low output only on 40m

a run through all the bands with a dummy load - my uBITX is now outputting about 2 watts on 40m - when it is strong on all the other bands.  sounds like the LPF is out of tune - anyone seen this before?  (no I haven't finished my PHSNA yet -- but maybe I can manually check it with my DDS somehow)
