When I was in Calgary, a local ham John, VE6KQ, insatalled a VHF 1200bps
regenerative packet repeater (DCD to key the repeater, so strictly packet)
and it made a tremendous improvement to the packet activity in Calgary.
Actually made the mode usable! I think someone quoted a four-fold improvement
in throughput. It certainly has it's advantages over a simplex system ...
if you can afford it :-)

The 19.2kB repeater has been working so well in Dayton that we're looking at
expansion to add a more user-oriented repeater. Our first thoughts were
1200 baud on 2M, but now we're leaning toward 1200 and/or 9600 on UHF.
A coupla questions:
1) In a moderately large metro area, does a 1200 baud 2M system get
saturated quickly? We were concerened that we'd get great coverage, but
that the thing would be 100% busy.
2) Has anyone successfully run both 1200 and 9600 on the same repeater
system? I seem to recall something about this, but can't put my finger on
the details. I hate the idea of investing in a 1200 baud-
only system...

It would be simple to implement but it would also recreate just the
problem we are trying to avoid: hidden stations. The 1200 b/s stations
would not detect 9600 b/s activity and visa-versa.

I don't know any of the details, but we have a 2m rpt in the LA area
that handles both 1200 bps and 9600 bps. At least I think so. I don't
have 9600 on the air yet. The call is wb6ymh and I bet you could find
out the particulars with a packet mail to wb6ymh@wb6ymh.#soca.ca.usa.na.

I'm working with Packet Radio from last month. Somebody say me what alternativesees
I have to work with TCP O/IP protocols in Packet Radio. Until now, I have
NosView installed. Another question: What TCP O/IP software for Windows can I
use?...
