Don - there is a 100kHz BCD line on the display board which feeds the 100kHz digit display and the upper loop board's programmable divider N2. Is the 100kHz offset at every 100k step, if not it might be worth looking at the '1' BCD around ML2 and ML41 on the display board and the wiring to the upper loop board?
