I agree with Dave. Disconnect the coax from the MFJ ATU. Terminate the line with a 50-ohm load. Look at the input end with your MFJ analyzer and the K3's SWR meter. If all checks out, then reactivate the ATU and place the 50-ohm load at the output of the MFJ ATU and invoke the autotune function. In both cases, SWR should read reasonably close to 1:1, and Z measured on the MFJ analyzer (if it reads more than just SWR), should be close to 50 ohms. Probably stating the obvious, but also check to ensure that the unit is really being powered by +12V to +15V and that regulation is good (low voltage drop) during the tune sequence.
