What are you going to use when HF propagation is too weak to support
voice???

That was already answered higher up in the thread, I will requote that part:

The International Maritime Organization officially phased out Morse code Feb.
1 for ships in peril, replacing it with the high-tech Global Maritime Distress
and
Safety System.

So that answer would be, the Global Maritime Distress and Safety System.

Satellites and GPS are far more reliable than HF. Keep in mind code was
invented and used because there were no microphones invented yet.
Likewise, HF was ok before we had satellites and GPS. When a friend of
mine recently traveled overseas, I was able to track the entire flight from
several free websites that you just enter in the flight number and you get a
constant read out of speed, altitude, location and maps to show you exactly
where the plane was the whole time. With technology like this, no one even
needs to call for help anymore, when the signal stops, we know exactly where
it was when it stopped and can go looking for it.

Why do so many people want to throw all this technology away and force
everyone to stay with antiquated forms of communication like HF and Morse
Code?

What next? Will they start a movement to force all of us to get rid of our
washing machines and have to use old washboards instead so THEY will be happy?

I for one, gladly embrace new technology that makes life easier and
better. Wanting to play around with HF and Morse Code for a hobby to get a
nostalgic feeling of yesteryear is fine, but be realistic and don't come up
with ridiculous ideas to force others to use it.

People who bowl or play golf don't force everyone else to do that either.
Hams that use microphones don't tell morse code lovers they have to use
microphones, so why can't the stubborn headed morse code loving hams just
enjoy their hobbies without forcing everyone else in the world to do what THEY
want to do.
