Notes and circuits
“The regenerative circuit (or regen) allows an electronic signal to be amplified many times by the same active device”
From Wikipedia: http://en.wikipedia.org/wiki/Regenerative_circuit
In other words it uses feedback.

“… the design virtually eliminates the negative aspects of regenerative receivers such as antenna radiation, frequency pulling, micro- phonics and hand capacitance effects.” Ironically these are the features I am looking for.
