[Elecraft] K3 Beta firmware rev. 2.80: misc. improvements (AM mode, DVR, etc.)

[Brett Howard]

I just tried shutting down the DVR TX by tapping my keyer and that
doesn't seem to work...  Tapping the key transmits when in SSB mode so
it seems to reason that I would be able to interrupt DVR TX using that
method.  Granted most of the time I'll probably interrupt via VOX but it
seems like the paddles should do it too.  I tried this (using the
paddles both in PTT and VOX modes).

As I type this I got a few short little blips of VOX activation as my
mic picked up my keyboard.  I do have the noise gate enabled (although
I'm not sure if the noise gate actually affects the VOX pickup) but
still yet I get small blips.  It would be a really slick improvement
(although if it worked right no one would notice it) if short blips in
VOX pickup did not interrupt DVR TX instead if it took a slightly longer
bit it would prevent some embarrasing falses.  Just a thought.

Thank you kindly gentlemen.
