Mike,
You should have only 0.3 volts drop IN the K2 itself, so given your
display of 13.1 volts on the K2, that says you have a substantial
voltage drop in the power cable.
Is it wired directly to the power supply? Are all the connections
tight? Is the APP assembly at the K2 correct? Look at the end of the
connector - do you see only the contact blade? or can you see the end of
the spring finger under the contact blade visible? If the spring finger
is visible, the contact blades have not been pushed in far enough -
apply pressure to the back to seat the connector.
Make the same visual check on the APP connector mounted in the KPA100.
If it needs correction, you will have to get inside the KPA100 to
correct it.

The power supply is an MFJ 13.8V/25A switching power supply. It measures 13.63V
at the terminals.
The K2 shows 13.1V in receive mode.
During transmit on all bands, the K2 shows 11.3-11.9V, depending on the band.
All the power connections appear to be tight.
Thanks,
Mike NJ2OM
