Hello and welcome back....Marine radio can be broken into 3 parts = 27mhz, Marine VHF & HF band.
27mhz band also known as Marine CB Band
27 MHz is the main frequency used by recreational boaters and the volunteer services because of its low cost and its suitability for use in enclosed waters where the majority of recreational boaters operate. This radio provides a range of 10 -15 nautical miles which is usually limited to line of sight.
27 MHz radios allow ship-to-ship and ship-to-shore communication with the volunteer services. 27MHz radios are capable of transmitting distress alerts, receiving weather forecasts and marine safety information provided that the vessel is operating within the coverage area and times of the volunteer services.
The National Volunteer Marine Rescue Committee has decided to discontinue the monitoring of distress, urgency and safety channels on the 27 MHz band from 2015.
FREQUENCIES
ch 72 = 27.720 ship-ship, ship-shore
ch 82 = 27.820 ship-ship, ship-shore
ch 86 = 27.860 ship-ship, ship-shore
ch 88 = 27.880 distress, safety & calling
ch 90 = 27.900 non-commercial service
ch 91 = 27.910 non-commercial service
ch 94 = 27.940 non commercial service, club events & services
ch 96 = 27.960 non-commercial service
ch 98 = 27.980 surf life saving, volunteer coastal patrol, various rescue groups
MARINE VHF BAND
VHF radios have a better range and clarity than 27 Mhz radios but are slightly more expensive. The Uniform Shipping Laws (USL) Code states that effective VHF coverage only extends to 20 nautical miles from a shore station but may be as far as 30 nautical miles under some circumstances, such as where repeaters are used.
VHF also allows ship-to-ship and ship-to-shore communications with the volunteer services and the three port corporations. This radio is therefore capable of transmitting distress signals, receiving weather forecasts and marine safety information.
Modern VHF radios have the additional feature of Digital Selective Calling (DSC) that allows distress alerting at the push of a button. Urgency and routine alerts, (such as position reporting) are also available to DSC users. To utilise the full range of features in a VHF DSC radio it must be interfaced with Global Positioning Service (GPS) equipment and programmed with a Maritime Mobile Service Identity (MMSI).
Users of VHF radio must hold (or be supervised by a holder of) a minimum of a Marine Radio Operators VHF Certificate of Proficiency. For details how to obtain this qualification, contact your local Marine Rescue NSW Unit.
Due to the discontinuing of distress, safety and urgency monitoring of 27 MHz by volunteer marine rescue agencies Australia-wide, boaters are encouraged to purchase VHF radio equipment and ensure they are appropriately certified for its use.
VHF Channels and their use:
Channel 16 – for distress and calling. Always change to another channel after calling
Channel 67 – supplementary distress and calling channel. Also used for safety broadcasts.
Channel 73 – mostly used for vessels talking to a Marine Rescue NSW shore station
Channel 72 and 77 – for ship-to-ship working. Use this to pass messages between vessels.
Channel 21, 22, 80, 81 & 82 – repeaters. Used for passing information about vessel movements and the safety of vessels and persons. Keep messages as brief as possible (no more than one minute in total) and DO NOT use these channels for chatter. Not all channels are available in a given area. Ask your local Marine Rescue NSW Unit for more information.

HF MARINE
HF is used for long distance ship to shore communication at a cost of around $4,000. HF coverage is highly variable and dependant on a number of factors such as atmospheric and weather conditions and the power of the HF radio that is being used. Generally speaking HF coverage is up to 200 Nautical miles but under certain circumstances can be considerably more.
Certain Marine Rescue NSW Units maintain listening watches on 2182 kHz. Ask your local Marine Rescue NSW Unit for more information.
HF FREQUENCIES
Distress & Emergency Calling = 4125 kHz, 6215 kHz, 8291 kHz
Weather Forecasts and Warnings = 2201 kHz, 4426 kHz, 6507 kHz, 8176 kHz, 12365 kHz, 16546 kHz
Bureau of Meteorology voice = Daytime 7am - 6pm..... 4426khz & 16546khz
Night-Time 6pm -7am...2201khz & 6507khz
Anytime ......................8176khz & 12365khz
NOTE: The Bureau has agreed to allow State maritime authorities to transmit navigation warnings for a few minutes each hour on 8176 kHz. These transmissions by state authorities will commence at three minutes to the hour and must complete within 2-3 minutes, before the next 'weather' message is due to transmit (on the hour).
VHF Channel 67 available in the Newcastle, Sydney Port Kembla areas and scheduled to be broadcasted at 0733 and 1733 hours. Severe weather warnings will be broadcast at hourly intervals upon receipt of such warnings from AMSA and until such time that the severe weather conditions no longer exist.
Navigation Warnings HF 8176 kHz Navigation warnings are scheduled to be broadcast at 1057 and 2357 hours and at times that such warnings are received from AMSA. VHF Channel 67 Available in the Newcastle, Sydney and Port Kembla areas and scheduled to be broadcast at 0733 and 1733 hours and at times that such warnings are received from AMSA.
