same problem for me. I can't even run power on 160m into a dummy load with the amp/tuner on bypass, but if they are in line it works fine.

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.
