I addressed something similar years ago.  See my comments in:

Just wondering if anyone else sees significant differences in SWR readings on the K3, the KPA500, and the KAT500?  
I get a fairly low reading on a 40 delta loop I made on an MFJ Analyzer.  However, the K3 reads a 2.1 with the tuner and amp in bypass/standby modes, tuner reads 1.2, and amp reads a 1.4.   With amp placed into operate and tuner left in bypass the K3 reads 1.5, the amp 1.4, and tuner reads 1.2.   I suspect this means the amps input needs to be tuned somehow.    I know, just use the tuner and all is well but I'd like to know why this is occurring.
