Where I keep up with amateur satellites: what I have worked, where to listen, which frequencies they use, which ones are alive and when new launches happen.

Listen and receive
QO-100 (Es’hail-2) is geostationary: no passes, the dish stays fixed. The BATC WebSDR, hosted at Goonhilly, lets you hear the transponder in the browser without any equipment.
- QO-100 WebSDR (banda estreita) — listen to the narrowband transponder in the browser (CW, SSB)
- QO-100 Spectrum Viewer (banda larga) — spectrum of the DATV transponder
- QO-100 Dish Pointing — calculator and map for pointing the dish
- SatNOGS Network — observations made by stations worldwide, with waterfalls
- BATC Es'hail-2 wiki — how the Goonhilly ground station works
Satellite status
Amateur satellites fail, go silent or only work in sunlight; it is worth checking the status before trying a contact.
- AMSAT Status — amateur satellite status, reported by operators
- Live Linear Satellites — AMSAT table of active linear satellites, with frequencies
- FUNcube Data Warehouse — FUNcube satellites telemetry
- SatNOGS DB — database of satellites and transmitters, with received data
- ARISS — upcoming school contacts with the ISS

On low-Earth-orbit satellites there is Doppler shift: the receive frequency moves by about ±10 kHz on UHF during a pass, so you need to correct it over time. Inverting linear transponders swap the sideband between uplink and downlink.
