14 turns counter-clockwise on L127 made the rolling bars a lot higher, but I still cant get it to lock. I reverted L127 back to its original position. I need to hook up the frequency counter and see what the oscillator is running at.

I connected the frequency counter to the oscillator. It measured out at about 3.58MHz which was good. The target frequency is 3.57545 so I went off of that. The lowest I could get the oscillator by turning L127 (reactance coil) was 3.57970 which was plenty off. I think I need to add a cap in parallel with the 270 pf cap on the oscillator tank circuit. Your thoughts?
