I had an issue getting the TX gain calibration to pass at 52 MHz once,
but it was because SPLIT was enabled on 6 meters. For some reason my K3
will not transmit a carrier on 6 meters by holding the TUNE button if
SPLIT is enabled. It will on every band but 6.

I just installed the KXV3B board, upgrading from the KXV3A. When I went to
do the 1mW calibration at the end, the calibration failed because the SWR
was 2.9:1 on 52 MHz. I tried a couple more times, with different dummy
loads and cables and found the same result.
I then connected an external SWR meter to the dummy load and found that
the external SWR meter showed a flat 1:1 SWR with the dummy load (as
expected) but the K3 SWR value was always higher, typically 1.4 or 1.5:1 up
to 2.9:1 on 52 MHz into the dummy load. The tuner works perfectly on all
bands, however.
Has anyone had a similar issue? I can’t quite tell if the problem is in
the KAT3 or on the K3 main board, and more importantly what the fix might
be. Also, since the 1mW calibration failed, are there any other
workarounds? Many thanks in advance!
