@LEDSAT_Team telemetry over Stockholm 2023-07-02. Good copy, nice S/N, but strong local interference. Software and hardware used:

• RX at aprox 435.188 MHz USB
• 2 x 13 el LFA X-Yagi (InnovAntenna) switched between HOR and VER polarisation
• AlfaSpid RAS az/el rotor
• LNA Mini-70 from SHF Elektronik
• LMR-400 coax
• Airspy Mini SDR
• 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.
• Greencube Soundmodem v0.08b at mode 1200bd
• GetKISS+ v 1.4.2 from DK3WN for sending telemetry to SatNOGS dB

CubeBel-2 telemetry @EU1SAT over Stockholm ar 2023-07-02. Software and hardware used:

• RX at aprox 436.991 MHz Wide FM BW 12 kHz
• 2 x 13 el LFA X-Yagi (InnovAntenna) switched between HOR and VER polarisation
• AlfaSpid RAS az/el rotor
• LNA Mini-70 from SHF Elektronik
• LMR-400 coax
• Airspy Mini SDR
• 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.
• HS-Soundmodem v0.27 at mode FSK G3RUH 9600bd.
• GetKISS+ v 1.4.2 from DK3WN for sending telemetry to SatNOGS dB

This time a did a simultaneously RX with tracking Yagi with RCHP polarisation and my SatNOGS station with a disconne antenna.

The SatNOGS station with the disconne performance very good with 80 frames received. Compared with my station with RHCP Yagis, Airspy Mini, SDR-Console v3, Nayif-1 software = 103 frames received.
