So, I was thinking, what with all the technological advances in
communications, why are we still stuck with VHF radios on our boats?
The limitations of VHF radio are obvious to all of us, so there's no
need to repeat them here. And I'm suggesting a move up to SSB or
satellite telephones.

Surely, there is a better way to handle boat to boat or boat to shore
communciations, with features like duplex, much greater range, less
static.
Right?


It would seem that the next logical evolution for VHF communications is for
it to go to a totally digital format, rather than the analog system it
remains. Digital will allow more available bandwidth for each frequency,
would open up the possibility of full duplex communications and would
provide clearer communications.

Aha! And I mis-typed above. I am not suggesting going to SSB or satellite.

I like the idea of full duplex VHF.

You can get it with commercial quality equipment (spelled mucho
dinero).

It already exists, but the radios are expensive.

I'd still lke to know why you think duplex is so important.

Try talking to my wife on a semi-duplex cell phone someday and you will
understand.

If Mrs. E is anything like Mrs. Wave, you aren't going to say anything
anyway which proves the point. You don't need duplex. :)

Given the crowded nature of the airwaves it would probably be BETTER to not
have full-duplex. If folks feel the need to prattle on endlessly let them
use cell or satellite phones... and PAY FOR IT. Stay off the VHF for that.
