8-1. The S-meter DC input voltage is set by the variable resistor R1 connected to pin 32. While it is often said that a
curve such as that shown in figure 59 is ideal for separation control when multipath interference occurs, if the
pin 32 voltage is too high, separation control in strong field reception, as shown in figure 60, will become
impossible. Thus it is desirable to adjust the circuit so that the pin 32 voltage remains under 2 V when
saturated.
8-2. The time constant with which the MRC circuit controls the separation is determined by an internal 100
resistor and C2 during charge and by a constant current of 7 A and C2 during discharge.
