Complete guide for satellite communication — step-by-step workflow, tools, checklist, and expert tips to get started.
Identify FM or linear satellite passes with elevation above your horizon mask.
Estimate uplink/downlink frequency correction during pass approach and departure.
Model path loss to LEO satellite including antenna gain and polarization loss.
Execute pass with rotator or manual tracking while adjusting for Doppler.
Document grid squares, equipment, and signal reports for future passes.
Model uplink/downlink margin for LEO satellite passes.
Calculate path loss to satellite at slant range.
Convert pass frequencies for Doppler correction steps.
Compare arrow yagi vs omnidirectional satellite antennas.
Interpret signal strength changes during pass.
Starting points for FM satellite operation.
| Satellite | Uplink (MHz) | Downlink (MHz) |
|---|---|---|
| SO-50 | 145.850 FM | 436.795 FM |
| ISS | 145.990 FM | 437.800 FM |
| Linear (RS-44) | SSB/CW | SSB/CW |
Hearing your own downlink while transmitting makes timing and tuning easier.
FM satellites teach Doppler and tracking without SSB transceiver complexity.
Excessive uplink power desenses transponder for all users — use bare foot power.
