0-18MHz Receiver/July-Aug 2009/Varicap Oscillator

The radio-active topic

Can't get this to oscillate. It won't oscillate in the LTSpice simulation either. Has anyone got this to work successfully?
LTspice file attached. I set both pots to mid position, DC voltages check with simulation.
VE3PKC

Ok...now I see that this is only the tuning circuit...the actual oscillator is in the NE612...I have been staring at this too long. No oscillation on pins6/7 of the NE612...will probe further.
