This interface project will allow you to operate the analog birds with a single non full duplex, all-mode VHF/UHF transceiver. While the circuit and the software are designed for the popular Yaesu FT-817 transceiver and satellite tracking software package, SatPC32, it serves as an example that can be adapted to other radios and tracking software--left only to the imagination of the builder.
For more information please see Mark Spencer's, WA8SME, "Satellite CAT Interface for Working the Analog Birds" on page 40-43 of October QST.
The interface was created as part of resource development for the ARRL Education & Technology Program. AMSAT receives a donation from the sale of each kit.
