[Elecraft] Request for NR and NTCH inside AGC loop

[W7TEA]

I've found that adjusting AGC THR makes quite a difference.  I normally have
THR at 4 but when I need the NR, I adjust THR to 6 or even 7.  I set NR at
2-1 or 2-2.  With this setting, I normally do not have to turn AF gain up.

I am not the first one writing that NTCH is outside the AGC loop and that NR
reduces the signal strength. With NR, less on strong signals but much on
weak signals. For example, signals that are buried in noise seem to be
brought to life with NR 3-3 but the AF gain needs to be all the way up, or
more.
