With that dedicated group with common interest, one can indeed
build a working network spanning hundreds of miles. No, it is
not cheap ... but it can be done, and it HAS been done. Part 15
devices are totally useless for this kind of network.

I'm not familiar with part 15 devices what are they? Also would they allow a
storm chaser to pull over 20km out of town, pull out their laptop and login?

Nope. Neither will 56k. You're talking very wide channels with no FEC.
Range without beams is very short. Use a TV station as an example.
Very high power, 6 MHz bandwidth. How far can you see the megawatt
station reliably? Not far enough...

5 miles is emergency communications around here. Makes a
great repeater link (data, video, and voice).

I agree. BBS is a low baud affair. Higher speed is unjustified.
> "Part 15 devices: Very limited short range plug and pray."
Not very original, and not very true. Long range at high bit rates
is different than long range at low bit rates.
Either mode is purely pluggable, neither requires religious
devotion.

Part 15 network cards can be had for as little as $120(maybe less).
Getting hooked up to DSL/cable modem is going to cost you that or more
just to start - and then $39.95/mo thereafter.

The WWW is a joke on society, it will never last.

Hogwash. I had 5 users running 33k 24hr/7day links on a
64k link. It's what you do that counts. If you want to steal
music or files on Napster, etc, then yes, stealing takes a lot
of bandwidth. Rather than pay big bandwidth bucks to
steal, you could go with a 9600 baud modem, and go buy
the fricking CD.

Who do you mean then? All those homeless hams out there? It always
gets me that hams will spend over $1,000 for a rig (or $2-3 thousand
more than that for very incremental improvements offered by a fancier
rig), ditto antennas, but then will pass up the digital modes due to a
few hundred bucks required for a TNC or similar controller. Sure, $80
bucks is a lot of money to some people, but frankly, it isn't much
compared to the amount of dough most active hams spend on the hobby.
Noise level stuff.

There is another maker of these PSK31 interefaces that is cheaper though has
less functionality.

Also the Rigbalster is extremely well made (IMO), and does exactly what its
supposed to. Worth it thats up to you.

My $US10 interface does that -- the PC is connected to the accessory
socket on the radio.
$80 may be a reasonable price given all of their costs, reasonable
