Digital Selective Calling & Marine Radio: Taking the search out of search and rescue

[@springchecking427]

The acma should definitely do a documentary. About VHF repeater systems.
Explaining the fine detail of the equipment. running the old HF. and VHF network repeaters. Do a video documentary. Of the equipment..

Finally a perfect video on the DSC facilities of marine VHF radios. I hope to see great progress in using VHF-DSC radion on coastal waters of Australia.
If you wish to have an onboard reference and aide-memoire, you mignt be interested to get my "Marine VHF Radio Handbook" and "Marine VHF Radio Simulator" covering both DSC and voice procedures.

I'm doing this course on Friday unfortunately ive had no training apart from watching your video,
Can you give me an answer below is an email I required for my course I'll never work on a boat ever I don't even use a vhf radio I use uhf radio but if I don't complete the course I loose my job bit unfair, so my acessor has send below email but I'm struggling to think what he's asking for what my reply should be please 🙏 help
application form and some photo ID (Passport or Driving Licence).
Initially I will set you a few questions to check that you have still
retained the knowledge necessary to pass the written exam.
The main question is a distress scenario from which you have to produce a
Distress Call and Message.
for example:
Your vessel VIKING QUEEN callsign GGDF MMSI 123456789 is in position 54 degrees 33 minutes North, 002 degrees 04 minutes West.
Your vessel is on fire and you require immediate assistance.
There are ten people on board and gale force winds.
What is the Distress call, and message that you would transmit by voice
after sending a Distress Alert by DSC?
..........................................
Your answer should look like this:
Call
Mayday x3 this is VIKING QUEENx3 callsign GGDF MMSI 123456789
message
Mayday
VIKING QUEEN callsign GGDF MMSI 123456789
Position 54 degrees 33 minutes North, 002 degrees 04 minutes West
On Fire
Require Immediate Assistance
10 POB Gale force winds

Where can I purchase this radio?. Thank you.

[@jayytee8062]

You have to buy this then you have to have this and then that, but you first have get this number but to get this number you have have this card but to get this card you have to do this course but to do this course you have to pay a tidy sum.....bloody crap!
This is a rort first and safety last! Absolute thieves!

5:31 .....the nature of your distress. Wrong. ID and position only.

[@jackkennedy1133]

This is wrong in many ways. How can an automated signal tell the receiver of the signal what the problem is? No where does it say that conversations should be made on Ch70 after pressing the DSC button. No rescue station monitors Ch70 however they may change to Ch70 if a DSC call alarm is activated. This video really does need work

Hi Jack, thanks for your feedback about the DSC video. With a DSC-enabled radio, the way to include the nature of the problem in a DSC message is to either 1) input the problem if you have the time, or 2) if in imminent danger, just press the button for distress. After pressing the DSC button you should continue using radiotelephony channels. The DSC channel should only be used for DSC digital transmissions. This is explained in detail in the VHF Marine Radio Operators Handbook which can be viewed/purchased on the Australian Maritime College website at www.amc.edu.au/handbooks
