REFERENCE
CP INPUT
Reference frequency input from this pin. The reference frequency
is 3.58MHz, inserting 270k
between this pin to GND.
The reference frequency is 4.0MHz, this pin leaving open.

AFT OUTPUT
AFT output. AFT center voltage is generated by an external
bleeder. The AFT gain is increased by increasing the resistance
of this external bleeder resister. However, this resister must not
exceed 390
.
This circuit includes a control function that control the AFT voltage
to naturally approach the center voltage during weak field
reception.
