Thanks for the reply.
The setup is a K2 with a KAT2 tuner feeding a KPA-100/KAT-100 in a separate
enclosure. The connection is from Ant 1 of the K2 KAT2 to the BNC input of
the KAT-100. The internal wiring of the KPA-100/KAT-100 routes this to the
amplifier input in the usual way for this conglomeration("Remoting the
KPA100 into the EC2 enclosure", kk7p.com).
The KPA-100 is fully up-to-date as of Rev A-2 Nov 13, 2006. The upgrades
were made in March, 2012, and I remember that the bias setting went as
planned. Since I don't have a wattmeter, no adjustment of the wattmeter
balance or calibration was made with the upgrade. Since the upgrade
involved a lot of component changes, this could be the problem!
Would an incorrectly set KPA-100 power meter lead to the observed
differences in ALC response between low and high power settings?
Thanks,
Chris
