I seem to have successfully added a Jason mode to the AD9850/51 DDS Module. 
 It certainly works from compur to computer anyway !   The DDS module is 
put into Jaso mode by grounding PB2.  Then it receives the native Jason 
command words in the range 0 - 16 (decimal) at 9600 Baud and sets the DDS 
frequency appropriately.  The centre frequency used is that stored in teh 
EEPROM from the normal programming.  The Frequency increment (actually 8 
times the increment) also has to be saved in EE prior to Jason operation. 
 The S/W dpes not operate as a beacon transmitter in its own right, just as 
the interface between the PC and frequency source.

I may put out a low power  test transmission sometime this weekend at an RF 
power level in the -40dBW ERP region if anyone is interested, and other 
tasks don't intervene.
