Was there ever a response to the question:
Is there enough IF gain to compensate for the loss of this filter?

If one used spectrogram to try and set filter gains, there barely was 
enough gain with the old 200Hz filter to achieve same peak audio output 
within 1db of a carrier relative to the stock 2.7 KHz filter.

The new 200 Hz filter has more poles and presumably more loss.
