[Elecraft] K3 VSWR Meter Calibration

[Don Wilhelm]

Ramon,

There is a calibration procedure in the manual to calibrate the 
wattmeter for forward power, but not for SWR.
I suggest you contact K3support for further assistance.

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?
