AUDIO_CONTROL_FOR_ANTENNA_PHASER

Rectified audio in multiple-antenna aircraft receiver alternately charges C2 and C3 at grids of V2. Bistable mvbr V3 performs switching in synchronism with pulse generator so each switch position corresponds to change in antenna phasing. When peak of signal is passed and phase is reversed, V4 pulls in K1 and sends control signal to control unit. K2 opens when difference in potentials of C2 and C3 becomes excessive, forcing system to resume cycling until output is again maximized.-I.
