Hi, while the satellite is approaching the radios uplink frequency has to be LOWER than the satellites RX frequency to arrive - enhanced by the Doppler effect - on that frequency. The SatPC32 frequency window doesn't show the Doppler shift but the correction values, which have to have always opposite signs for downlink and uplink.
