22VHF RadiosSquelch - 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.
23VHF RadiosHi/Lo - this control the power with which the VHF will transmit. High is generally 25W whilst Low is about 5W.Handheld VHFs have a high of about 5W and a low of about 1W.
24VHF Radio ProceduresUse 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 x2.Always identify yourself when calling.Use standard marine language and vocabulary

35Distress Communications Sea Area A1 Within range of shore-based VHF DSC coast station (40 nautical miles)Sea Area A2 Within range of shore-based MF DSC coast station (excluding sea areas A1)(150 nautical miles)
36Distress Communications Sea Area A3 Within the coverage of an Inmarsat geostationary satellite (approximately 70°N to 70°S) (excluding sea areas A1 & A2)Sea Area A4 The remaining areas outside sea areas A1, A2 & A3 (polar regions)
41EPIRBs, ELTs and SARTsAll Emergency Position Indicating Radio Beacons (Marine), Emergency Location Transmitters (Aircraft), and Search and Rescue Transmitters transmit on either or 406MHzEPIRBs all have their own unique identification number.
42EPIRBs Emergency Position Indicating Radio Beacons Automatic EPIRBs will float free and be activated by waterManual activation will require removal from their brackets and activated.
43ELTsEmergency Locator Transmitters are fitted to aircraft and also transmit on 406 MHz
46Distress Messages Procedure for Channel 16: 1. Transmit an alarm signal.2. Say “MAYDAY, MAYDAY, MAYDAY”.3. “This is RCM-SAR 13, RCM-SAR 13, RCM-SAR 13”.4.
