Call
The initial voice message used to invite a reply (ie. Clubhouse, Clubhouse, this is Deepsea, Over)
Message
The information that you are trying to send (ie. Where do you want this racing mark laid?)
Standard Message Formats
During the course we will use specially adapted radios, which do not transmit, this allows us to practice all of the different types of alerts, calls and messages.
Please DO NOT practice these on 'real' VHF radios.
Below are the main four alerts, calls and messages which we will be using on the VHF course. It would be useful for you to revise the format of these calls before the course.
Mayday Message (Distress Alert)
This is when you get to press the red button! Enclosed is a listing of the Distress Alert, Call and Message format.
Ships Radio Licenses are issued in the UK by OfCom. See the OfCom Licensing Centre for more details [OfCom...]
Get to know our radios
On our course you will be using ICOM M421 VHF radios, you may wish to read through the manual to become familiar with how to use it.
Icom M421 Manual
Do not think you have to read every page of this manual (unless you have a lot of time on your hands!) focus on the first few pages to get a feel for the radio.
Pre-Course Assessment
Before the day of your course you will need to take the Pre-course Assessment to prove that you have learnt the basics.
