VHF Marine Band, marine radio, VHF radio, VHF radiotelephone or even "VHF marine [[CB]]" to [[CB_Savage|some people]]. Worldwide allocation 156-162 MHz. Several country-specific variations. In some parts of the USA, parts of the marine band is allocated to other services (either on a primary or secondary basis). Mixture of simplex and half-duplex (split-channel) allocations. Some channels used as repeaters in certain countries (Australia, New Zealand), as links to landline telephone system (defunct now) or crossband to other marine allocations such as [[CB#Australian_27_MHz_Marine_CB|27 MHz]] or [[HF_marine|HF marine]]. Like many other [[VHF / UHF Radio]] services, the VHF marine band is heavily pirated (or bootlegged) for non-marine land mobile purposes. It is especially popular with [[Hunt_Club_Frequencies|hunters]], truckers, logging companies and delivery services. While similar services such as plain old [[CB]], [[MURS]], [[FRS]] and [[GMRS]] exist to fill these needs, the VHF marine band continues to suffer from misuse, especially away from water where enforcement is difficult. So common is VHF marine usage by hunters that it has earned the nickname "The Bambi Band". Although, in the late 2010s, the number of hunting clubs switching from VHF marine to [[Business_Radio|licensed FCC business radio frequencies]] is [[Hunt_Club_Frequencies|steadily increasing]], probably more because of interference issues and less because of [[FCC]] [[Bust|enforcement]]. Internationally, the VHF marine band is set up for either single frequency (simplex) or split-frequency (duplex). On duplex channels, the higher side is the "B" channel, the lower/simplex channel is the "A" channel. VHF marine radios set to "USA mode" operate in simplex mode only, making all channels "A". One will often hear a channel referred to in this manner "channel 22A" for example, simply means channel 22, simplex. The 156.000 MHz to 156.250 MHz region is shared with Part 90 land mobile in certain parts of the United States. This comprises public safety allocations from 155.9925 MHz to 156.2550 MHz (7.5 kHz steps). This overlaps with VHF marine channels 01, 02, 03, 04, 05, 60, 61, 62, and 63. In some areas, land mobile allocations are prohibited above 156 MHz to prevent interference with VHF marine communications (for example, in the New Orleans area, in certain Canadian border regions, etc.) ===VHF Marine Channels - USA Channels - US Channels New and Old Channel Numbering=== 4-digit channel numbers for simplex frequencies...some channels are still two-digit. USCG recommends use of the 10xx channel designators for the old A designators for simplex channels (for example, 22A becomes 1022). Under the 4 digit channel numbering system, the B channels are re-designated under 20xx series. In other words, channel 27B becomes channel 2027. Since the vast majority of US marine traffic is simplex, it's simply a question of renaming the "A" simplex-only channels. Channels that have always been simplex - such as channel 16, etc. retain their two digit designators. {| class="wikitable" ! New Channel Number ! Old Channel Number ! Frequency !

However, some or all of these channels are available in USA mode in many VHF marine radios as simplex channels. Use is usually commercial or non-commercial ship to ship / intership. Channels 84, 85 and 86 are still technically and legally allocated for duplex use only, but many radios sold in the United States include 84A, 85A and 86A as simplex channels in addition to 87A and 88 (or 88A) as simplex ship-to-ship channels. These channels - 84A, 85A and 86A, as well as 87A and 88 (or 88A) are often used by recreational boaters, fishing fleets and various other non-commercial and commercial uses. Older-generation VHF marine radios may only allow simplex use of channel 88. Other radios allow simplex use of channels 88 and 87. Older-generation VHF marine equipment is also more likely to have channels 60, 61, 62 and 64 available as simplex channels. Newer equipment may or may not include channels 84, 85 and 86 as simplex channels in USA mode. Channel 01A (1001) and 05A (1005) are only available for use in very specific areas. These channels are used nationwide for commercial and non-commercial (recreational boats) intership communications outside the VTS zones. {| class="wikitable" ! Channel ! Frequency !

Weather channels 8, 9 and 10 are only used in Canada. Channels 24-28 and 84-87 were allocated for "coast station" (radiotelephone) services but these are no longer used. In some countries VHF marine continues to operate as a duplex system, with certain areas implementing repeaters (Australia for example). In other countries such as the United States, the 161 MHz high side ("B" channel) of the duplex pairs for these channels (161.800 - 162.000 MHz) have been re-allocated to other services, including [[Business_Radio|land mobile radio]], public safety systems and [[Nationwide_Public_Safety_Interoperability|reserve/emergency interoperability frequencies]]. In some countries (including the UK for some channels) semi-duplex is used for ship-to-shore communications, even though no operational benefit is gained using duplex vs. regular simplex. Land mobile users of the 157.2 MHz to 157.4 MHz and 161.8 to 162.0 MHz frequencies are still licensed as Radio Service Code PC - Public Coast Stations, Auctioned. A licensed user will acquire a block of frequencies as well as a market area. For example, instead of being licensed for 157.2 MHz and 161.8 MHz, a user will be licensed for 157.18125 MHz to 151.20625 MHz and 161.78125 MHz to 161.80625 MHz. This practice is common in areas where the VHF high band is used for wide-area trunking systems, often for public safety or law enforcement purposes. The 160.2 MHz to 161.64 MHz portion is allocated for use by railroad systems in the United States and Canada (NFM voice and NXDN digital voice/data). In other countries, a mix of simplex and duplex channel plans are used. The duplex (or B channel) is + 4.6 MHz offset from the A channel. Not all channels are used in duplex mode in all other places, and simplex use is extremely common (as is the US standard of simplex only). The FCC permits use of the shared marine frequencies discussed in areas away from the coasts and major waterways to avoid interference. Channels 24-28 and 84-87 are officially still allocated to duplex radiotelephone and VHF Digital Small Message Service data services but are heavily used for analog voice communications, usually non-commercial in nature. Channel 70 (156.525 MHz) is used for Digital Selective Calling (DSC) and voice communications are not permitted. 156.800 MHz - VHF marine channel 16, is the international VHF distress, safety, and calling channel.
