Satdump, STEREO-A & Pictures of the Sun

  • STEREO-A, was the first thing I found on 8.4GHz. It is approaching earth and is now quite close at about 11.5Mkm and will it get closer. It's signal is now strong enough to decode on 8.4GHz on a small dish For the full story see here: STEREO-A Comes Home

    Here are a some of animated GIFs from yesterday. I used a 1.2m dish, 1dB NF LNA, downconverter, Airspy R2 on a Pi400 running SDR++ server and Satdump on a linux box. The SNR was around 8dB except during downpours when it dropped to 5dB. The pictures are from the UV instruments and the corona camera. It can be better to download them and play locally, they should loop.

    Satdump is amazing software and well worth exploring if you are into more unusual satellite stuff. Thanks to everyone involved.
