VHF Communication System
VHF Radios • All volunteers with the CCGA are expected to have their Radio Operator’s Certificate.
VHF Radios Off/ On/ Volume Transmit DSC Frequency Selector Mode High/Low Power Squelch
VHF Radios • Squelch - adjust the receiver sensitivity and limits unwanted radio noise. Too high a squelch will result in weaker signals not being heard. • Channel/ Mode - Keep the radio in USA/CDA mode at all times. • Simplex channels transmit and receive on same frequency - duplex send and receive on different frequencies.
VHF Radios • Hi/Lo - this control the power with which the VHF will transmit. High is generally 25 W whilst Low is about 5 W. • Handheld VHFs have a high of about 5 W and a low of about 1 W.
VHF Radio Procedures • Use Channel 16 for calling only, except for MAYDAY. Monitor at all times. • Name the station being called x 2, followed by the calling stations name or call sign x 2. • Always identify yourself when calling. • Use standard marine language and vocabulary

Communications
Communications • • B A S S Brevity Accuracy Speed Secrecy
Communications 1 • Think before you speak • Key the microphone for 1 second before speaking • Keep messages short and to the point • Use a working channel - not Channel 16 • Check the channel is clear before speaking • Keep microphone about 2 inches from the mouth
Communications 2 • • Talk in a calm and clear voice Do not use offensive language Preface all distress calls with distress signal Use proper words and expressions Spell names phonetically Say numbers individually Do not “on air” for prolonged periods
Distress Communications
Distress Communications • The Global Maritime Distress and Safety System applies to all vessels of 300 gross registered tons, or carrying passengers on international voyages
Distress Communications • Sea Area A 1 Within range of shore-based VHF DSC coast station (40 nautical miles) • Sea Area A 2 Within range of shore-based MF DSC coast station (excluding sea areas A 1)(150 nautical miles)
Distress Communications • Sea Area A 3 Within the coverage of an Inmarsat geostationary satellite (approximately 70°N to 70°S) (excluding sea areas A 1 & A 2) • Sea Area A 4 The remaining areas outside sea areas A 1, A 2 & A 3 (polar regions)
Distress Communications
Distress Communications
Digital Selective Calling • Channel 70 on VHF is dedicated to DSC. • Each DSC has a unique 9 digit number called a “Maritime Mobile Service Identifier”. • Canadian vessels start with “ 316”
EPIRBs, ELTs and SARTs
EPIRBs, ELTs and SARTs • All Emergency Position Indicating Radio Beacons (Marine), Emergency Location Transmitters (Aircraft), and Search and Rescue Transmitters transmit on either 121. 5 or 406 MHz • EPIRBs all have their own unique identification number.
EPIRBs • Emergency Position Indicating Radio Beacons • Automatic EPIRBs will float free and be activated by water • Manual activation will require removal from their brackets and activated.
ELTs • Emergency Locator Transmitters are fitted to aircraft and also transmit on 406 MHz
Search And Rescue Transponder • SARTs
Distress Messages
Distress Messages • Procedure for Channel 16: 1. Transmit an alarm signal. 2. Say “MAYDAY, MAYDAY”. 3. “This is RCM-SAR 13, RCMSAR 13”. 4. Give vessel position be latitude/ longitude of bearing and distance from identifiable point. 5. State the nature of distress and assistance required.
Distress Messages 6. State number of persons on board, injuries and other vessels involved. 7. Describe your vessel. 8. Provide any other pertinent information to assist rescuers. 9. REPEAT, say “Over” and listen
Distress Messages • Imposition of Silence “SEELONCE MAYDAY” • Finish of Mayday “MAYDAY FINIS” • Urgency “PAN, PAN” x 3
Distress Messages • If you are underway and you hear a distress message and no-one else answers, answer the vessel, gather and log all information given, and pass information to Joint Rescue Coordination Centre or Marine Communications and Traffic Services.
