The DCI brand of interdigital bandpass filters are neat for cleaning up
reception by blocking out of band Intermod sources etc.  But they are too
board for any effect on in band signals.

Has anyone re-tuned the cavities to all the same frequency to see how well
the filter performs as a narrowband filter?
