METERING AND STATUS
PGM LVL (R171)
Adjusts the PGM LEVEL meter function. 100% = 0 dB.
AFC LVL (R166)
AFC level metering adjust. Center arc.
LO1 (R169)
1st LO relative level. Center arc.
LO2 (R168)
2nd LO/synthesizer relative level. Center arc.
LO3 (R167)
3rd LO relative level (PCL6030). Center arc.
MUX LVL (R170)
Adjusts the MUX LVL function of the meter. A reading of 5 on the
lower scale equals 5 kHz of the main carrier by the subcarrier.
SIG LVL (R172)
Used to adjust the RF LEVEL function. A reading of 3 K on the center
scale of the meter equals 3000
μ
V of input signal.
+5V (R213)
Power supply metering adjustments.
+15V (R210)
-15V (R212)
METER BALLISTICS (R196)
Adjusts the meter ballistics.
METER ZERO (R186)
Adjusts meter zero.
MUTE AND TRANSFER
The Mute and Transfer section requires no adjustment. If a failure is suspected in the Mute and
Transfer circuitry, the following information may be useful in isolating the problem:
1.
A mute signal from the IF Demod (Mute Threshold Adjust LED red) will de-energize the
mute relay and disconnect the composite and MUX audio outputs.
2.
This module may be externally muted, either by a remote mute input or a transfer input
from a receiver transfer panel (TPR).

Receiver RF Module
PRESELECTOR FILTER (950 MHZ, PCL6020/6030)
Filters FL-12 and FL-11 (in the RF module) are two- and three-pole helical filters with a passband
of approximately 20 MHz. Under normal circumstances, no alignment is required. To check
alignment, a sweep oscillator, whose frequency is centered in the middle of the RF band used, is
injected into RF IN and the signal is monitored at IF OUT. The five adjustments should be set for
a flat passband greater than 5 MHz wide.
PRESELECTOR FILTER (950 MHZ, PCL6060)
The filter is located under the Audio/Power Supply board of the receiver (see system assembly
drawing). The filter has a passband of approximately 20 MHz. Under normal circumstances, no
alignment is required. To check alignment, a sweep oscillator, whose frequency is centered in the
middle of the RF band used, is injected into RF IN and the signal is monitored at IF OUT. The five
screw adjustments should be set for a flat passband greater than 5 MHz wide.
PRESELECTOR FILTER (220–450 MHZ)
The filter is located at the rear of the receiver (see system assembly drawing) and has a
passband of approximately 8 MHz. This can be tuned by observing the RF LVL on the meter and
peaking the three adjustment capacitors of the filter. Take care not to adjust the LO filter which is
located on the same bracket. The preselector filter is the one that is connected directly to the
ANTENNA port.
