lol - Poly - you did your course before Clyde closed down - if I am not wrong ! so your question was NOT a question!

but ...

group calling - you can't physically add stations to Group - A Group MMSI is issued from ofcom and each radio is programmed with that number to be part of the group.

So to answer your question - you can't add the all coastguards to a group. For this to happen the coastguard would have to be part of a group in first place that Ofcom had issued , by entering thud group number into there radios and you had to call them a pre-determined group number.

transit report -

by voice

A.

whatever coastguard , whatever coastguard
this is your name , your name
routine
over

the coastguard will tell you to go to 67 and standby
you say going to 67 and standing by...

move to ch 6 7

B.

wait till coastguard to call you

Whatever coastguard , your name

just letting you we have x number people in board, we are going to x or doing y we expect to be off the water by time , you hold my cg66 over

they will acknowledge you tell you let them know when off water and have a nice day over

then I would say will do - thanks - listening to ch 1 6 - out

wait few seconds then go back to 16

if using DSC - place individual call to coastguard and they will switch you to working ch usually 67 automatically. then follow above B.


Hope I not missed anything - typing on iPhone lol!

Interesting reading this thread, Im about to do the course in a couple of weeks. Hopefully it will answer the questions raised.

Ive got the radio, just need an antenna and then Im ready for it.

How do you get your MMSI number, do you have to send off your cert. once you have passed the course ?

You will get your Radio licence from Ofcom

Ofcom | Ship

No you do not need a Short Range Certificate to get a Radio licence

If using DSC to call the coastguard they will switch you to their working channel. At that point I would call them again on the new channel, not wait for them calling me. Should I wait for them to call me?

Never actually called the coastguard (CG) via DSC as I always use a marina (or Portsmouth QHM, or another boat) for a radio check. It seems wrong to tie up the CG on a routine call if you are calling someone else anyway, and can just ask them at the end of the call if your "transmissions are good and readable".

Does anyone actually regularly use DSC? We've had a RIBnet group MMSI for the best part of a decade but as far as I know it has never been used by anyone. Maybe there are enough DSC radios out there to make it worthwhile now?

Just a quick heads up on the test procedure for radio check.
It is recommended that you carry it out to the CG, firstly on Low power and if unsuccessful, High power.

There are a number of reasons that we to test to CG,
1. Its the CG that your will want to reach when you are in trouble, not an adjacent craft - Mayday relays get messy when unnecessary.
2. CG record correspondance, so in adherence to your ships licence, you are recorded as carrying out your radio test (you still record on your ships radio log)
3. The CG can be busy, and be sympathetic if you hear they are busy, but Radio Checks are part of their remit, and don't feel like your routine calls are a hindrance, Routine calls including filing a TR are the bread and butter of CGs

Now, I appreciate you are probably in much busier waters than I, and that radio chatter can get quite busy, and also in the event of an incident that you may be surrounded by other craft to offer assistance. But under the european CEPT radio licence, the CG are who we carry out radio tests to.

DSC wise, I know over here there is very little use of it by mariners, but we still instruct people to use it, integral part of the VHF SRC 2 course, and I gotta say, big fan of the instructions "If donegaldan falls out, press and hold the red distress button" !
I know the CG will move you to a working channel after calling them using DSC, but you at least have verified the digital component of your radio, thus testing it fully.

But if you get tied up in all the rules and regs you could kill a whole day testing

The position Poll feature is quite neat, if you are in the same stretch of water, and want to know where your buddy is... Saves calling it out over the radio, and if automatic response is setup his set will just respond, can be nice and quick to find a buddy in a busy bay.

Also BIG fan of the the "Distress button" for visitors aboard my craft...
If anything should happen me.....

I'm not convinced that red button will be much use for a coma induced by a surfeit of sandwiches, crisps and venison burgers...

Now you can't beat a good old "bambi" burger from Jura....
Especially if she comes off a BBQ after being at sea all day

Great post Dan

Once again this shows the important of listening to the advice of an "expert" which you clearly are
