[Elecraft] K3: Latest Beta FW - Vox, TX Gate and Notch

[W7BRS Jeff Wandling]

In reference to (email below), the observations are also noticed here.

First, thanks Lyle for looking at it.  Let us know if we're hearing things?

I had run 3.97 since I purchased the K3 (2nd K3), and was reluctant to
upgrade Firmware.  Fear of nightmare SS QRM made me decide to feast on the
new DSP to see if I could survive the maelstrom.  Wrong.   The audio gaps
are there as described below.  Further, it occurs also when adjusting WIDTH
even when on the same xtal.  I noticed it on 4.22, and 4.19.  I'm back to
3.97.   I prefer releases that are outta-beta; I believe that K3s are
shipped with the latest release that's gold-disc worthy.  I haven't figured
out if the release numbers mean anything or not.  Or how to tell a blood
dripping leading edge release vs. a version that has been regressed against
the backlog in Gnats.

I've used K3's for a long time (2 years), so unless something fundamental
has changed there is definitely a unique change to the code that creates a
silent audio (did I just write that) gap when making certain adjustments:
WIDTH on the same xtal (not the gap you hear when you flip from FL1 to FL2
when adjusting WIDTH).  Or activating NOTCH, etc..

Gary at Elecraft did a fine job trying to help.  No worries Gary.

But I think there's something to look at here.  This isn't expected
behavior.

And, while we're talking about NOTCH --

How many of you would like this:   Whatever your NOTCH setting is, it is
preserved on power cycle similar to the way NB, NR, AGC, etc.. are preserved
on power cycle.

73 and DX,

Lyle is looking into this.     73, Guy.
