I must look in to this as I have the necessary radio equipment. I first encountered Wx satellite reception at a talk by Verulam Amateur Radio Club. The speaker showed home built equipment that had a revolving drum holding photographic paper that used a modulated high power light source to create the images. I still have a frame store I built in the mid 80's from a design published by the Remote Imaging Group. Output was to a TV set using modulated UHF either live or from audio recording. I used a 2m converter initially tuned on a Kenwood R1000 to the 22MHz band. I then built a dedicated 137MHx crystal controlled direct conversion Rx, again I think an RIG published design. It was a real thrill receiving images live.
I really need to adopt new technologies but there's some merit in the old hardware based solutions.[emoticon:4191f5ee34e248a29fa0dbe8d975f74a]

Very interesting.

I need to dig out my SDR dongle to try some of these.

Another very useful post. A friend captures images from the weather satellites in the UK too, and while he had told me the process and I knew it at a high-level, it wasn't written down so I had nothing to follow.

By the way you mention WB-FM at 35-38 MHz, is that a typo? As I understand, the RTL dongles can only manage 2 MHz or so of bandwidth. I guess you mean 35-38 kHz?
