1.2m dish, 1dB NF LNA, modified Ku feed. Using an Airspy R2 with HDSDR, 9GHz LO.
HDSDR plot shows it hunting then locking to Earth station (probably)

1.2m dish, 1dB NF LNA, modified Ku feed. Using an Airspy R2 with HDSDR, 9GHz LO.
HDSDR plot shows it hunting then locking to Earth station (probably)
Stronger today with more sidebands visible (37Hz BW, 9GHz LO, 580MHz line is spurious)
Now at 1.4e6km it's a fair bit weaker and some sidebands are no longer visible to me. I shifted the LO to 8936MHz to avoid 20MHz spurii from the Airspy RX.
Now on the High Gain Antenna (HGA) and very strong at about 2 million km
Now 2.6 million km, on HGA, PSK modulation visible again. 8936MHz LO.
Now 2.95 million km, on HGA. 8936MHz LO.
Now 3.95 million km, on HGA. 8936MHz LO.
2nd plot has averaging set to 128 to show PSK more clearly.
Now 21.7 million km, on HGA. 8936MHz LO.
Now 30.6 million km. 9000MHz LO, with and without averaging.
45.3 million km. 9000MHz LO, waterfall plot has spectrum inverted, 1.2m dish.
24.5 million km. 9000MHz LO
Coming back to do a fly-by of Earth
10.2 million km. After Earth fly-by
RX Tuned to 8420.340MHz, IF frequency 21.4MHz with frequency inversion. Upper plot not inverted.
