Connection and Set Up
INPUT: AM ANTENNA TERMINAL
For OSC: Input 150kHz(400Hz, 30% modulation), 501uV/m(54dBuV/m)
to the Loop Antenna of a Unit.
For Tracking: Input 210kHz(400Hz, 30% modulation), 501uv/m(54dBuV/m) to the Loop
Antenna of a Unit.
Connection and Set Up
OUTPUIT: JP203(-) and JP204(+) for Frequency Range adjustment.
See Fig.1 and Fig.4
on page XX
Adjustment Point
1. LW OSC of RF215 (Black core) for Frequency Range.
2. LW ANT. Coil of RF215 (Red core) for Tracking.
Adjustment Method
1. Frequency Range
Set the tuning frequency of UNIT to 150kHz.
Adjust RF215 (Orange core) so that leading of DC VOLT METER reads 2.3
Adjust RF215 (Orange core) so that leading of DC VOLT METER reads 2.3
±
0.1V
2. Tracking
Set the tuning frequency of UNIT to 210kHz.
Adjust RF215 (Red core) so that output level reads maximum.

Adjustment Method
1. Discriminator (Fig.2)
Adjust T232 so thaqt leading of DIGITAL VOLT METER reads 0V
±
30mV.
Adjust T233 and TU201 so that distortion level reads minimum.
Adjust above both adjustment several times.
2. Multiplex (Fig.5)
Adjust VR251 so that Separation Ratio “Lch to Rch” and “Rch to Lch”
reads maximum and even level.
3. Signal Indicator Sensitivity (Fig.2)
Input signal 97.9kHz, 35.2dBf, 1kHz, 75kHz Deviation.
Adjust VR231 so that Signal (TUN.) Indicator just barely turns on.
Input signal 97.9kHz, 34.2dBf, 1kHz, 75kHz Deviation.
Confirm Signal (TUN.) Indicator turns off.
