Onboard Pino we carry a fixed marine VHF radio, a handhelf VHF and two transceiver Walkie Talkie two-way radios. VHF/UHF radio waves travel in straight lines (line-of-sight) generally cannot travel beyond the horizon. VHF (very high frequency) is the designation for the range of radio frequencies from 30 to 300 megahertz (MHz)
A marine VHF radio is an important and reliable for bidirectional voice communication both for ship-to-ship and ship-to-shore. In Canada, a Restricted Radiotelephone Operator Permit is required to transmit, it is unlawful to operate a ship station that is not licensed. The handhelf marine VHF has the same functionalities as the fixed version, but is equipped with DSC.
We sometimes use the two transceiver two-way radios to talk to eachother from shore-shore, an Amateur Radio License is required to broadcast with this type of radio in Canada. A license ensures that new users are aware of the existing regulations and don't broadcast on reserved frequencies.
