Receiving weather satellites Raspberry PI or Linux PC

I found it necessary to create this article for a few reasons

Most of the YouTube/Instructables focus on aerials or only Windows installation. The ones that are for the Raspberry Pi are out of date. A url has changed which prevents WxToImg updating from Celestrak.com.

So this article is all done on a Raspberry Pi 4 4 Gb with 64 Bit Raspberry OS though it should work on 32 bit and Raspberry Pi 3 versions too with no mods though you may need to compile code from source.

As so much had changed, and I have never had successful reception of weather satellites. So I spent some time sorting out all the stages to do it and as a bonus and they no longer require building from source code.

Here is what you will need -
A budget SDR such as NooElec SmartSDR or RTL-SDR blog V3 or other clone
An aerial to receive 137 Mhz to start with
SDR Software such as GQRX or SDR++ (that does need to be compiled)
Specific settings on your SDR software for satellites
WxToImg to decode the downloaded audio files into images and overlay land and latitude/longitude grids and optionally colour the image in.
Satellite frequency and location tracking software GPredict, this will show when a satellite is approaching, control the SDR frequency and even auto-record multiple satellites.
