This causes the negative pulses at U22(1) to voltage (U23 pin 6) is a negative relationship. That is, the arrive a little earlier than before, arriving ahead of the lower the tuning voltage, the higher the frequency.

(Higher loop bandwidth is allowable at higher input 9E-4-31. The A2 board amplifies the Channel A signal and frequencies.) This greatly reduces acquisition time for a 10 then divides it by four before sending it to A1 via J2(9).
