Hi Fran, and welcome to the WeatherCat forum!
Fancy seeing you over here.
(Fran and I have been talking over on the WXForum, and I recommended he give WeatherCat a try.)
I pasted a link on the US satellite imagery for you over on the other forum. I don't use it, so I don't know if it meets your needs. Enter this link into Preferences --> Imagery --> Channel 1 URL and see if it is what you are looking for.
http://www.hpc.ncep.noaa.gov/sfc/satsfc.gifAs for your goals, WeatherCat (and I don't think any other Mac or PC software) send data
to NOAA. You can send to a lot of data collection agencies using the inbuilt tools or various templates, but NOAA gathers their own data, as far as I understand.
Let us know how we can make your start with WeatherCat easier. You'll find a very friendly and helpful bunch of people here, and Stu, the developer, is a regular contributor.

BTW, I see you are a Yehuda Moon fan! It was my morning's entertainment for several years until it was ended. I was "smorris" on the comments section, but I didn't post often. I've got all the books and swag to read whenever I need a Yehuda fix, though.
I ride a Bridgestone RB-T and an Xtracycle, along with the occasional go on a unicycle. I've recently been testing the waters about talking Mrs Avon-Weather into agreeing to my getting a Brompton, but I can't really justify it to myself, let alone her.
