[Elecraft] KPA500-KAT500 tuning settings

[Bob Wilson, N6TV]

Though it works, best practice when using a K3 is to use AUX cables.  The
AUXBUS line (pin 2) in the AUX cable provides notification to the K3 as the
amp switches from standby to operate, so drive power can be adjusted
automatically  AUXBUS also lets you use the band buttons on the KPA500 to
change bands on the K3, which most folks find much more convenient than
cycling through the band up/down buttons on the radio.
