"Hot switching RF in an external ATU is not to be recommended for
any radio at any level."
BUT - you DO hot-switch your K3's RF output when using any relay-based
auto-tuner, including the internal K3 auto-tuner. So my reasoning is that
I'd rather hot-switch the 100-watt PA at 15 watts rather than the 10-watt PA
at 5 watts. And then, my MFJ-998 (which I use with my ALS-600) reads SWR
more accurately at 15 watts than it does at 5 watts, so when I go to full
power the tuned SWR is still minimum. As Wayne stated earlier, SWR readings
at low power may be less accurate due to the detector diode voltage drop at
low power.
