Frequencies are nominal values from the SatNOGS database (service: amateur) and satellites change them or go silent without notice. For linear transponders the Doppler value is for the middle of the passband. Always check the operator’s or AMSAT status before a pass.

New to satellites?

You can work FM satellites with a dual-band handheld and a small directional antenna. Read how to work amateur radio satellites, then use the pass predictor to pick a good pass (above 20° of maximum elevation is a good start).

Positions are computed from public orbital elements (CelesTrak / US Space Force 18th SDS) with the SGP4 model and are accurate to a few kilometres; amateur radio data from the SatNOGS DB (CC BY-SA).
