Hi Bill,

It all depends upon the range of loudness range you want your ears to 
tolerate.

I did some plots (SLOPE=12) for THR =10, 12, 13.   I used the K3 S meter 
high resolution readout, the K3 dBV readout and a variable output signal 
generator.   The RF gain calibration and Smeter calibration were done 
first using an XG2.

With a THR of 13, I get about a 40db change from the min detectable 
signal and S9+50db. The AGC kicks in at about S6-7 with these settings.

Lower values of THR give lower S meter values of AGC activation and less 
audio range.

The starting values were really obtained by what sounded good.   The 
data collection was done after.
So ears work as a way to set these parameters.
