Discription
Internal Equivalent Circuit
34
MPX-PLL input
LPF formed with internal resistance 30k
Ω and
pin 34 eternal capacity
↓
HPF formed by subtracting the above LPS passage
signal from the Composite signal.

Supply to MPX-PLL circuit
35
HCC capacitor pin
With pin 35 external capacity,
High-Cut frequency characteristics are set.
The value of internal resistance R35 is changed
over in AM/FM mode:
FM mode: R35=30k
Ω
AM mode: R35=100k
Ω
36
37
Noise detection
sensitivity
AGC adj pin
With the noise sensitivity setting pin of pin 36, set
the medium electric field (about 50dB
μ). Then, with
the AGC-Adj pin of pin 37, carry out setting in the
weak field (20 to 30dB
μ).

AM/FM S-meter (DC)
AM/FM S-meter (AC)
Current drive type S-meter output
Pin 38:
Eliminate the AC component by external capacity
Pin 40:
Leaves the AC component
(Pin for NC noise extraction and for multipath noise
extraction)
