Dear friends, We know that some Satellite Operators use diferent system to doppler control.
For Linear Transponder 1) Adjust uplink and downlink automatic by CAT? (Not always woks, some times I´m up or down from the computer adjust) 2) Adjust uplink and downlink manual 3) Keep Uplink fixed and adjust only the Downlink frequency. What is the more indicate method to use? FT-847 have knob to adjust Uplink without change downlink VFO, and I´m using it to keep my voice in downlink at same downlink much I can. But I know some operators use fixed uplink. How you do? -- 73 Fabiano Moser CR7/PY5RX ARISS-PORTUGAL (Amateur Radio on the International Space Station) Representative at Teleconference and Portugal Telebridge Coordinator.
