Nicely done. I like the dual varactor arrangement, which should have
a lot of advantages over a single diode. All in all, simple and

If I'm reading correctly, the "varactor" is a pair of plain old
rectifier diodes! I never would have thought of using power diodes for
this application. I guess I thought there would have been way too much
capacitance to be able to reasonably resonate them at 100 MHz. Good stuff!
