     Peaking the alignment towards the bottom of the bands really should
do the trick.  Just set your VFO lower when doing the alignment.  The
other thing you might consider is doing the capacitor mod designed to
flatten the filters on four band boards with the older, more temperature
sensitive capacitors.  Also note that your alignment can change as the
components "break in".  Re-aligning the filters really isn't a big deal.
