Ron's comments about re-design of the output circuit are spot on. The minuscule gain in output power simply isn't worth the likely stress and/or harm to the K2. You say it's used for emergency communications in the field. IMHO this is -not- the place to abuse the radio.
The same thing seems to be going on in relation to the KX3's output power and the efforts to come up with heat sinks for the PA. I'm reminded of a local who's infamous for "blowing up" his rigs. He simply can't accept the fact that there -are- design limitations. Another reason to never purchase a used radio. (;-) 73!
