[Elecraft] K3 Notch

[gary bartlett]

...and while they are at it (Wayne told me it was on the list), do something
to make it easier for us CW contester ops to use Notch.  I wish, when one
first turned on Notch, that the default frequency turned up anywhere except
at the very extreme upper end of its range where, unfortunately, it is of no
value to me.  By the time I dial the notch from 2000HZ to down to where I
need it, it's too late when things are moving quickly.  I have found that
there are contesting occasions in which use of the Notch into a wide filter
is a better solution than very narrowed filters.

When in CW Mode it should default to somewhere closer to where a person
needs it -- i.e., inside the limits of whatever filter is in play.  Or why
not default to the rig's selected side-tone pitch?  That way an op would
know exactly where to go with the Notch control when first turned on.  Even
if the *Notch Go-to-2000HZ* command were turned OFF inside the radio and the
Notch left where last used would be better.  Anything.

I believe that I can show that the K3 Notch was better when the rig was
first new, before an early firmware update came along and broke it by moving
the CW Notch default up to 2Khz.  This is the first radio that I've owned in
which I have used the Notch and found Lyle's work so satisfying that I've
worked that control into the way I operate (when I think of it).   I bet
it's wasted on a lot CW ops because it is slow and awkward to employ.

Here's an ergonomic issue:  I sometimes wonder if the Notch switch could be
changed such that it goes into the Manual Adjust mode with a PUSH of the
Notch button, rather than requiring a HOLD because, for whatever reason, my
first attempt at using the Notch button invariably is usually wrong, and
besides my way is faster.

I use the notch frequently. I am curious as to why it appears so difficult
to
bring it inside the AGC loop. Perhaps the auto notch is problematic, but the
manual notch is just another filter box just like the main brick wall
filter. This is pretty high on my wish list as I use the notch filter often
when the inevitable tunerupper appears on top of a DX's frequency.
