Post MFJ 948 ATU calibration
Is there any way to calibrate the SWR meter on the MFJ 948 manual ATU
I’m aware that there is a tolerance on all meters, however on tuner bypass my MFJ unit is reading my SWR about 20-30% higher than the inbuilt SWR meter and two other external SWR meters on both my antennas and on a dummy load.
Many thanks
