– 9 –
(4) Alignment for FM IF and FM Tracking
Note:
1. Feed in a week signal from the Genescope.
Adjust T202 for max. gain and the waveform
of Fig. 1.
2. Connect AM signal generator to loop antenna,
bring near to ferrite antenna.
3. Input signal methode as follows.
4. Feed in a week signal to IC201 (Note 3) from the
genescope. Use the T201 core to from the S-
curve shown in the Fig. 2.
Adjust the symmetry of A and B about point C for
linearity.
5. SW1, SW2 dummy antenna is shown in Fig. 3.
6. FM dummy antenna is shown in Fig. 4.
R1=Rg=SG's output impedance (75
Ω
),
R2=75 - Rg/2
