BTW Rick, I looked at the schematic a little closer last night and L2 is a rf transformer, not the oscillator coil like I previously said. You're on the right track. The 16" antenna is bypassing the rf amplifier and feeding the signal to the mixer/oscillator. Have you tried a different 12AU6? Check out C6 at 100pf. The signal is not getting from the rf amplifier to the oscillator. Yes, don't tweak any FM trimmers, you could loose your signal altogether.
