No filter.  Just either a Kenwood TS480 or an SDR setup with a $20 
dongle for a receiver.  I still have no idea where the TV stations 
are that I hear on channel 2a and 2c.  I used to hear one on 2b but 
it is gone and all I hear there now is a steady carrier from local 
cable leakage.

On 55.239 I get a fairly strong residual carrier with strong airplane 
tracks.  On 55.259 I get a faint carrier (sometimes nearly 
undetectable) and fainter airplane tracks, but decent meteor returns.

My antenna is a 6 meter ham halo (horizontal polarization) at about 
16 feet AGL.
