Never have had a boat or Marine band Radio HF or VHF in all my life, nevertheless I enjoy videos like this one. 😃 I am a licensed Ham Radio operator - Extra. I like that M802, though. Hope you and yours are doing well in Florida. 😃 Greetings from Central Virginia.
First of all I would like to thank you captain for these incredible videos as they have helped me a lot at understanding and learning about one of the most common and basic equipment I will be using in my profession in the upcoming years. You see I am about to begin my first educational voyage on a cargo ship as a deck cadet. Apart from that I would like to ask you something about the frequencies. You said that the IC M802 has a built in function that is scanning only the 6 frequencies for distress,safety and urgency. Does that mean ,referred to what you said in the video, that even if one has the other frequencies he will not be able to receive messages from them because the M802 does not scan them?
Well, the answer is yes and no....sorry, I'm not trying to be a jerk, just need to further explain things? 1) The M-802 (and the new M-803, and all current Class E GMDSS MF/HF-DSC-SSB Radiotelephones) have a separate built-in, dedicated, DSC receiver that is always on (as long as the radio is "on"), always "scanning" the six international "GMDSS DSC Calling and Safety Frequencies" (2187.5khz; 4207.5khz; 6312khz; 8414.5khz; 12577khz; and 16804.5khz), using a separate "DSC receive antenna".... This is done in the background, without operator indication or involvement (until and unless you receive a DSC message/alert).... This separate, dedicated DSC receiver cannot be changed or disabled....it is always on and working....(which is why the M-802, and EVERY MF/HF-DSC-SSB-Radiotelephone, needs a separate, dedicated DSC receive antenna) This is separate from any other operations of the radio, meaning the main functions of the radio (and its main antenna) can be actively receiving and transmitting other messages / traffic, whether voice, image, or data, and/or it could be scanning some other frequencies, whether for voice, image, or data...or even scanning other DSC freqs, such as those originally designed/designated (in the late 1990's, before the advent of efficient PACTOR and/or inexpensive sat comm data) for "routine ship's business / routine traffic signaling, etc.....on any of its bands/frequencies, and neither of these functions will interfere with each other.... 2) The M-802, and many other MF/HF-DSC-SSB-Radiotelephones, can also scan other frequencies (using the main radio receiver, and main antenna), whether for voice, image, or data, DSC....and/or you can use the main radio (and main antenna) to transmit and receive (voice, data, images, DSC, etc..) on any of its operational bands/frequencies! SO.... 3) So, the answer to your questions is yes and no.... ---- Yes, the dedicated DSC receiver is dedicated to JUST those six international GMDSS DSC Safety and Calling frequencies (2187.5khz; 4207.5khz; 6312khz; 8414.5khz; 12577khz; and 16804.5khz) ----- No, the main radio can be used to scan, and/or receive, and/or transmit-n-receive, on any of the bands/frequencies it is designed to work on.... 4) Finally....all of this should be covered in detail in any GMDSS class and in any professional offshore mariners class.... These videos are designed for layperson sailors, on small, private vessels....who would likely never spend the money ($$$$) and time to take a GMDSS class/course.... These videos are not a substitute for professional training, for professional mariners.... :) But, I'm glad I helped! :)
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
Emmanuel, No, there is no fee nor any payment for any of this. (except you buy the radio, and if in USA pay a $200 US Gov't License Fee, every 10 years....which is very inexpensive.) The GMDSS (Global Maritime Distress and Safety System) was established by the SOLAS Conventions (Safety-Of-Life-At-Sea), to provide just what it says "Safety-Of-Life-At-Sea", and is paid for by the 160+ member nations.
Very informative, I like it great communication. Soper awesome quality.
Many thanks . Greetings from Hawaiian islands 🏝
Thanks. This is only one channel on YT with such great instuctable movies about DSC on HF. Suscribed!
Wow, thanks!
Never have had a boat or Marine band Radio HF or VHF in all my life, nevertheless I enjoy videos like this one. 😃
I am a licensed Ham Radio operator - Extra. I like that M802, though.

Thanks for this very informative video.
You're welcome!
Please be sure to watch all the playlists, for a great deal more!
Thanks
You're very welcome! Please be sure to have a look at the RUclips Playlists I put together with many videos like this. :)
Fair winds!

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
Can I set up a time to call you on SSB?
How do we decide the calling frequency?
is it required to pay for this service? Seems good to have free voice call over the globe (of course each have to get their own radio eqiupment)
