Subject: 230.4 kbps system h/w available
After many years of development and use, it looks like my moderate
speed (230-500 kbps)
packet hardware system is looking for a new home and caretaker. This is
hardware assocated
with the system described in the ARRL Computer Networking Conference
proceedings:
system:

It has been in use in Northern California over the area
http://www.sonic.net/~n6gn/local/map3.gif
for about 10 years buthas recently been taken off the air and Internet.
I am now finding
myself moving on to other things and it seems a shame for useful
hardware to sit on the shelf.
The system consists of:
RF Hardware
Six complete:
radios, described above
antennas, yagis as above
Ottawa PI2 digital interface cards, described above
cables, radio->ECL/TTL_interface and ECL/TTL_interface->PI2
Some 9913 antenna Coax is probably available too.
Host PC's
previously running DOS/KA9Q but now running Linux to host the
PI2 cards and nodes as well
as internet services are also available. It should be noted that
due to a PI2 card-host
interface issue, older motherboards as on 486's tend to work
best. So even if you have
newer hardware to run on you might want to consider at least a
couple of these just to
have a running link or two as you bring up the rest. See the
PI2-users distribution
list for details on this known problem.
Over the last several years the system has handled many gigabytes of
traffic over a ~100 mile network
of paths and is capable of handling many more. The 10 watt radios along
with the simple yagis can
each support 50 mile or longer hops and the combination might make a
good backbone system for handling
both conventional AX25 as well as TCP/IP traffic over a wide area. We
have hosted web pages, run a
wide variety of tcp/ip applications, games, digital telephony, remote
access/control over the system
and with the combination of speed and Linux 'development' environment
many interesting uses
yet remain to be discovered.
I am interested in selling the hardware but also in seeing it continue
to be put to good use
in amateur service. While the system has been working fine, installing
and maintaining a
modest speed, wide area network requires effort and some expertise
(which can be learned) in
a variety of areas including propagation, RF hardware, digital
interfaces, operating systems
and networking concepts in general. It should not be taken on by
somebody who only hopes to get
a turn-key wireless network at a bargain price.
If you are interested in this system please contact me at
n6gn@sonic.net and I'll be happy to discuss it further.
