The code is all available in svn at http://code.google.com/p/qrptracker/
or comprises standard libraries for things like Realtime clocks.
The most important parts are, first, the satellite tracking library, which is a port of James Miller's Plan13. http://code.google.com/p/qrptracker/source/browse/#svn/trunk/Arduino/libraries/Plan13
The library entitled TleStoreCallback facilitates the storage and retrieval of satellite three line elements in EEPROM, I2C ROM or what have you. (The callback approach means that the way in which the bytes are stored and retrieved can be determined at the time of the construction of the object.)
Finally, there's the FT817 library, which controls the FT817 radio. I hope to port this also to the Kenwood THD-7a handheld radio, so I will probably make a superclass for all radios.
The Sketches/satpack.pde file puts all this together in a loop that polls the 10 tles stored in the EEPROM for a visible satellite, tunes the radio appropriately and response to a button push by changing satellite modes and from satellite to satellite if more than one is up.
