       Cobra 142 GTL  Install EXPO 100 "B" Kit
       1. Replace 11.1125 crystal with a 11.3258 crystal.
       2. Isolate the ground pin 10 of the MB8719 PLL by cutting the PC
       trace.
       3. At this point, turn your radio on and check to varify that
       all channels are locked in and working. If it is not, adjust
       these in the following order:
       a. CT3 for USB.
       b. L20 for LSB.
       c. L19 for AM.
       4. Install a SPST switch between pins 11 and 12 of the MB8719
       PLL
       5. Install a SPST switch across the cut you made to isolate pin
       10.
       6. Check all connections for shorts.
       7. Check to make sure everything is working before you drill
       holes for the switches!
