An Adventure in Oscillator Theory

If you add enough "C" across the tuning coils to get the resonant frequency as low a 44 mhz, the tuning range will be greatly reduced.

Are there any cable channels in that range that are NTSC, anyway?

Fun project, but I seriously doubt that it will yield useful results.
