No. The new DSP AGC changes are completely independent of the hardware  
AGC time constant.

Increasing the size of C238 was experimental (maybe even "dodgy", in  
hindsight, to use the vernacular). It may help with much stronger  
signals (S9+20 or so is where hardware AGC really kicks in). But I  
think we've now demonstrated that in-band IMD in dense S3-S5 pile-ups  
can be reduced with DSP AGC changes.
