[Elecraft] Fault Anomalie with Flex 6700, KPA500, KAT500

[Ken]

If I understand your situation, you are depending on the rf signal 
triggering the change in frequency and tuning.  That usually works but 
is slower than having the tuning set before you push the transmit button.

Using something like DxLab Commander lets a signal be sent to the tuner 
(or amplifier) as soon as you change the VFO and therefore the amp and 
tuner can be ready as soon as the transmit switch is thrown.

Likewise the Flex friendly utility DDUTIL will communicate with the 
KPA500 as well as DXCommander.
