Just out of curousity -- what modern Ham gear uses a Colpitts oscillator or
a swinging choke ??

Then why ask these questions on a 2005 Ham test ??

Maybe ask about a VCO or a crowbar circuit ??



All of them!!! The reference oscillator in every phase locked loop is
generally a Colpitt's oscillator. I suspect that every oscillator in
the VCO circuit is also Colpitt's.

By simply asking the question you make the point!!!

The required level of knowledge for a license today is significantly
poorer than 40 or 50 years ago.
