VHF Radios
  • All volunteers with the CCGA are expected to have
    their Radio Operators Certificate.

High/Low Power
Squelch

22
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.

23
VHF Radios
  • Hi/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.

24
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 x2.
  • Always identify yourself when calling.
  • Use standard marine language and vocabulary

25
VHF Marine Language
  • Over Out Roger
    Wilco
  • Channel Say again I say again Standby
  • All after Word after All before Word
    before
  • Affirmative Negative That is correct
  • Correction Read back I spell Break
  • Seelonce Seelonce finis

26
Phonetic Alphabet
Because it is easy to confuse the sounds of some
letters, when spoken over a radio, their phonetic
equivalent is used instead.. Alfa Bravo Charlie
Delta Echo Foxtrot Golf Hotel India
Juliett Kilo Lima Mike November Oscar Papa
Quebec Romeo Sierra Tango Uniform Victor Whiske

    tons, or carrying passengers on international
    voyages

35
Distress 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)

36
Distress Communications
  • Sea Area A3 Within the coverage of an Inmarsat
    geostationary satellite (approximately 70N to
    70S) (excluding sea areas A1 A2)
  • Sea Area A4 The remaining areas outside sea areas
    A1, A2 A3 (polar regions)

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

40
EPIRBs, ELTs and SARTs
41
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 406MHz
  • EPIRBs all have their own unique identification
    number.

42
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.

43
ELTs
  • Emergency Locator Transmitters are fitted to
    aircraft and also transmit on 406 MHz

44
Search And Rescue Transponder
  • SARTs

45
Distress Messages
46
Distress 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. Give vessel position be latitude/ longitude of
    bearing and distance from identifiable point.
  • 5. State the nature of distress and assistance
    required.

47
