That's a constructive proposal.  To me, I think to
get people interested, ideally, this kind thing would have both
a 'practical use' and a 'hobby use.'

Do those telescoping masts, that TV Stations use on their
vans ever end up surplus?  You know, the gadgets, where
the little dish gets raised up in the air from a van, to talk
back to the station I guess.  I assume ideally, you'd have
that or some kind of remote antenna you could hook up, and
then a mountaintop site, with a repeater -- that could link
to somebody's house with a cable modem or something.

I did talk to some hams on wwconverse from Turkey, and they
said that they setup some kind of remote link to the parts
of Turkey that were destroyed by the quake.  Not sure what
kind of equipment they used.  So, I don't think this kind
of thing is too out of the question.

Me, I'd think maybe little easier would be to setup an 'emergency email'
system -- so that you'd setup a table with a bank of laptops
running on emergency power at the emergency site. And,
then people who had messages to send could sit at one of
the laptops, and type in their message -- which would
then relay out to somewhere that had an internet connection.
Maybe then a printer and a bulletin board could handle incoming
traffic.

Sounds like a job for the ARRL.  They're the only ones making money in
Ham radio. They've never been much interested in data though.  But if you
want a national network, you are not going to do it without them.  What does
the West Gulf director think?  What is his budget for this?

Blow me.

I'm saying that Hams have abandoned packet radio because the data that is
being transported is of little value.  If Hams won't participate at 1.2 kbps
reading
and writing this junk, why would they suddenly read and write it if the baud
rate
were 1.2 Mbps, or the protocol was a bit protocol, or a byte protocol.

I'm not denigrating anything.  I just don't see the logic.

Blow me.

OK, well if host to host communications are dying faster than hogs at
a slaughterhouse, I don't see data communications growing, outside of
fascilities to voice communications.

Blow me.

I'm saying that given that Ham radio is limited in free speech content, and
Public radio is not, why choose Ham radio over Public radio??  I can
say "the seven FCC non-words (shit, cocksucker, motherfucker, and tits)"
and show mammary glands on Public radio infrastructure (Part-15), but I
would be fined or lose my license for those words and pictures on Ham radio.
It's obvious to me which one has more freedom and function, even for those of
us who don't collect mammary gland or hydraulics photos.

Blow me.

Shit, Hams are too cheap to buy a good HF protocol that is available now.
You have to buy this stuff, because it takes an engineering degree to
understand
the DSP functions, and algorithm required to achieve the transport.  You can't
homebrew something you can't understand.  It's not resisters and capcitors
anymore.  You really do have to know how to A/D, D/A, and do digital
DSP based algorithms.  I know Hams who can do DSP without an engineering
degree, but they have equivelant knowledge to what is taught at the
undergraduate
level, more-so actually, as most undergraduates work with Matlab simulations,
and  not real hardware.

Blow me,

What's a "LandLine Lid?"  Sounds like something a CB radio
person might use?  10-4?  Good-Buddy?

> Thanks, Steve!

Blow me,

You're welcome.
