Re: Going DIGITAL!

Gee, Bob,

I think you should consider yourself lucky that the traffic you heard passed
was in voice and not CW.  After all it wasn't too long ago that many ops
didn't think it was 'formal' traffic unless it was CW.   And you know what?
The same arguments you made were being made about voice.

DIGITAL HT's???  I've yet to see a digital ham radio.  No I take that back,
I did see an article in QST on someone experimenting with spread spectrum.
All the ham radios I am familar with are analog.  I KNOW what you were
trying to say, jus pointing out that we're no where near the current state
of the art.

A "720K" floppy?   what's that?   My PCs only reads those Gb microdisks.
Oh, I've got one of those hugh old floppy drives that reads the old 2.8MB 5
1/4" discs (Just kidding here, I've been working with floppys since they
were 8" and only held 128KB.)  But seriously I haven't seen a 720K drive
capable PC in some time.  I did see an IBM Jr in the Smithsonian though.
Didn't it use 720K floppies?

Just like voice isn't everybody's cup of tea, packet isn't mine.  (at the
moment).   What about newer things like PSKI31?   There's better stuff than
this older packet technology you're talking about.
