Here is the transceiver part of the RF link. Here <http://home.attbi.com/~xxmegamixmanxx/xm1202-E915_v2b_schematic_E017V07 A.pdf> I'm planning on using a different micro because the Atmega8L is too big expensive and uses too much power. IF anyone else makes a schematic and/or PCB please email me the files.
