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.
