level it is just all madness. It's just a hobby. I have a friend who shoots
off
model rockets. What's the point of that? I don't evaluate that hobby in
terms of, "Well, I could get in 747 and reach 20,000 feet much cheaper."
It's just not relavent.
Still, around here, there seems to be some movement, at least on the ax25
side, of justifying things in terms of 'emergency communications.' and
that some of the NODES and BBS's are installing backup power supplies
and things like this. This might some legs. Like I've heard of a goal,
to establish emergency links from City governments to some County
office in, err, Danville or something like that here in Alameda county.
And, maybe a backup network of some kind would be a way to do this.
That is to provide a 'backup' email link, so that when the net and
phone come down after a quake, that the offices that have emergency
power can email each other. I recall mention in some ham documents
somewhere that the Packet system in CA should be kept going
for some kind of emergency purpose, and I assume the emergency
power is the extent to which this is actually happening -- and that
is something I guess.
I find it moderately pleasurable to just poke around the NCA network
around here, and find that people still seem to be plugging away,
more or less in one form or another. I've been sending out
some packet email and receiving some email too lately. I think
these things are somewhat, what you make of them, and if you
seek out people to communicate with via PBBS mail, you'll find
them. Though it doesn't just happen without sending out some
messages. It doesn't really affect the quality of the communications
too much that messages take awhile to get through, though it
is annoying when they just disapear without bouncing.
Some of the EU people I talk to say that PBBS mail to the US
doesn't get through, though my understanding is that PBBS
mail to here in CA should work. (And it seems to go through through
the satellite or HF from the headers I see, so that' s kind of cool.)

Cheap old scanners are probably NOT going to work. Wide band scanners
are very
insensitive compared to commercial or amateur equipment. I've even seen
scanners
that distort the audio enough that DTMF tones are undecodeable.
MFJ makes a 220 MHz data radio, but I wouldn't recommend it. In the past
I was
partially responsible for a group of 5 MFJ VHF data radios; I couldn't
get them to
stay on frequency and 3 of their receivers were deaf.
Perhaps your best bet is to get some cheap amateur HT's to play around
with it. I
noticed that Jun's has ADI AT-400HP (70cm) HT's without batteries for
$120.
Good luck,

I use it less and less all the time...
The only permanent use that is left is to have a permanent telnet
connection to some friends, where topics of the day are discussed like
they would be on a local FM channel. Only these connections are too
long-ranged to be made directly, so they are made across a couple of
network nodes.
At least as long as this is still easily possible. The network nodes
now natively route IP traffic, so a permanent TCP session (between telnet
applications) is possible without any traffic when nothing is typed.
Sadly enough, other amateurs don't see the beauty of routing IP in the
network, and want to "upgrade" it to FlexNET. But FlexNET cannot route
IP, and forces you to use a surrogate: route it yourself and tunnel the
traffic through AX.25 connections that end up at another station that
routes IP. This would be a big step back, and probably the end of my
last use of the network.
The more we get away from a network that widely supports IP, the less
interesting applications are possible. So I just use the Internet instead.
Packet radio is a dead end anyway. Even with those "high performance
full duplex links" that operate at a blazing 9600 (or even 19200 or 38400)
bps, the network is slow compared to Internet.
Well, this is already being discussed in other threads.
Rob

Anybody know where I can get the download on the internet for WINPACK?
It is a pactor program that was popular before Airmail for e-mail .
Any ideas where to search? I got this program before but can't seem to find
it?
