Greg;
If the coil was backwards, would it even oscillate? The frequency that ir is oscillating at (4.4 MHz) is way higher than it should be. The fact that the tuning capacitor does not change the frequency almost seem as if it is not connected. Without the tuning capacitor it could possibly oscillate that high? I disconnected the tuning cap and checked with ind. meter, and it does show change. Will have to recheck circuitry.
