John,
For the OP1 filter, drop the high frequency marker to 2600 Hz and center
between the 2 markers.
Remember that what is important is for the low frequency corner (-3 dB
point) of the passband be placed quite near 300 Hz. That is also
important for the more narrow SSB filters as well.
Dohn,

Use the instructions on Tom Hammond's website www.n0ss.net or the links on
the Elecraft site and they will match.
I hope you did not pay for that version 14.1 yet - it is much more than you
need for setting the K2 filters.
Of course if you
2 matches
