Crystals ordered for 9MHz filter

        I ordered 40 9MHz crystals Monday - they should arrive
tomorrow. Will start matching them that night.
        Since these are all from the same supplier, there is a good
chance that my design will work pretty well straight out of the box,
without measuring it. If most of the xtals come out the same, it sure
would be nice.
        Should I do a SSB or CW filter? If CW, what bandwidth(s)
would be most useful? 400? 800? 1200? (getting near RTTY here...)
        What impedance should I make the filters? 50 ohm is what I
usually use, but that's a lousy match to a 1350 IF amp.
