LRIT and HRIT are relatively easy to receive and decode. They are both vertical polarity (linear). Last month I built a simple feed for my dish using a Quaker Oats container wrapped in aluminum sheeting. It worked great and I got lots of images.
Compiling the Open Satellite code for Windows was a bit challenging, but I got it working. If you don't want to compile it, there are Windows binaries on Github in the release directory.
Currently I am building a septum feed for receiving GRB. This will also require a DVB-S2 receiver that can deal with a generic stream . Many of the TBS cards can record a generic stream using TBS Recorder, but the TBS IP tool (which we need) cannot do generic streams.
Anyway, receiving images and data from the GOES satellites is an interesting hobby!
