And if you want to record your TX and RX audio it is very possible to
overdrive the sound card because the Line Out level is controlled by the AF
Gain control!

Subject: Re: [Elecraft] K3: in-band-IMD etc. what does this mean to a user?
Once I started a thread on eham on Mark V Field having high AF distortion;
the second harmonic of a 400Hz carrier was only about 30 db below. After
many exchanges it turned out that I was overdriving the sound card; after
reducing the input the second harmonic was about 45 db below, not bad.
45 db is what they are finding. Not bad.
