[Elecraft] K3S poor CW keying further investigation

[Don Schroder]

Bob,

Is it safe to run my K2 using Anderson Power Pole connections, and/or RigRunner equipment?

For my info, what is the reason for NOT using them?

I’m rewiring, and I want to do it right!

Nuts, just measure the drop between radio and power supply see if it is reasonable. Mine is 0.25 volts when transmitting.  I run 14.0 out of supply.
