New 200 Hz K3 filter

[briancom]

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.

It's about the same as the 5-pole filter.

I just bought the new 200Hz filter and I really like it. I have no
issues with the gain setting; I have it set to 3 and it's running
fine.
