[amsat-bb] swtiching frequency in satpc32

Hi to all! maybe someone can help me, i can´t find in google the answer.

If i put the SatPC32 software to tracking the ISS, where i need to select to switch for example for de ISS, to conmute from the APRS freq to the FM repeater, and tracking that in my equipment?

Thanks!
