[Elecraft] SWR protection

[Don Wilhelm]

Hein,

You could do that by sending commands via the KIO2 interface to the K2 - but
you would have to implement a microprocessor in your amplifier to accomplish
that feat.  See the KIO2 Programmers Reference document.

The KPA100 accomplishes similar function, but communicates to the base K2
via the AUXBUS signals - problem is that the AUXBUS signalling is Elecraft
proprietary information, so using that is problematic.

There is no one signal that can be used to control the K2 power.  I would
think it easier to provide a switch in your amplifier to shunt the input
power off to a dummy load or insert an attenuator - that way all the
controls reside in the amplifier itself.
