Strong GMSK 4k8 UHF telemetry. Data uploaded to #satnogs , software and hardware used:

• RX at aprox 435.650 MHz Wide FM BW 10 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 4800bd.
• GetKISS+ v 1.4.2 from DK3WN

CAS-10 has been deployed and is active with strong telemetry. Unfortunately the satellite will never go over 2 degree elevation at my QTH (JO89WK).

Still going strong!

BLUEWALKER-3 telemetry over Sollentuna/Stockholm. Very strong at 437.500 MHz but only one decode with SoundModem. It could/should be more.

Several of the SWSU satellites spotted/heard over Stockholm. Strong downlinks, antenna (13 el Yagi) fixed position Az: 147 El: 7
