I would *except* that it is not built(or designed) yet.  It will use a 33
MHz crystal on a 16f873 with a tone-to-voltage convertor.  The AFSK
output will be a signal eminating from one of the pics outputs(a
transister will provide the NEGATIVE keying).  If I read the tone
convertor with an a/d input I will be able to tell whether it is 1200 Hz
tone or 2200 Hz tone.  Just requires another EEPROM to store data(24C65).
 Those packet headers can be large.
