    The micro ssb market may be getting cheaper.

    Colt 357A PLL Problem C5121

    From my expirience with C5121 there were two causes of stuck at channel 9. Bad chip or not working crystal resonator. (Check capacitors at the crystal) VCO out of lock still allowed to change channels.

    It is CMOS pll. Fragile to static etc... If crystal is OK, then PLL is dead. Mike
