I want to use the switched filters at the output of a 1KW solid
state amp to prevent harmonics from escaping to the antenna.

I have 40 & 20M B&W low pass filters and a ParaDynamics 10M so
far.  I have been seeing filters for 160, 80 and 15m when I came
upon the AMECO text and it got me to thinking.

Even and odd harmonics directly related to 15M would appear to
be addressed by certain 10M low pass filters, so a 15M-specific
filter would appear to be unnecessary.  True?
