I’m experiencing some strong interference across the 6 meter band which
I believe is coming from a local (within 40 miles) TV channel 2. Where
can I get a filter to deal with this? Is there a low pass filter with
a cutoff at 54 MHz? I only work SSB and CW on 6 so I’m only interested
in the lower portion of the band, if I cut off 52 MHz and above that
would be fine by me…..

Possibly you could notch it out. Look around for a ARRL handbook and check
out the subject.
Sometimes a hunk of coax with a trim cap can do the trick. Or you may have
to get more elaborate. Start out simple. Again look it up in a ARRL
handbook. I don't know about the new ones, since its all appliance ops now
a days.

There were commercial low pass filters on the market (Drake?) with a cut
off of
about 52MHz. Ratings were 1KW in the HF bands but only 100W on 6.
Worked well on 6 between the exciter and amp. I would suggest looking
for a surplus unit or building yourself as others have suggested.
