6.5 MHz input / RF AGC
delay adj.
6.5 MHz 2nd SIF input.
And this terminal has RF AGC delay
point adjustment function.
100 A current is outputted from this
terminal. Connect a resister (5.6 k )
and a volume (10 k ) between GND
in series.

6.0 MHz input / AFT defeat
5.5 MHz input /
system SW1
4.5 MHz input /
system SW2
These terminals are input of 6.0 MHz
2nd SIF, 5.5 MHz 2nd SIF and 4.5
MHz 2nd SIF.
No.14 terminal has AFT defeat
function. If resister is connected
between this terminal and GND, AFT
defeat is active.
No.15 and No.16 terminals have
system switch function. The table of
'Condition of No.15 terminal and No.16
terminal' vs 'System' is on next page
17
AF output
Gain of the audio amplifier is selected
0 dB or 6 dB by system switches. This
system absorbs difference of the SIF's
deviations (25 kHz or 50 kHz at 100%
modulation).
Output resistance of this terminal is
selected 5 k or 7.5 k by system
switches. So connect a capacitor
between GND, the time-constant of the
deemphasis is changed by system
switches.

19
VCO tank
Connect tank for VCO between these
terminals.
