We'd probably use DDCMP to get it to the async level, right?
Maybe. I know that AX.25 has a protocol ID byte that specifies the packet
type being piggybacked - I'm pretty sure IP is 0xCC. It might be that
someone has already implemented a DECnet payload, but it's a long shot.
We could build our own TNCs that spoke 1200/9600 baud AX.25 on one side
and DDCMP on the other. All it really takes is some firmware... That'd be a
really cool gizmo, and completely useless to anyone except for a couple of
people to boot :-)
Realistically, a smarter thing might be to try WiFi. I think the current
distance record for WiFi is something like 250 miles; how far is between you
and Steve?? Of course, you'll need some pretty tall towers...

The KPC-3 is still a current product - HRO sells 'em for about $200.
They're the defacto standard for hardware TNCs these days. However I think
most people do it with a sound card and software (the ham radio equivalent
of a winmodem). And I'm not sure how many people still do packet as such -
modes like psk31, WSPR, JT65, etc are more common these days.
I've learned a bit about some of those modes...VERY interesting stuff. I've done a few PSK31 QSOs (sound card method) and have enjoyed it very much. I'm going through a Yaesu FT-920, on 40m.
For a better time reference, until the past year, the last time I was active in ham radio was the early 1990s. My how things have changed!
I didn't know hardware TNCs were still being made. That's reassuring. Most of the ham radio world, especially the "appliance operators", seems to have little problem with the idea of replacing EVERYTHING with a Windows box. *barf*
I have a pair of AEA PK232MBX TNCs. I might try to bring them up.
We should take this offline. This is not really HECnet related.
If you guys actually try to do DECnet over radio I'd be interested...
I think it'd be interesting to attempt. We'd probably use DDCMP to get it to the async level, right? (this could certainly be HECnet-related!)

rig to make this permanent.

Who is handling allocations out of net 44 nowadays?
Want to do some testing, when things calm down? I can do HF or VHF.
(or microwave, given some time...I have a strong interest
there, and lots of gear)

I still like the idea of UUCP / POTS links. IIRC, Sampsa or Steve had something going along these lines a while back. Not sure if it ever got off the ground?!?
I would attempt this if I had modems that weren't just soft modems. Might be able to use them if any of you know of any nice software for use on a BSD with them.
Update: I have 2 modems to try from that I can find
1). A winmodem
2). A Conexant HSF modem
who thinks I can get one of these working in MS-DOS? MS-DOS on a HT P4 with 1G RAM anyone?
I know it's not a UNIX but maybe the driver will show me a serial port I can attach a simulator to?
Toss the Windmodems in the trash...that'd be a good start.
I will, once I get something better.
Then grab any and all Telebit Trailblazer-family modems you can find.
They spoof parts of the UUCP protocol within the modem, which makes for
VERY nice UUCP-based news feeds.
I will use the winmodems until I find those/have the free cash to grab one. ;)

Count me in as interested. (I am also part of the informal uuhec uucp network already established).
Count me in for UUHecnet as well. Happen to have any dial in-capable systems Fred? I just got my modem working and you're in the same state and it might cut down on long distance. ;)

Was this UUHecnet? I saw a web page about that. Is that going
anywhere? If so, count me in!

No objections here. Mailman could also give us pipermail archives.
Seconded. Mailman is good. I dumped Majordomo about ten years ago
for Mailman. I run half a dozen lists on it here.
