KX3 - calibration SWR 99.9-1 is too high for calibration

[VE3NFK]

Hello

Just finished updating firmware; using latest utility pgm; radio works fine
 - 'tune' into dummy load gives 1.1-1.

 Calibration from utility instantly fails at 1.900 99.9-1 SWR.  

Can't think of anything to try - commercial dummy load directly connected.

Thanks  72  John VE3NFK

John,

Try to run the TX Gain Calibration manually.  See the KX3 manual page 33.
That will tell you whether it fails on only some bands, but not others.  
The Utility program quits after the 1st error.
If the manual calibration succeeds, then you might want to try the
Utility process again, but it is not necessary.

John,

Another thing - you could have a bad coax between the KX3 and the dummy
load - overlook nothing, especially simple things like that which are
often forgotten.  Make no assumptions about the 'goodness' of cables and
any adapters.  Substitute a known good cable, or disconnect it from the
KX3 and measure that end with an antenna analyzer.
