Hi Wayne and thanks for the info re KPA500 power supply
The toroid transformer in the KPA 500 takes up most of the space available
in the K3-sized cabinet and it is amazing that the developers managed to add
a linear regulator and even a 500W amp etc. – hi!
Now toroids are a bit hard on the

That is entirely normal. Which one of the 3 methods mentioned are you
using to calibrate the 4 MHz reference?
1) Measure the TP3 frequency with an accurate external counter - adjust
C22 until the K2 display matches the external counter.
2) Listen to the 4 MHz signal with another

How?
Try going to China as an individual company and pursuing a cease and
desist suit. Or collect infringement damages. If a government is not
watching your six, it won't happen. One reason to manufacture in
China is to have control of the clones that are going to be made one
way or another.

A new feature would then be to reset the old KAT3 settings or to 'calibrate'
the whole band automatically with the KAT3. And after that it is a little
step to a complete antenna analyzer feature on the K3 hi!
