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.
