Varactor diode specifications can be slippery.

My idiot light just came on. You said 11.325 MHz crystal. This radio is built with a 11.1125 crystal. I have made this substitution to add upper channels, but it leaves me wondering how much the crystal is contributing to this mystery. If you unsolder one end of C132 does this get you any closer? This was a strategy to counteract the side effect of putting a RF choke in the circuit to stretch the clarifier's range suggested in the EXPO 100 channel kit instructions. Might be worth seeing how it affects this radio.
