VHF Radio
Introduction
Marine VHF radio is a worldwide system of two-way radio transceivers (transmitter-receivers) to provide voice communication from ship-to-ship, ship-to-shore, and ship-to-aircraft. It uses FM channels in the very high frequency (VHF) radio band which is between 156 and 174 MHz. This band is designated as the VHF maritime mobile band.
The Club has a VHF transceiver (base station) in the signal tower. The Club also has several hand-held VHF transceivers.
The Club uses Channel P4 (161.425 MHz, also known as M2) as this is one of the channels set aside for matters relating to mooring, berthing and race control. Importantly, it is not necessary for the operator using this channel to hold an operator's certificate.
In the event of an emergency where there is a risk to life, a VHF radio may be used by any person to summon assistance. This means that, in an emergency and whether you hold an operator's certificate or not, calls could be made on the distress, safety, and calling channel (Channel 16 - 156.800 MHz). Before using Channel 16 afloat, bear in mind:
- Club protocol is to for the Race Officer/Shore Coordinator to contact emergency services by phone.
- If the situation requires you to make the call while afloat, refer to the emergency radio message card displayed in your patrol boat (see below).
Fundamentals of VHF Operation
Before the start of the 2023 and 2025 sailing seasons, Jenny Chilvers, one of the Club's RYA Senior Instructors, gave talks on the fundamentals of VHF radio operation. These were aimed at providing some familiarisation with Club equipment and to encourage the use of correct procedures. They were informal sessions; they were not RYA training nor did they lead to a qualification.
The slides that supported these talks provide an excellent introduction to VHF procedures. They are available here.
Club VHF Users' Guide
Guidance for the Duty Crew is contained in the Club's Standard Operating Procedures (SOP). The guidance refers members to a VHF Users' Guide (here). This guide is reproduced as an Appendix to the SOP.
Emergency Radio Call
As stated above, Club protocol is for the Race Officer/Shore Coordinator to contact emergency services by phone. However, if you become aware of an emergency and you are unable to contact the RO/Shore Coordinator, you should make a call in accordance with the Emergency Radio Call below. Such a call will be heard by the coastguard and any vessel/aircraft in the area that is monitoring Channel 16.
The Emergency Radio Call is on a card which is held in each patrol boat. It also appears within the Duty Crew Guide for patrol boat crew.
