If you would like information about the K9NG 9600 baud modem,
I would suggest you contact TAPR (Tuscon Amateur Packet Radio) at:

Tuscon Amateur Packet Radio Club
P.O. Box 22888
Tuscon, Arizona  87534

They should be able to tell you all you would like to know about
Steve Goode's 9600 baud packet TNC.

One other place to look for information on the modem is in the
Gateway newsletter - Volume 2, Issue 2, September 4, 1985.  There
is an article around page 6 entitled, "K9NG MODEM PROJECT".

The PC-board is supposed to be designed to connect a TNC and a
Hamtronics FM-5 220 MHz transceiver.  Other transceivers can be
substituted, with appropriate modifications to the modem board.

This will not be a step-by-step project for the beginning kitbuilder,
but the documentation provided with the board and the article that
Steve submitted to the proceedings of the fourth ARRL Amateur Radio
Computer Networking conference (available for $10 from the ARRL)
should allow experienced builders to assemble and test the modem.

Hope that was helpful!
