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 ??

What is a swinging choke

The Ameritron ALS-600 solid state amplifier uses a swinging choke in
its 50 volt 20 amp power supply. The choke is essentially the
regulating element because it swings in and out of core saturation. I
understand they now have a SMPS that they will offer with the ALS-600.
Maybe they should have some questions about SMPS on the exam.
