Awesome work! https://t.co/Ln9cOGM0okr00t @r2x0t
THIS. IS. JUST. AWESOME. !!!
This is video decoded from the 8455MHz high rate downlink @uhf_satcom received yesterday. All the work on the decoder and data analysis really paid off in the end!
Video shows solar panel of Chang'e-5 glistening in the sun and dust floating around. https://t.co/FKc92kgskl

Last night's Chang'e 5.
@coastal8049 list:
Orbiter-B - 8463.7MHz (decoded)
Orbiter-A - 8571.2Mhz (detected)
Lander - 8455MHz (no signal)
AZ and EL offsets needed to correct SpaceTrack elements. As much as +7 deg AZ and -1.5 deg. EL. Offsets were changes before and after TCA. https://t.co/5CKAXPxevV

More X-band wonders coming out of the lab today. A VE4MA choke ring made out Aluminum to reduce system weight. Next is the depolarizer and transition. Goal ultra light dish and feed for telescope mounting. https://t.co/1POcDAXFHe

This is the high speed data downlink, 2.5MSym/s BPSK, CCSDS framed, but not using APIDs. Uses some custom protocol on VChan 38. It was very busy earlier, now it's mostly idling with some basic telemetry.
This looks like 8 channels of accelerometer data, some changes are visible: https://t.co/3LigSvKfqs https://t.co/0frT5rixkk

Chang'e 5 Downlink on X-Band centred on 8455MHz, a lump of fast wide band data! https://t.co/Eye0cMFFCf

Feed center check with laser bore sight in custom self-centering printed adapter plate!
Seems there is room for improvement.
WIll install some turnbuckle threaded rods to allow adjustment per feed leg. https://t.co/2N0hnpRgrh
