The Internet is a fantastic resource for radio amateurs. Without it, it would be much harder to get information on different aspects of the hobby. But the amount of outdated information that has never been either removed or updated can result in a lot of time wasted.
I have been trying to find out about amateur FM satellites currently operation. My searches turned up several pages about the South African satellite Sunsat, one of which states that it "recently commenced operation." Another article on how to work your first satellite gives a detailed description of how to work Sunsat, despite the fact that it apparently ceased operation some time in 2001!
A search for the current ARISS operational schedule found pages listing a schedule for 2001, and another for 2005!
Is it too much to ask for people who post information on the web to take it down again when it is no longer valid, if it cannot be updated?
