President Jackson Unlocked Clarifier Mod. Surprisingly there are still Jacksons in use with the fine clarifier unmodified. From the factory the fine clarifier only changes the receive frequency while the coarse control changes both transmit and receive. With this scheme it's almost impossible to find center slot. The solution is to unlock the transmitter so the fine changes both transmit and receive. The following is a simple, effective way to unlock and increase the range of the clarifier: 1. Completely remove D58. 2. Follow the Brown wire from the Fine Clarifier Control and remove it from the Switch PC Board and connect it to constant +8 volts. 3. Follow the Blue wire from the Coarse Clarifier Control and remove it from the Switch PC Board and connect it to ground. 4. Realign on frequency with both controls in 12 O'clock position. 5. With a frequency counter connected to TP3 (R73) adjust the following: L14 Controls AM/FM = 15.5100 MHz L15 Controls USB = 15.5125 MHz L16 Controls LSB = 15.5075 MHz ©CBWI
