INTERNAL CIRCUIT AND FUNCTIONAL DESCRIPTION
1. AM OSCILLATION CIRCUIT (Fig.1) Q
For adopting the level control (ALC) circuit, ' . Q6
the oscillation level is stabilized. 3
The' oscillation frequency can be made up to about ALC
30MHz and can be applied to Sil band. The relation mas Q2
of the oscillation voltage and the oscillation 105
current to Q of the oscillation coil ls shown In
Graph I.
2. AM LOW-CUT CIRCUIT (Fig.2)'
This circuit can improve the clearness of the
AM audio by decreasing the low-frequency content 800 vosc, IOSC - Q
of the output signal during AM reception.
The cut-off frequency fr, is determined by the "2 600
internal resistance 22kn(Typ.) and the external 3 400
capacitor C5 of©pin as following; 3 Vosc

TERMINAL FOR MPX VCO STOP
By using (g)pin, VCO.of MPX IC can be stopped.
The output circuit ls shown in Fig.3, and the
connections to MPX ICs (TA737OP/F and
TA7343AP/AF) are shown in Fig.4.
CONNECTION TO MPX IC
In case of connecting biPX IC secondarily
to this IC to make the stereo function,
it is conventionally necessary to switch
the capacitor C9 with AM/FM in IF output.
However, since the output Impedance of
TA7787AP/AF and TA8110AP/AF are changed
over to 10kn in AM and 500n in FM,
the frequency characteristics of
AM/FM can easily be changed with a
piece of the external capacitor C9 as
shown in Fig.5.
The frequency characteristics in this
state are shown in Fig.6.
