It may be worth repeating that our ham networks can be
up-graded without replacing the entire system. The usual network
here in the mountain states has just a few nodes on 12,000 foot
mountains all on the same 145.01 MHz. Hidden transmitters are
rampent and the actual baud rate drops to 50 with just a little
traffic. But there are a few that make sense.
WY5G and KE5CI have been working with nodes at Silver City NM
and have some good ideas. Early on they were using both 145.01 and
223.4 MHz radios and 2 tnc's that were connected via the back-
plane. At their site there were zero hidden xmitters and the 1200
baud packet data flowed between AZ and NM at close to 1200 baud!
I have 3 frequencies at my home and all radios are connected
to tnc's that in turn are connected to my g8bpq switch. The
frequencies are 145.07, 223.4, 445.1 MHz. All 3 radio's can
transmitt without effecting another radio's reception. And all
three networks end here (there are no hidden xmitters). The 445.1
radio is a TEKK and it is operating at 9600 baud. It works just
fine and lets me send bbs forwarding to 2 other networks at the
same time.
So the message is clear. You can improve a great deal over
the norm by making a 1200 baud network actually work at 1200 baud!
And don't think getting a 9600 baud network up and running is
simple. There are no cook-books and the problems are many and
frustrating.
But doing these kind of projects will make net a lot more fun
to use and file transfers via ftp are fun at 9600 baud. This
winter will see me trying 2 TEKK radios, one at 423 and the other
at 445 MHz connected to jnos110x15 via 2 9600 baud tnc's. If this
works we will extend the network north about 150 miles...
Happy Holidays to you all...de k5di

Please, Karl, keep us up to date on that. I, for one, would be very
interested in the progress of your project. I'll be needing all the help I
can get in the next academic year.

Is there a gateway reachable from the Outer Banks of North Carolina,
specifically from between Duck and Kitty Hawk? I'll be at the beach with
my folks at a house they built in Southern Shores for week between Xmas and
New Years... trying to decide which toys to drag along.
Even if no gateway nearby, is there any IP activity out that way?

Well... I run the 44.74 gateway, and I can definitely say that it is down
right now. I have just started with a new company, and the connection
that did exist is quite dead. It should be up by mid March.

I don't know. There is very little IP activity here, and I doubt that
there is much that direction, but I may be wrong.
