you have a good point there, that needs some discussion indeed.

Actually I do support the participation of radio amateurs in this kind 
of scientific effort. I find it very interesting and I am willing to 
spend some time and even money on it.

However, I am frequently quite frustrated because these projects are 
often not well documented. So me and many others waste a lot of time 
just by finding out the signal parameters, modulation, how to decode, etc.
It is often difficult to find TLEs and up-to-date information about the 
project and the status of the satellite.

I think some of the project teams should pay more attention to provide 
as accurate as possible information and documentation to the amateur 
radio community. They have endless opportunities for that on the internet.
