WSPR beacon with Arduino

today i published the code for an beacon controller based on the popular arduino board. The code calculates the whole WSPR message and generates the 2 minute sine tone sequence. The software is synconized with an DCF77 timecode receiver. The tone sequence can drive the mic input of an transceiver or like i use it , output an control voltage for the vxo of an simple 30m beacon transmitter.
