STABLE_HF_VFO


Posted on Feb 6, 2014

This circuit is a Hartley oscillator, as identified by the fact that the feedback to the JFET transistor (Q1) is supplied by a tap on the tuning inductance (L1). The position of the tap is usually between and 35 percent of the total coil length. A buffer amplifier is included, and it provides two basic functions: It boosts the low output power from the..
