Two pairs of stunning shots from $35 home satellite ground station (Raspberry Pi, TV rabbit ears antenna) this morning. From passes by NOAAs 18 and 19, east of Vancouver.

Atmospheric river conditions expected for Metro Vancouver later today.
Bands of rain coming ashore for northern Vancouver Island and the Central Coast overnight.

Yes, there are still parts of North America with wildfire activity and smoky skies. Here's the projection for Thursday morning, October 23.
Amazing to see this view from another world. Gale Crater on Mars. Image credit: NASA / JPL-Caltech.
Working on time sync for the Raspberry Pi.

Think this works.

sudo apt install systemd-timesyncd
sudo systemctl restart systemd-timesyncd

and test with this:

timedatectl

Not sure if this survives reboots.
Today's "blue marble" shot from GOES-18. As received and processed with my own @Nooelec-based ground station here in Vancouver, via 1.7 GHz radio signal. Near the satellite's solar noon, 2030 UTC / 1:30 PM PDT.
Taking aim at BC. Presently directed at the north central coast and Haida Gwaii, but drifting southward. Crop from 2030 UTC / 1:30 PM full disk shot taken by GOES-18. Received and processed with my own ground station in Vancouver.

Market brushes off threat of ChatGPT's ATLAS browser to Google/Alphabet.
METEOR MN2-4 at 3:30 PM this afternoon. Spot the stratovolcanoes Baker and Rainier. As received and processed from 137 MHz radio signal here in Vancouver.

Well, yes, there are 7 images, but other than the first, of grass, they are all of a patch of blue sky. At first I thought it wasn't switching, but that's because 6 of the 7 are of the same piece of sky.
Sure. It would be easier with a broader view but from this shot I'd say cumulo-nimbus.
Oh I have four SDRply units here (RSP1, RSP2, RSPdx, RSPduo). I already do that. This is about experimenting with a Pi and SDR. I can't get the SDRplay units running on the Pi, I don't think. I'm already running all sorts of FT8, WSPR, flight tracking, vessel tracking, geostationary sats etc.
Experimenting with amateur radio applications on a Raspberry Pi. Here running Gqrx with a Nooelec NESDR V5 and MLA-30+ loop antenna on 28.074 MHz for 10 m FT8 signals. Decoding in WSJT-X. Can't get V5 to tune below 25 MHz for other HF bands. Second shot shows 24 h mapping of the received signals.
A few overnight infrared beauties from weather satellite METEOR M N2-3. Received and processed with TV rabbit ears antenna, @Nooelec LNA and SDR, and a Raspberry Pi running Raspi NOAA V2-4.
