Alan,
The PIC may be contributing to the noise. Makes sure that there is
adequate bypassing at the PIC. You might try soldering a .1 ufd
capacitor *directly* across the PIC's power supply and ground pins.

Note that I mean that the capacitor is soldered directly to the
pins, NOT to the traces.

A 10 ufd tantulum capacitor in parallel with the .1 ufd may also
help in particularly stubborn cases. If even that doesn't work,
leave the caps in place, and cut the trace going to Vss. Now take a
small ferrite bead or toroid and loop a piece of wire wrap wire
or magnet wire* through the hole a couple of turns (the more the
better). Now wire the two ends of this wire across the cut in the
trace. This will normally kill most high frequency noise due
to the PIC.

*I prefer wire wrap wire, because magnet wire can be
a real pain to strip.
