There is a local FM station @ 94.9 Mhz that bleeds over the adjacent
channel @ 94.7 (non-local) which I would like to receive.  I've positioned
the antenna for optimum reception, but lately the interference has
worsened.  I would like to build a tunable notch or low-pass filter
to put at the antenna terminals of the rx'er.  Which type of filter would
be the best design?  How many filter stages would be best?  Any 
schematics available?
