Please look at the shape of that filter.
As I understood, it will always be one peak. Not really suitable for
SSB I think.
Good luck,
Chris.

Hi Arv,
Thanks for your message. I planned some experiments with the
filters and
the SpectrumAnalyzer when I finished the BITX20. The filter of
JF1OZL was
new for me. I will try that too.

FYI
I noticed that JF1OZL uses resistors instead of capacitors in his
crystal ladder filters.
See: <> for his diagrams.
This might be interesting for those of you that are having
problems
getting the filter
response that you want.
