Interesting. This is the type I've decided to build as the basis for
my next sweep generator attempt, since it's claimed the config is more
amenable to being pulled than most others (although I won't be
attempting to pull it anything like as much as my first abortive
attempt using a Cmos-based inverter). Do you find it's a reliable and
stable design, Jim? I assume if it wasn't you wouldn't still be using
it!


Why not use a VCO built from an LC oscillator? Its really easy to build one
with a single transistor that sweeps your band.


Major problem with that idea is the fact that Paul has no way to
calibrate or adjust the VCO. That's why he wants to start with a crystal
oscillator. If it works, he won't have to calibrate it.
