I have modified the 10 m bp filter for higher bandwidth by just adding a
single capacitor in this way (mentioned a little while ago on this
reflector under the heading of EU mod):

"The only other filter I have changed is the 10/12 m filter, but that
has nothing to do with EU. It is just because I find it a bit narrow if
you want to use most of the 10 m band for e.g. satellite operation.
After a lot of experimentation I have come up with a very simple mod to
this filter. The mod is based on the K2 serial # 3000+ filter that you
have. I want it unchanged on 12 m and wider on 10 m. The mod is to add a
1.5-2.2 pF capacitor across terminals 4 and 7 of relay K6. This
increases the coupling on 10 meters. The capacitor is shorted for 12 m
operation. This is an idea which has been taken from the DL7MAJ mods.
The filter has to be tuned by going back and forth between the bands as
the settings influence each other. This is in contrast to the pre-mod
filter."
