Getting back into weather satellite decoding after almost ten years. Plan is to have Raspberry Pi 4b display images decoded on a 7″ screen with Pi secured behind it. However first things first. Need to check I can decode the images on a PC.

Picture below is thermal imaging enhancement from NOAA 15 on a north pass pass at 18:42 local. Rig is a AOR DV-1 which has an ideal 30k filter but the recording output is only 15k discriminator! Antenna is a very low Diamond V2000 at around 2.5m so you can see the signal drop-outs (horizontal noise bands) from obstructions in the local environment. Software is the venerable wxtoimg pro edition. This is now effectively freeware though I paid for my pro edition back in the day. I couldn’t get the production copy from https://wxtoimgrestored.xyz/ to install under WIndows 10 but the beta version did and works fine.

Next up is to either get the V2000 higher or install the turnstile antenna I bought a year ago in a higher position. The ultimate is a quadrifilar antenna but that can wait until everything else is working. Software wise I’ll test a Airspy HF+ Discovery or SDRPlay SdxDx into wxtoimg via a virtual cable and also start building the software which is required on the Pi.
