Tony, All you need to do is go into the config menu, go to PWR SET and change it from "nor" to "Per bAnd". I have no idea what you are talking about with the LOCK function. The lock function I'm familiar with just locks the VFO A frequency. As to the input protection circuit on the KPA500, I'm sure it is pretty robust and knowing Elecraft I wouldn't worry about it failing. Of course you don't want to hit the KPA500 with 100 Watts. I would think you would want to develop some sort of operating procedure for your shack to make sure that doesn't happen.

All: Thanks for the advice regarding protection for the KPA500. I use more than one rig with my KPA500 so one has to pay attention to the drive levels. I suspect the protection circuit could fail if you accidentally pump 100 watts into the amp now and then. Regarding the K3S power-per-band setting: it looks like it requires the LOCK function to keep the power level one chooses. Is that the way it works or is there another option besides LOCK?
