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!

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

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

WX Sonde Chasing
I happen to be in the bay area and so decided to take advantage of a sonde launch from the Oakland airport. The goal was to track and retrieve the sonde. I regularly receive and track these sondes from home, … Continue reading
Updated Station Layout
Here is the new console for USA-Satcom. This new layout gives quick access to all key equipment from one operating position. Things are still being updated but this is a good start.

Active Region 1520
I decided to take a look at AR1520 to see the source of the recent X Class Flare. Quite the view I must say, although I still have not seen any Aurora activity here in California.
Sonde Tracking Setup
I have been having fun tracking WX Sondes lately. Here is a screenshot of my setup. Telemetry is received from WX Sonde on L-Band and is decoded real time. The telemetry contains GPS information which is then used to automatically … Continue reading

RSI Vertex X-Band Downconverter
This is an X-Band Downconverter project using some surplus RSI Vertex equipment currently on the used market. The downconverter will be used to receive signals from 7250-7750 MHz and down convert them to L-Band 950-1450 MHz. More information is availableΓΒ here.
