PK232SAT.2 Earlier PK-232's connected the middle pins of JP4,5,6 to the inner pins with a circuit trace on the bottom of the PC board. These three traces must be cut. Check beneath the JP pins to see if your model has these traces. Current models use three removable jumpers that will not be needed with the switches. The above information is based on my own experimentation and several conversations with the helpful technical staff at Advanced Electronics Applications (AEA). The Uosat 11 hardware mod was published by AMSAT-UK in their monthly OSCAR NEWS #73, October 1988. A list of programs for determining satellite passes can be obtained from PROJECT OSCAR, P.O. Box 1136, Los Altos, Ca. 94023-1136 and from AMSAT, P.O. Box 27, Washington D.C. 20044. Everyone interested in satellite activities is invited to check into the Tuesday night East Coast, Central and Pacific Coast AMSAT nets on 3840 Khz (+/- QRM) at 8 PM local time. Two meter AMSAT nets also are active in some areas. Contact AMSAT or Project Oscar for more information on these nets and for other satellite related information.
