[Elecraft] [K3] GPIO input to switch output power with external amplifier on?

[Eric Swartz WA6HHQ - Elecraft]

Hi Thomas,

I'll discuss this with Wayne to see if it is possible.

We're pretty busy in engineering right now, so even if it is possible, it may be a while before it happens.

This is a critical proprietary timing component of internal K3 operation and improper use will cause serious problems for the K3, including possible damage of internal components during disturbed T/R timing. Its is not a simple serial interface.
