[Elecraft] OT: The Colpitts mystery

[Fred Jensen]

Probably not Bill since it has drifted way off original topic and 
continues to do so.  I posed the original question.  My guess is that 
the Colpitts oscillator was probably the easiest to get stable [or 
nearly so] of the extant designs then because it uses capacitive 
feedback.  It would be the most familiar to examinees and the FCC just 
settled on it.  I remember that some only had to draw the schematic, 
others [including me] had to complete a partial schematic and answer 
questions.

Incidentally, Colpitts was also on my 1P and 2T exams.  Since the only 
copier then was Thermofax, once they had a question set about it, they 
probably just stuck to it.
