Used the following:

• RX at aprox 145.933 MHz USB BW 3.2 kHz
• 2 * 6 el Yagi circular polarization (Vårgårda)
• AlfaSpid RAS az/el rotor
• LNA Mini-2 from SHF Elektronik
• LMR-400 coax
• SDR Airspy HF+ Discovery
• 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 FUNcube-1 Dashboard. Set to 96 kHz and 16 bit.
• Telemetry software: FUNcube-1 Dashboard.

Strong telemetry at 145.858 MHz easy to decode. Used the following:

• 2 * 6 el Yagi circular polarization (Vårgårda)
• AlfaSpid RAS az/el rotor
• LNA Mini-2 from SHF Elektronik

• VB-Cable: virtual audio cable for piping audio from SDR Console to Soundmodem. Set to 96 kHz and 16 bit.
• Soundmodem v 1.05 at mode BPSK AX.25 1200bd (1k2). Be sure that the BPSK signal is centered ”over” the signal in the spectrum. See image.
• Telemetry reader and forwarder from DK3WN, in order to see and forward telemetry to SatNOGS. Note that this is a beta version.

AO-73 Funcube-1 at 40mW telemetry but very easy to hear.

Test your UHF antennas with the LO-19 LUSAT constant carrier on 437.125 MHz.

Bugsat-1 RX with fixed 15 el X-Yagi (H) at 10 degree elevation, RTL-SDR v3 to RPi SatNOGS station.

RX with 13 el LFA X-yagi and horizontal polarisation. A strong ”bird” at 437.500 MHz. Use WFM and the special 9k6 1KUNS-PF Soundmodem decoder.
