for general SSB receiuer test.
This test determines if
the
SSB receiver is operating
properly before being tested for complete specifica·
tions. Checking all channels will
indicate
any
defec·
tive
synthesizer cryGtals
Or
defective
PPL
program·
ming switch contacts.
The setting
of
the
clarifier (voice lock) control
is
ne<:essary before any
other
receivcr tests are made.
Once
the
clariner
is
set
a$
indicated in
this.
general
test,
it
should
be
left
at
the
final
setting for all
other
tests.
If
the
clarifier
is
not
mechanically centered
at
the
conclusion
of
the
test,
the
manufacturer's instruc.
tions for centering should
be
consulted.
To
test
the
general operation
of
the
SSB receiver:
1. Supply
the
proper power
to
the
SSB receiver.
2.
Conne<:t
the
output
of
the
CB42's RF·IF
OUT·
"
PUT jack
to
the
antenna
input
of
the
receiver
using
the
supplied RF cable.
3.
Connect
the
receiver's audio
output
to
the
SPEAKER SUB Input jack using
the
supplied
audio cable. Set
the
SPEAKER SUB switch for
the
same impedance as
the
output
ot
the
receiver.
1. Make an audio conneetion from
the
SPEAKER
SUB
input
to the 1 MEG COUNTER
input.
The
use
of
an audio
"Y"
adapter available through
most electronics parts distributors will assist in
making this connection.
S.
Set
the
CB
RF
TUNER and
the
