[Elecraft] K3S poor CW keying further investigation

[Chuck Chandler]

After more checking, I suspect the internal 100W amp is the common factor
in the poor keying characteristics I'm seeing and hearing about from my
rig.  I am trying to determine if my power supply is doing it's job.

I'm using a TenTec 963 switching supply rated at 25A continuous.  At rest
the K3S panel display shows 13.6V, with full power key down it dips to 11.5
or so.  This seems like a lot.  I'm running the power cable thru a
RigRunner Powerpole strip.  If I can dig out another power supply from the
packed boxes I can wire the K3S directly to the supply.

Is 11.5V at key down enough to cause the slow rise time being reported?
