A lot of the need for a tuner here would vanish if the KPA500 could
handle a 2.5:1 SWR. Phone->CW band excursions could be tolerated
without exceeding that limit. I've looked at the voltages and currents
involved. At 500 watts, they don't intractable.
I wonder if the incremental cost would be around the price a KAT500?
Call it a KPA500+.

mechanism to turn off the "improvement".
In cases where you are not using a KPA500 and a retune requires a couple of
transmissions, why abandon an acceptable ATU setting if you move a bit down the
band unless poor SWR is actually encountered?
