[Elecraft] K2 Push To Talk

One option for the K2/transverter hot switching problem on CW is to build a sequencer which breaks the TX IF line, like this one:

This only works, however, if you are running very low IF power from the K60XV (or at least run the 10W TX IF through an attenuator so the K2 PA sees a decent match at all times).
