I don't know how it is up there in the Frozen
North but here in the US our
"300bd restriction" is very often misunderstood. We are allowed a symbol
rate of 300bd. Not a data rate. If we can jamb 1.2mbps into a 300bd symbol
rate we could use it.

And there is still an extensive packet network, with more nodes being
deployed, in fact, there seems to be a resurgence of the mode, as folks have
mentioned...but I have dropped my hardware TNC's in favor of software
modems that are more robust, less current drain, less birdies, and options
that were only dreamed about back in packets hey-day thanks to uz7ho,
uronode,bpq,FBB, Direwolf to name just a few...and these are actively being
maintained..in fact, I may have forgotten a few others...packet is alive
and well, and not just as aprs nodes...and with the advent of very
inexpensive computers like the pi, arduino, etc etc, it's a LOT of fun and
I see a lot of newcomers, even on slow old 300 baud HF daily...there *has*
been experimentation with higher data rates on HF, but our archaic laws
prevent us from going much faster than 300b on HF...9600b *is* doable on
HF, but not legal below 28mhz...that law needs to be revised, hi hi!
(and yes, TCP/IP also works on HF, but painful due to low 300b
restriction)
Cheers,
John

Yes I have an SCS Tracker and yes it too can do 9600 baud..
A lot of miss information going on here...
That's two TNCs... Still in production.... Any more probably...

I'd LOVE a 9K6+++ modem but they just don;t
seem to be available.
SCS TNC tracker (
http://www.p4dragon.com/en/Modems.html#widget4) and
the
sound card modes such as DireWolf and UZ7HO now claim to support
19,200 so 9600 should be doable.
