I have an older NanoVNA (V1?) and it

Bill,
The MFJ analyzers are not that accurate. I own a MFJ-259B and results will vary with battery voltage!
There is a calibration procedure for them and I suspect some leave the MFJ facility without proper calibration. I know that sounds unbelievable because MFJ is known for their rigorous quality control but it was the case on my unit.
