Actually, they're not duplex, they're SPLIT, like working a DX station on HF where you transmit UP from the DX station's frequency. The uplink and downlink frequencies for the ISS are different, and because they are in the same band, require a special version of SatPC32 (SatPC32ISS) to control the two frequencies.

OK,
You are saying that no 2 meter contacts are simplex. contacts are DUPLEX on 2 meters with ISS.
Where do you find the ISS section on SATPC32? We found ISS listed but it was 435? and 145.800.
Is PSK and Slow Scan TV random transmissions from ISS or is there a schedule so we know what classes in school can use them or may be there is a schedule, posted some where.
We want to start these programs the first of the year in school.
Maybe there is a knowledgeable and active AMSAT person in the Chesapeake, VA - Hampton Roads area. Does any one know?
God Bless
