cool, exactly what i needed to know! i can trim mechanically if need be.

the lcd im using is similar to yours, but 16 x 2. sparksoftlcd.h

i was wondering about timing last night... i viewed the ppm on the scope and it looked kinda loose, or poorly defined. the i remembered that the the rbbb i was using on my solderless breadboard uses a ceramic resonator instead of a crystal. not sure if that would cause a sloppy ppm signal or not.... i'll try it with another board tonight to see if that tightens it up.
