Alexander: 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? 73, Dean Straw, N6BV GA for all K3 users. So many guys has talks about perfect audio sound of K3. So many talks about "analog K3 sound" on e-ham. But how it possible if K3 have the so bad in-band IMD?
