This handbook is a guide for operators of coastal and vessel radio. stations including operators of VHF very high frequency and SSB single. sideband also called MF HF radios It provides information about. how search and rescue is managed in New Zealand, distress urgency and safety calls including appropriate use of cellphones. radio telephone procedures,useful contacts and terms. Maritime Radio, For seafarers their vessel s radio is their main lifeline to land. Maritime New Zealand s Maritime Radio Service Maritime Radio is. responsible for maintaining VHF and HF radio services for New Zealand s. coastal waters and much of the South Pacific Ocean and Tasman Sea. The services it provides include monitoring radio frequencies for distress. messages 24 7, The region covered by the New Zealand Distress and Radio Safety Service.
is known as NAVAREA XIV and includes 12 5 percent of the Earth s ocean. surface It extends from the middle of the Tasman Sea to the mid Pacific. Ocean and from Antarctica to south of the equator, This handbook This handbook is a guide for operators of coastal and ves.

120 180 120, Maritime New Zealand MNZ is also responsible for broadcasting. Maritime Safety Information MSI within the NAVAREA MSI includes. meteorological information coastal and oceanic navigational warnings. ice accretion warnings and ionospheric prediction forecasts. The service provided by MNZ is complemented by a network of. volunteer private radio operators located around New Zealand and its. offshore islands The network is monitored at all times by staff working. at the Maritime Operations Centre MOC co located with the Rescue. Coordination Centre New Zealand RCCNZ in the Hutt Valley. The Maritime Radio Service comprises 30 coastal VHF stations Of these. stations 28 provide VHF radio coverage throughout the coastal waters. of New Zealand The other two stations provide VHF radio coverage in. the coastal waters of the Chatham Islands There is also an oceanic. MF HF radio station located east of Lake Taupo, All stations are linked to the MOC It coordinates the transmission of all. MSI on voice HF and VHF as well as navigational warnings broadcast. over the Inmarsat SafetyNET satellite system The scheduled broadcast. times channels and frequencies are shown on pages 46 48. The MOC also provides these services to mariners, telephone patch and message relay facilities for search and rescue. and medical purposes on VHF and SSB,4 MARITIMENZ GOVT NZ. reception and processing on VHF and MF HF SSB of,trip reports TRs.

RADIO HANDBOOK 5, The RCCNZ is responsible for coordinating all major aviation and. maritime search and rescue missions within the New Zealand search. and rescue region SRR The region extends halfway to Australia halfway. to Chile and from south of the equator to Antarctica. RCCNZ is also responsible for coordinating land based missions when. an emergency position indicating radio beacon EPIRB or personal. locator beacon PLB is activated, All search and rescue efforts coordinated by RCCNZ are called. Category II incidents These incidents arise because an aircraft vessel or. person is in distress and often require national and international civil and. military resources There are at least two fully qualified search and rescue. officers SAROs on watch at RCCNZ at any time, The New Zealand Police are responsible for coordinating Category I. incidents which include many maritime search and rescue missions. close to shore Category I incidents also include land based search and. rescue efforts that do not arise from a distress beacon being activated. RCCNZ frequently provides support and advice to the New Zealand. Police during Category I search and rescue incidents. Further information about RCCNZ can be found on Maritime New Zealand s. website at maritimenz govt nz If you need advice or assistance. freephone 0508 472 269 or email rccnz maritimenz govt nz. RCCNZ is also the repository for 406MHz emergency beacon. registrations Registration is free register at beacons org nz registration. 6 MARITIMENZ GOVT NZ,HOW RADIO WORKS,Radio waves, Radio transmitters work by supplying a rapidly changing electrical current.
to an aerial antenna to create a changing electromagnetic field The. speed at which these currents change controls the speed at which the. electromagnetic field around the aerial changes This is measured in. 1Hz 1 hertz 1 cycle per second,1kHz 1 kilohertz 1 thousand cycles per second. 1MHz 1 megahertz 1 million cycles per second,1GHz 1 gigahertz 1 billion cycles per second. Consider the image of a pebble dropped into a pond with the pebble. representing the transmitter The radiating ripples represent the. fluctuating electromagnetic fields These fields are called radio waves. and they radiate out from the aerial at the speed of light. Marine VHF radio operates at a frequency of approximately 156MHz. while MF HF single sideband or SSB radios operate at frequencies from. about 2MHz to 22MHz,Frequency characteristics, The different frequencies have different characteristics for specific. purposes and are subdivided into bands,RADIO HANDBOOK 7. Frequency range Band classification Band abbreviation. 10 30kHz Very low frequency VLF,30 300kHz Low frequency LF.
300 3000kHz 3MHz Medium frequency MF,3 30MHz High frequency HF. 30 300MHz Very high frequency VHF,300 3000MHz 3GHz Ultra high frequency UHF. 3GHz 30GHz Super high frequency SHF, VHF radio waves travel in a straight line and do not bend to any great. extent over hills headlands or the horizon VHF radio is used for local. transmissions but aerials must be in sight of each other meaning they. have line of sight, MF radio waves have a greater tendency to follow the Earth s curvature. They suit medium range navigational aids regional broadcasting. and medium range communications because they can travel around. obstructions and over the horizon, HF radio waves do not bend over the horizon but use a layer of the.
Earth s atmosphere the ionosphere to reflect radio waves back to Earth. The ionosphere s properties vary throughout the day but it is most stable. shortly before sunrise and just after sunset These are particularly good. times for SSB communications in the HF band, During the daytime SSB transmissions are not as reliable due to. the sun s effect on the ionosphere In general higher frequencies such. as 12MHz or 16MHz achieve better communications during daylight. while lower frequencies such as 4MHz or 6MHz work better at night. The distance between stations is also a factor with higher frequencies. 8MHz and higher providing better results at longer ranges. 8 MARITIMENZ GOVT NZ,Simplex and semi duplex VHF radio. Simplex means both stations use the same frequency for transmitting. and receiving All channel 16 transmissions are simplex. Simplex radio,A B Direct communication possible,A C Direct communication not possible. Semi duplex uses a third repeater station normally located on a. mountain or similarly elevated location The repeater receives the. incoming signal and simultaneously retransmits it on a different. frequency To do this semi duplex uses two frequencies one to transmit. and another to receive through a repeater,Semi duplex radio. A C Communication possible via repeater, Because VHF signals will not pass through land masses a repeater.
may be placed on a hilltop so that stations on opposite sides can. communicate with each other By elevating the repeater station vessels. up to about 70 miles apart can communicate even though the line of. sight between the vessels may be less than 10 miles. RADIO HANDBOOK 9,Aerials antennae, The approximate distance in miles from an aerial to the horizon is. calculated in this way,Distance 1 2 aerial height metres x 3. Note the aerial height in the formula is the height above sea level. Two aerials will be in range of each other when their distances overlap. Not all aerials radiate power equally in all directions and a single whip. dipole aerial mounted vertically at the vessel s masthead will usually. provide the best 360 coverage, Aerials should be positioned to avoid being shielded by superstructure. masts and similar structures that could interfere with the radio waves. as they radiate from the aerial The masthead is usually the best. location because aerials are less prone to damage there and the range. is maximised,10 MARITIMENZ GOVT NZ,DISTRESS CALLS, Channel 16 is the international VHF channel for maritime distress. and hailing calling,Distress urgency and safety calls.
Special calls are used in cases of distress urgency and safety and. must be properly understood and used, DISTRESS the radio telephone distress signal MAYDAY is used to. indicate that a vessel aircraft or person is in grave and imminent. danger and requires immediate assistance, URGENCY the radio telephone urgency signal PAN PAN is used to. indicate that a vessel has a very urgent message to transmit about. its safety such as loss of steering, SAFETY the radio telephone safety signal S CURIT pronounced. say cure ee tay is used to indicate that the calling station has an. important navigational or meteorological warning to transmit. Communicating distress, A station in distress may use any means at its disposal to attract. attention make its position known and obtain help, Use of MAYDAY is prohibited except to indicate distress.
The distress call has absolute priority over all other transmissions. All vessels and coastal stations hearing it must immediately cease all.
