[Elecraft] KPA1500 Tuner Question for the Group

The KAT500 utility will show the LC values in play after tuning (and 
caps on/not on the antenna side) .  I expect that the KPA1500 utility 
will do the same thing; I'll know more next week when I put the KPA1500 
online (the new station and shack are almost completed).

I keep the entire station, including the KPA500 and KAT500 utilities 
running 24/7/365; this allows simpler remote station operations.  Plus 
it's nice to compare the SWR on both devices (though neither has ever 
been different from the other); belt and suspenders.  I don't keep the 
amp(s) on all the time, just when I'm actively using the station.
