I suggest the audible SWR indicator be in effect only while the TUNE
button is being pressed. But I'm not sure if such an indicator is even
feasible as I understand there is some "mission critical" code in the K3
that senses catastrophic antenna failure. An audible SWR indicator might
perhaps steal some cycles from that code, I don't know. But again I
suggest it only while TUNE is engaged so perhaps we could risk not
having protection against an antenna failure during these brief tuning
periods and touching up the SWR.
As to my station arrangement, it is precisely the reason why I use a
manual t-match on the other end of the desk: to keep my endfed wire and
its counterpoises, which would otherwise connect directly to the K3,
nearer to their egress point from the shack. So, the arrangement is by
intention.

But If I had to reach around to use an external matchbox and didn’t have a
visual indication of SWR while trying to do that, I think I’d rearrange my
station :-) Trying to tune a matchbox with nothing but a digital readout
(rather than an analog meter indication) is a hair-pulling PITA anyway.

I have also thought that an audible SWR indicator would be very useful but
never bothered to mention it as most would probably consider it to be a little
too gimmicky. But it would be quite handy for me when I'm using an external
match box-- when I lean across the desk to adjust it I can no longer easily see
the little SWR meter indicator in the K3 display.
I'd suggest a "geiger counter" type audible indicator: a fast beep for SWR
values greter than 3:1 and progressively slower as you zero in on 1:1.
