The frequency of oscillation is determined by the choice of inductors (bandswitch) and
the setting of the tuning capacitor. If the oscillator is tuned to 10.1 MHz, for example,
any radio signal on that frequency will be boosted and detected in the regeneration
process. The resulting output from transistor Q2 is a low-level audio signal which is
boosted to comfortable listening level by the LM386 integrated circuit amplifier.
The RF amplifier serves two purposes. It boosts the RF signals from the antenna to the
detector, and it minimizes the amount of oscillator RF going back out to the antenna.
Again, we hope you'll also look at the somewhat more technical explanation of how your
VEC-102K Receiver circuit works. If any terminology used in this book is unfamiliar to
you, please check the "Some Helpful Word & Abbreviations" section.
