Show Every Twist of Dial Produces Odd Squeal If the receiving set employs regenerative regen-erative action the operator should give care to the manner in which the filament fila-ment current Is regulated on the detector de-tector tube. A regenerative set sometimes acts as a miniature transmitting station, and a great deal of troublesome and needless Interference can be created In a neighborhood by this type of receiver. re-ceiver. The howling that Is heard In a receiving set Is generally due to the users of regenerative sets tuning dials In an effort to bring In distant stations. Much of this interference can be eliminated If the operator keeps his filament at a low temperature. By observing this rule not only will the life of the tubes be prolonged, but receiving conditions will be made much better for neighbors who may be trying to tune In at the same time. The amount of energy that can be radiated from a regenerative receiver receiv-er Is directly proportional to the brilliancy bril-liancy of the filament or the detector tube. A good idea is to twist the dials as Utile as possible, since every twist produces a peculiar squeal in the sets of nearby listeners. |
