[Elecraft] K3 VSWR Meter Calibration

[Nr4c]

I don't think the "bypass" in the KAT3 is a true bypass. It sets a "solution" which should be equivalent to a bypass. 

The new KAT3a has a true "bypass" relay.

An external VSWR meter indicates 1:1 while the K3 most of the time indicates readings varying up to 2:1 at times. I am using the same short coax stub to connect the instruments one at a time to eliminate other possibilities. Is there a way to “calibrate” the VSWR indicator in the K3? My K3 is serial number 4416. The Auto Tuner in it works fine and reduces the indication to 1:1 as it is supposed to but when bypassing it the VSWR indication will always be off. Any suggestions?
