[Elecraft] Filter Crystals

[Brent Sutphin]

I have K2 # 2571.  I am one of those people who want my rig to work as =
well as possible.  I am having trouble with the decision whether or not =
to replace my filter crystals.  The filters are set up for a pass band =
of 1.5khz, 700hz, 400hz and 100hz.  Here is the symptom I would be =
trying to eliminate. I loose 10-12db of signal strength when I switch to =
the narrow 100hz filter.  Is this normal?  I set my filters using =
Spectrogram and the signal loss was measured with this software.  Any =
help would be appreciated.

Thanks
