My contribution to the Sprite project is now hosted at : http://kicksat.wordpress.com/support/kicksat-ground-station/
although I still need to amend the typo that sets the frequency at 437.4 when it should be 437.240. Thanks to MJ for setting this up for me now that my personal website hosted by Google is full (I need to talk to them about that!). In the page I have tried to set out a simple and modest station (my own!) which should be in the reach of a target school science teacher or similar. This station received the 100mW transmitter of $50sat at a distance of 640km as shown on the waterfall display. Thanks to the team of $50sat for their inspirational project. This waterfall display and SDR receiver is needed for the bandwidth of the Sprite transmisison, and the aim is to record the entire pass for the project's database. From an operator's point of view, the most important thing to notice is that no dongle is accurately calibrated and so you should not necessarily believe that the frequency you set in software is the frequency you actually get! I hope this page will encourage people to try for the interception of the Sprirtes when they are launched shortly. 73 de andy g0SFJ
