[Elecraft] KAt100 power on question

[Don Wilhelm]

The KAT100 needs both the 12 volt power connection *and* the 12CTRL 
signal from the K2 to power itself on.
So yes, you need the control cable plugged from the base K2 (or KPA100) 
to the KAT100 before you will see any lights.  The control cable is 
shown in the KAT100 manual.
