axeman2ooo said:the VC1 has strange readings, with 2.5VDC on one side, and 0.6VDC on the other checking with the multimeter on current flow
what would happen if I pull it and just bridge it open with a jumper? i know, the answer is prob a bad one, but if one side has required volts, then i cant help thinking it is faulty...
axeman2ooo said:okay not sure what you mean by reverse biased means
and i meant with the diode setting, not a voltage reading (DC or AC) it is the -->|-- setting
audioguru said:If the IC is doing anything, it is trying to reduce the frequency of the PLL oscillator by reducing the voltage to the varactor diode which increases its capacitance.
Try making a coil with one additional turn to increase its inductance to reduce the frequency of the PLL. Then the voltage at the test point should rise when the IC tries to increase the frequency.
