I had actually thought about a crystal latice filter  I think I can
find three 10MHz crystals and put them in series.     The trouble is
I'm not sure what problem the filter might introduce and I don't have
a way to measure the filter's performance

I'm thinking of adding an RF amplifier using just one 2n5109 and an LC filter.
