[Elecraft] K3S poor CW keying further investigation

[Bob McGraw K4TAX]

As to the RigRunner power pole strip.........PUT IT IN THE TRASH where 
it belongs.    NEVER NEVER NEVER use a power distribution strip to power 
a 100 watt radio.   ALWAYS connect the radio direct to the power supply 
terminals.   NO exceptions!
