treating provider mocks or legacy figures as official.

Does sending a DSC alert replace the voice message?

No. DSC alerts and establishes the digital priority and identity information. The operator then follows on the appropriate voice channel with the required radiotelephony call and message, including a Mayday voice call and message after a distress alert.

When should Mayday, Pan-Pan and a safety call be used?

Mayday is for grave and imminent danger requiring immediate assistance. Pan-Pan is for an urgent message concerning safety without meeting the distress threshold. Safety priority introduces an important navigational or meteorological warning. The situation, not convenience, determines the priority.

What does GMDSS Sea Area A1 mean for SRC study?

A1 is the area within radiotelephone coverage of at least one VHF coast station maintaining continuous DSC alerting. SRC study centres on VHF and DSC operation there while introducing NAVTEX, EPIRBs, SARTs, satellites and the wider A1-A4 structure.

When is a different operator certificate needed?

MF, HF or relevant satellite operation on a voluntarily fitted pleasure vessel calls for the Long Range Certificate. Vessels legally required to carry GMDSS equipment and STCW radio roles may require the Restricted Operator's Certificate or General Operator's Certificate instead of SRC.

Can someone without an SRC use the radio in a life-threatening emergency?

Ofcom's licence terms permit anyone to use the equipment to summon assistance when there is a risk to life. That emergency provision does not remove the normal requirements for licensing, competent control and correct routine operation.

Can this guide replace hands-on radio practice?

No. Static study can explain sequence and judgement, but the official exam also tests practical control of marine VHF and Class D DSC training equipment. Practise setup, channel and power selection, DSC menus, push-to-talk discipline, voice calls and false-alert recovery on suitable training radios.
