[Elecraft] K3 transmitter gain calibration fails due high SWR

[peterc281]

I decided to run through the calibration of my K3 after it came back from the
VK9NT Dxpo. I find I can’t complete the transmit gain calibration as the SWR
is to high on some bands.
1.8 to 10.1 are fine, the rest are as follows 14.1 is 1.5:1, 18.1 1.8:1,
21.1 2.7:1, 24.9 2.2:1, 28.4 2.4:1, 50.1 1.3:1.
I’m after suggestions what to look for as I am not sure what could cause
this problem.
