[Elecraft] Suggested enhancements for K3

[Drew AF2Z]

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 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.
