Secure with the 3 mounting screws. STEP 4 Jumper pin 9 to pin 8, pin 9 to pin 1 on J2506. J2506 is the test socket. It is located on the left front of the radio. It protrudes through a rectangular hole in the microprocessor board.
Some radios have a slightly different crystal frequency.
The dip switch settings may vary from the one that I have listed above. STEP 6 Completely re-align the radio, follow manufacturers procedure. Look at the VCO output using a spectrum analyzer for this adjustment. The new range to be set up for the PLL is 35.1874 to 33.5993 Mhz. This may help those without a spectrum analyzer.
