[Elecraft] k3 firmware update.

[Bruce McLaughlin]

I understand that would be very difficult to do.  The auto notch looks for
an unmodulated carrier to attack and so it leaves amplitude modulated SSB
signals alone.  But a CW signal is really a carrier modulated by duration
but not by amplitude and so the auto notch would have a hard time knowing to
leave the CW signal alone - - in other words it probably would think it is a
carrier and do its thing and then poof - - - there goes the QSO. With the
narrow bandwidth useable for CW I've rarely been troubled by adjacent
carriers - - they are just not in the pass band.  And if a carrier does
appear right on the CW station's frequency I don't think much could be done
about that anyway.  But a manual notch allows you to carefully sneak up on
the offending signal in a much more careful way and if the carrier is
slightly off the CW signal sometimes you can do the job that way.  Sometimes
the human brain works better than the best automated system I think.

Thanks! I did not realize that. Maybe is it possible in the future to have 
it also in cw, a TAP to lock a carrier and then put the value in MANUAL.
