Amen and Amen.  The above statement I can fully agree with.  The 400 Hz
filters have an excellent shape factor...better than Kenwood's own.  The
only down side is installation.  On my TS850 the instructions were to solder
the units into place and that left me  scared spitless to do that in a new
rig.  Well, all went well...  If I ever upgrade and they are available....I
will put these filters in.
