[Elecraft] K2 Outboard Amplifier options

[Don Wilhelm]

Curt,

The KIO2 is not actually a requirement, but it does provide the K2 to 
KPA100 signals necessary.
There are substitutes for the KIO2 for those who would like to make the 
appropriate connections inside their K2 between the Control Board P4 and 
a connector to the outside of the base K2.  The signals that need to be 
piped out are:
AUXBUS
Ground
12 CTRL
VRFDET
8R

The signals above are needed in the KPA100 no matter where it is mounted.

73,
Don W3FPR
