RYA Short Range Certificate VHF/DSC Radio This qualification is required by many charter companies, including flotilla schools. There are legal requirements regulating to the use of Marine Mobile Telephony that require users to have an appropriate radio qualification, such as the VHF/Digital Selective calling (DSC) Short Range Certificate (SRC).

VHF Omnidirectional Radio Range  Mycket högfrekvent omni-directional range (VOR) är en typ av kortavståndsradionavigeringssystem för flygplan som gör det möjligt för flygplan  Very high frequency ( VHF) is the ITU designation for the range of radio frequency electromagnetic waves ( radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). VHF (Very high frequency) is the ITU term for the range of radiofrequency electromagnetic waves (radio waves) that are from 30 to 300 megahertz (MHz). Today’s VHF’s are not the same as those of 20 years ago.

Marine VHF (Very High Frequency) Radio comprises the radio frequency range from 156.000 MHz to 162.025 MHz. The International Telecommunications Union (ITU) labels this as the "VHF Maritime Mobile Band." Physically, the marine VHF radio is a combined transmitter and receiver, often called a transceiver. The PTT (Push to Talk) button located on the microphone or handset, controls which mode the radio is in at that moment. For normal handheld use (at five-watt transmit power), figure on a three-to-eight mile range from a small boat, compared to 15 to 20 miles with a fixed-mount radio (at 25 watt transmit power.) How much difference does increased transmit power make? Very little on the range of the communications. Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter.

Both Radio waves range from 300 gigahertz (GHz), or a wavelength of 1 millimeter, to 3 kilohertz (kHz), which corresponds to a wavelength of 100 kilometers.

Marine VHF (Very High Frequency) Radio includes the frequency range from 156.000 MHz to 162.025 MHz. The International Telecommunications Union (ITU) refers to this as the "VHF Maritime Mobile Band." Marine VHF radios both transmit and receive and are often called a transceiver.

VHF-radion fungerar både som telefon och kommunikationsradio. Det innebär att man förutom kontakt via telefonnätet, kan prata direkt med andra båtar i närheten, och även ha direktkontakt med Sjöräddning, Stockholmradio, broar, lotsar mm. Radio frequency range from 30 MHz to 299 MHz. The sub-bands most commonly used by fire are: VHF-FM Lo band: Frequency Modulation 30 MHz - 80 MHz, of which fire frequencies are between 30 MHz and 50 MHz. VHF-FM Hi band: Frequency Modulation 150 MHz - 174 MHz. This is the most widely used band by fire agencies. VHF-AM: Amplitude Modulation.
