I have been a lurker on the reflector for almost a year and this is my
first email to request guidance.

I have a KX3 and a KXPA100 and with the recent thread about running a
calibration I figured I needed to do likewise. The amp is a new addition to
my setup so I am still learning the details. Anyway, while running the KX3
Utility I get a failure during the calibration process (the output is
below). The amp is in bypass mode and I am using an MFJ-260C for the dummy
load attached to ANT1.

Is the failure only on 29.000Mhz or does the whole process fail if any of
the calibrations fail? Anyway to continue?

Also, could the temperature of the dummy load impact the test, that is if I
run the test back to back several times, as the dummy load heats up will
this impact the process (I am thinking yes)? Should I cool the dummy load
before testing?

Thank you in advance.
