The dummy load needs to be connected to the XVTR OUT jack, not the main
antenna connector. The tuner path has nothing to do with it.
See K3 manual around page 53 or so.

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!
