I have been trying to simulate a VCO for a CB radio on LTspice, but cannot get it to run. The ac analysis give me a peak at about 3.5 MHz but cannot get anything from the .trans. It is supposed to oscillate at 17.55 MHz. and is basically a LC circuit connected to Pins 1 and 2 of the chip TA7310P which are the base Pin1 and emitter Pin2 of an input transistor used as an oscillator. C5 on the spice circuit is meant to be a Varactor diode. V2 would normally be the dc control voltage. Would be grateful on any help on how to simulate this Please.
