@uvsqsat telemetry 9k6 BPSK – strong signal.

I have used the following hardware and software:

• RX at aprox 437.019 MHz Wide-USB
• 26 el UHF LFA X-Yagi (2* 13 el) from InnovAntennas.
• AlfaSpid RAS az/el rotor
• LNA Mini-70 from SHF Elektronik
• LMR-400 coax
• Airspy Mini
• SDR-Console v3 with doppler correction of downlink and satellite tracking, rotor control
• PstRotator for rotor control interface between SDR-Console and RAS controller
• VB-Cable: virtual audio cable for piping audio from SDR Console to Soundmodem. Set to 96 kHz and 16 bit.
• Soundmodem G3RUH BPSK9600 v 0.04b at mode BPSK G3RUH 9600bd. Be sure that the BPSK signal is centered ”over” the signal in the spectrum.
• UVSQsat Decoder v0.6. Data is beeing sent to both SatNOGS network database and MVP Telemetry server.

• PstRotator for rotor control interface between SDR-Console and RAS controller
• VB-Cable: virtual audio cable for piping audio from SDR Console to Soundmodem. Set to 96 kHz and 16 bit.
• HS-Soundmodem 1KUNS-PF v0.09b at mode 9600bd
• GetKISS+ v 1.3.11 from DK3WN – data uploaded to SatNOGS.
• Kepler from SatNOGS 49069
