[Elecraft] K3 Load fails

[Paul Ferguson]

Dick,

Thanks. You were correct about the problem. I have a short (3 ft) extender 
cable connected to the KUSB cable. The junction between the two was slightly 
loose. I tightened it and loaded OK.

I suspected the K3 because the MCU load always worked. It must be that the FPF 
load exercised the data lines differently enough to show up the problem.  

Thanks to you and others for the help.
