[Elecraft] Filter problems

[Brian Alsop]

8 db.
This number was obtained by observing a signal generator carrier signal 
in Spectrogram (AGC off) with the 2.7 KHz filter.  Then each 
progressively narrow filter was kicked in and the gain adjusted for the 
same peak value.

The 200 Hz filter also needs 8db and perhaps a bit more.

The method leads to no loss in signal audio as the width control is 
progressively decreased.
