Jim,
>From your description, the inverter you described is almost correct BUT it
won't work because there is no voltage available to it.
The output from the KPA100 is a HEXFET open 'collector' - which means it
makes a path to ground when active (transmit state) and is open during
receive. The Am
It would be possible to do this switching with the K2 Amplifier Keying
Circuit in Elecraft application notes and adding a PNP transistor and a
resistor
to provide the correct switching. This could be installed external to the K2
possibly at the TenTec Hercules amplifier keying input.

I picked up a used TenTec Hercules amp in very good condition. It works fine
from my
Omni A and Omni V, but I'm thinking that I would also like to drive it with my
K2. I've
looked at the drive from the Omni A, and it appears that 10-15 watts will get
me within a
dB or so of rated power from t
