1921 Radio Rev. May 248 The production of notes by a high-frequency oscillating valve making use of a grid leak and condenser, and the factors governing the pitch of this note, were discussed. The application of this arrangement (termed by Major Prince a ‘squegger’) to a receiver..was also described.
1932 Admiralty Handbk. Wireless Telegr. 1931 xvi. 727 Receivers in which..self~oscillations alternately build up and are damped out without the necessity of a separate circuit to vary the reaction. These are called self-quenching receivers or squeggers.
1932 A. W. Ladner & C. R. Stoner Short Wave Wireless Communication viii. 147 The presence of audible modulation..may also be brought about by a high resistance in the grid circuit... This effect..was called originally a ‘squegger’.
1932 Wireless Engineer IX. 186 In the super~regenerative class, two receivers were available, one of the self-quench (or squegger) type.
1946 C. A. Quarrington Mod. Pract. Radio & Television II. x. 156 Time bases employing the squegger principle are inclined to be affected unduly by working conditions.
