In ELECTOR electronic project 1.2 GHz frequency meter dec.92, there is used 40 pf variable capacitor connected to pin 19 of the processor. ......But this all doesn't address the effect of thermal variations on the variable cap and on the crystal. If it was that easy, we wouldn't need ovened crystals in really high precision clock systems. Steve |
