REGENERATION CONTROL

REGENERATION CONTROL

In valve receiving circuits employing regeneration, some means is generally provided for controlling this action. If the circuit is adjusted to a point where its action is too great, telephone signals will be distorted by oscillations set up in the detector valve itself. When this happens, it is merely necessary to alter the position of the regeneration control. Regeneration, when properly employed, has the effect of amplifying incoming signals many times and the best results may be obtained by bringing the regenerator control up to a point just before oscillation starts, or by bringing it to an oscillating point and then reducing it slightly. The point of oscillation may be recognised by a peculiar continuous mushy sound in the‘telephone receivers and a sharp click may be heard when oscillation starts or stops. Too great a degree of regeneration also has the effect of producing whistling noises. The regenerative feature in receiving sets when properly employed is of great value, but improperly employed it is not conducive to the best operation.
