aircraft communication receiver

The simplest V_HF receiver is the su perregenera tlve. Unfortunately, it is also one of the most difficult to get working properly ... Most of the problems stem from the fact that the oscillator is self-quenching. The receiver described here is less critical than the conventional super- regen, but it also uses more components: the various superregen functions are each performed in separate stages. The first stage (T 1 ) is an RF pre am pli- fier. The input (aerial) is not tuned, both in the interest of a simple alignment procedure and to reduce the danger of feedback from the oscillator to the RF input.
