INTRODUCTION
The PCL 6000 System, manufactured by Moseley Associates,
Inc., is a Studio-to-Transmitter Link (STL) and is designed
to convey FM program material from a studio site to a
transmitter site. In keeping with its predecessors, the PCL
6000 is easy to operate and maintain. This manual is a
comprehensive guide with information on installation,
operation, theory of operation, alignment procedures for
customer troubleshooting and repairs, module descriptions,
schematic and assembly drawings, and parts lists.
If you are not familiar with the basic use of the instrument
and want more detailed information, please read Sections 1
through 3 before installing the PCL 6000.
Section 1, System Characteristics, is a brief overview on
the PCL 6000. It includes specifications on transmitter and
receiver, system features and system description.
Section 2, Installation, covers unpacking, installation and
checkout procedures. It also describes antenna
interconnections and remote control procedures.
Section 3, Operation, discusses the Controls and adjustments
for the PCL 6000 system that the user will encounter in
normal operation and initial setup.
Section 4, Module Characteristics, is a detailed analysis on
the theory of operation for each module component in the
Transmitter and Receiver.
Section 5, Alignment Procedures, covers system performance
checks and customer adjustments that are used to service and
maintain the PCL 6000. This section also covers recommended
test equipment for each alignment procedure and a
troubleshooting guide.
Section 6 describes general procedures for customer
assistance by telephone consultation, field repair or return
of equipment.
Section 7 contains assembly drawings and schematics for the
transmitter and receivers.
Section 8 is comprised of parts lists for the STL system.

SYSTEM CHARACTERISTICS
1 . 1 INTRODUCTION
The Model PCL 6000 Studio-to - Transmitter Link (STL) is
designed to convey FM program material from a studio site to
a transmitter site. The PCL 6000 also simultaneously conveys
control and secondary programming subcarriers. This
equipment may also be used to provide high-quality program
transmission in intercity relay service.
The PCL 6000 series of equipment is a family of equipment
that can operate in several bands from 150 MHz through 960
MHz.

The
PCL
6010
Transmitter
is
a
high-fidelity
broadband
FM
transmitter
with
a
power
output
of
S
to
8
watts.
It
is
capable
of
transmitting
the
program
signal
and
two
multiplex
subcarriers
with
little
degradation
of
signal
quality
over
one
link.
The
linearity
and
FM
noise
characteristics
of
the
direct
FM
oscillator
are
exceptional.
The
transmitter
is
modular
in
construction
and
operation,
and
the
system
description
given
below
follows
the
signal
flow
through
the
various
modules.
Audio
Processor
(A6)
Three
signal
inputs
are
provided
to
the
Audio
Processor
module:
one
audio
(composite
or
mono)
signal
and
tw
o
multiplex
signals.
Level
adjustments
are
provided
for
all
signals,
which
are
fed
to
summing
ampl
ifiers.
They
are
combined
into
a
single
signal
and
passed
to
the
FMO
Synthesizer
module.
FMO
Synthesizer
(A2)
The
baseband
signal
(Audio
MUX)
is
used
to
modulate
the
frequency
modulated
oscillator
(FMO)
in
the
FMO
Synthesizer
module.
The
FMO
is
a
60-80
MHz
ultralinear,
very
low
noise
oscillator.
This
oscillator
is
phase
locked
to
a
crystal-
controlled
reference
oscillator
.
The
phase
lock
loop
contains
the
frequency
programming
switches
which
allow
the
synthesizer
to
be
changed
in
frequency
by
25
kHz
increments.
The
RF
output
of
the
60
-8
0
MHz
FMO
then
goes
through
a
low-
pass
filter
to
attenuate
any
harmonics.
With
100%
composite
(mono)
stereo
modulation
,
the
RF
signal
will
deviate
+/
-
50
(40)
kHz
from
the
chosen
center
frequency.
The
output
power
at
this
point
is
approximately
1
milliwatt.
Up
Converter
(A3,
A4,
AS)
To
preserve
the
low
noise
and
low
distortion
characteristics
of
the
FMO
,
the
traditional
method
of
multiplying
up
was
avoided.
Instead,
a
scheme
was
chosen
consisting
of
a
single
up-conversion
utilizing
a
local
oscillator
operating
at
the
output
frequency
plus
or
minus
the
FMO
frequency.
This
process
takes
place
in
the
Up
Converter
module.
The
signal
from
the
FMO
enters
one
port
of
the
double
balanced
mixer;
the
signal
from
the
first
LO
enters
the
LO
port
of

the
double
balanced
mixer.
The
output
of
the
mixer
contains
both
the
sum
and
difference
frequencies
of
the
two
input
signals.
The
frequency
required
is
selected
by
the
bandpass
filter,
which
eliminates
all
other
mixer
products.
The
output
level
at
this
point
is
approximately
+10
dBm.
The
signal
is
then
fed
t o
the
intermediate
power
amplifier
(IPA)
,
which
has
about
30
dB
of
gain.
This
raises
the
level
of
the
signal
sufficiently
to
drive
the
final
RF
amplifier.
The
output
frequency
of
the
Up
Converter
is
controlled
by
the
frequency
set
by
the
FMO
synthesizer.
This
can
be
set
in
25
kHz
steps
from
60
-
80
MHz.
The
60-80
MHz
signal
is
mixed
with
the
fixed
first
LO
(1020
MHz
for
the
950
MHz
band)
to
obtain
the
final
output
frequency.
Other
bands
use
the
same
FMO
range
with
a
different
LO
frequency.
