[Elecraft] Bewildering K3/KPA500 power cycling.

[Wes Stewart]

Yes, I'm using SVGA extension cables ($2.80 @Cable Wholesale) that are straight 
through. The male) ends have the the unneeded/unused pins broken out.  I had 
missed removing a pin 8.  It's gone now and all is well.

This, of course will wreak havoc with the AUX IO system since it requires all pins to be separate. It also means that some things will be connected improperly on the KPA500 (or the K3) which will give very unpleasant surprises.
