I imagine it wouldn't be too tricky to turn the clock source on an off at=
 the=20
CW rate rather than FM modulate the carrier ?  This would be more useful
when hunting with a non-FM ARDF receiver.  Not sure how you go into the
off state, and whether the clock source needs to be re-programmed to go o=
n=20
again.
