This is a short list of interesting and useful pages for anyone interested in amateur radio astronomy... not the best set of links but some stuff I found sat in my home directory with the tag "post this when you get a moment".
Have you ever heard the Sun? An introduction to radio astronomy of the Sun. Also the Metsähovi Radio Observatory does regular solar monitoring - they have some really nice images. More on the different types of burst can be found on The Radio Sun.
How to build and test a receiver and observe Jupiter - Radio JOVE. The Radio JOVE project is a really nice way of getting into radio astronomy. They also have a really nice discussion of the Jovian Decametric radio emission.
There is also the UK Amateur Radio Astronomy network and BAA radio group. Oh and don't forget the Society of Amateur Radio Astronomers.
The NRAO have an excellent page on some methods for putting together kit todo radio astronomy. The also have a page that is dedicated to the Procedure for Making the Itty Bitty Radio Telescope.
