As has been pointed out in the past, having your XIT turned on and off
frequency in the range of about - 250 hz to + 250 hz has to be a good thing for
the callers and the guy who just spotted himself by calling CQ.
+- 250 Hz is way too much, and will cause unnecessary QRM to users of
the next "channel" up or down from the run frequency.
+- 60 Hz is plenty. Listen to these for examples:
