operating state of Q5, the anode of CR4 is at either
CR5, CR6, coupling capacitors C21., C22, and load
resistors R18, R19. Approximately 3 vdc is impressed
approximately + 14 volts (Q5 cut off) or below 1.0 volt
(Q5 saturated). When this voltage is high, the diodes
on the cathode of CR6 from a voltage divider consisting
are forward biased, and the signal from .3 appears
of R12 and R13 (L8 is an rf choke). Depending on the
