Re: DSC (Digital Selective Calling) Explanation

cburger,
The short answer is: No
You can still use the radio to talk on cruiser's nets, and ham radio operations (assuming you're a licenses ham?), as well as use it to receive all sorts of signals (WeFax, SSB Voice weather, shortwave broadcasts, etc.)...
And, of course if you're within range (~ 5000 miles of Mobile, AL) of WLO, you can still use the radio to make and receive ship-to-shore telephone calls....
{and, if you're within range of USCG's NMN or NMC....or AMSA, or NZ Maritime radio/Taupo....then you could still use your radio to call them on SSB Voice, as they continue to maintain an SSB Voice radio watch on a few frequencies...}

The long answer is....well it is long!
But, in the context of using a non-DSC HF radio to call / signal other vessels (or to call / signal the >80 HF-DSC shore stations, or the >450 MF-DSC shore stations, currently operating worldwide), then the answer is: Yes, it is no longer serviceable...and hasn't been since Jan 1999...


Please remember the GMDSS (Global Maritime Distress and Safety System) which mandated Digital Selective Calling (DSC) on both VHF and MF/HF radios (as well as 406mhz EPIRB's, INMARSAT-C, NAVTEX, and SART's), was implemented in 1992....and became mandatory for all signatory nations and all SOLAS vessels in Jan 1999...
So, this has been around / in use daily for decades now...



If you read this thread, from the beginning....and watch the videos, in their entirety....then you should be able to see that all of this is well explained...

I hope this clarifies things??
Fair winds...

John

You can use a software app to do DSC on an older SSB radio. It is called PersonalDSC.
