Yes, the main AGC loop includes the DSP filters. But there is also a 
'hardware' AGC that kicks in on very strong (S9+30) signals that are 
within the crystal passband but outside of the DSP passband. This 
hardware AGC acts before the DSP (but usually does not act at all).

I believe the above to be essentially true but maybe a bit oversimplified.
