http://sdr.osmocom.org/trac/wiki/rtl-sdr Just follow the links from here - there are literally hundreds of pages. Also, on Youtube there is/was a guy from Deutschland that had decoding software (for free) using RTL-SDR that you had to see to believe. You can get these RTL dongles on ebay for (literally) just a few dollars. I seem to remember the folks at DangerousPrototypes were doing a lot with these a couple of years ago.
