Four nodes are operational.

One 9600 experimental link utilizing the soundmodem driver under the linux operating system and a TEKK KS-960 radio on 70cm..  We are collecting data on link performance while adjusting operating configurations.

Two 1200bps links.

An Icom-3200 with a Kantronics KPC-3 on 2 meter.
An Azden PCS-2000 with a kantronics KPC-2 on 2 meter.

One Icom-760 operating on HF at 300bps via an AEA PK232.

Of course, when your base of operations is on a riverfront (read, at sea-level) a tower becomes a necessity.

A 9600bps link running off of a TEKK KS-960 utilings the soundmodem driver under the linux operating system on 70cm. 

A 1200 link running off of an Icom HT on 2 meter utilizing the Baycom driver under the linux operation system.

A 9600bps link running off of a TEKK KS-960 utilings the soundmodem driver under the linux operating system on 70cm.  Soon!

A 1200 link running off of an Icom HT on 2 meter utilizing the Baycom driver under the linux operation system.  Soon!
 
 

For now all work will remain in the Amateur Radio frequency allocations.  Our compressed traffic will tunnel through the existing amateur radio networks.  In exchange for thier hospitality, our nodes will also pass Amateur radio AX.25 and TCP/IP traffic. 

It seems that a revival of TCP/IP over radio links resulted in the ousting of a few local domain administrators, and since thier removal I have finally been assigned ampr.org addresses.
 

Systems Updates:

                     Eventually the TEKK data-radio's will be modified for 19.2Kbps
                       operation, and one 9600bps link will remain on the air for 9600bps
                       traffic.

                       Work is also progressing utilizing COTS hardware such as the
                    WAVELAN 900MHZ/2.4GHz 2Mbps Wireless ethernet cards. We
                       have four of these units and are in the process of reverse engineering
                       them in order to build a small amplifier in order to push the signal
                       through the harsh urban environment using a very narrow, focused
                       antenna system. Wavelan Post-mortem pictures in the lab.

                       10GHz 10Mbit/s Data link

                       The actual gunnplexors have been in operation for some time now. I
                       have transmitted voice/video over the links. The data interface is
                       under construction. 

                       A quick solution to get a system up and running might be to just attach
                       leased line T1 modems until an ethernet interface can be constructed. 

                       96K - 19.2k - 56k VHF/UHF
                       directional/omnidirectional equipment

                       The development in this area is progressing the furthest. Mostly due to
                       the availability to the equipment and antenna's, and with all the other
                       research currently underway at various Packet organizations and
                       commercial/educational institutions.
