The Audio mod is a very simply! You just need to add simple two resistor pararell on KIO3 module and replace one RFI choke! If anyone need mode just send me mail and I will forward pdf direct !

Sorry but I don't read Russian. What were the K3's AGC settings for the IMD measurements? At a large input signal (S9+50 dB), using a "Fast" AGC time constant will often result in poor IMD for conventional receivers using analog type of AGC systems. I don't know the details of the K3's AGC system, however.
Have you tried the S9+50 dB input signal with the "Slow" AGC setting?
