Adjust
EEPOT
7
until
the
transmitted deviation level reaches 60%
full
system deviation
as
indicated in Table
4-8.
If
the
deviation level could not be set, adjust
EEPOT E
to select the
appropriate range (0 through 3)
of
EEPOT
7.
Repeat
step
11.
Remove
the test tone.
Release the
PL Dis/Xmit
switch.
Receiver Level Adjustment
4-38
The following procedure adjusts
the
receiver level deviation for the repeater
mode of operation.
For
stations configured as base
stations,
a
relative level can
be
measured on the
SSCB which
is equivalent to the repeater
deviation level. For
stations
containing
the
Spectra-TAC/DIGITAC
Encoder Option
(C269),
the
receiver
level should
be
adjusted
during in-cabinet
repeat operation.
1.
Inject
a
lmV
RF
receive signal, modulated
with
a
1
kHz
tone at 40%
full
station deviation,
as
indicated in Table
4-8, into the receiver antenna
connector on the
Junction
Box.
Refer
to
Figure
4-21
for the antenna connector locations.
Set the R1
PL DT MUXbus
bit
(A3/D2).
2.
NOTE
Steps
3
through step
9
apply only
to
stations
configured
as repeaters.
If
the station is
configured
as
a
base station
(half-duplex with
antenna relay or
full-duplex
base station) or is
a trunked station
with
a
Spectra-TAC/DIGITAC
Encoder Option
(C269), proceed
to step
10.
If this
is
a trunked station,
disconnect
the
trunking
cable from
Junction
Box
connector (J3).
3.
Key
the
transmitter
by
connecting
a
jumper wire jumper from J2901-8
(TKG PTT)
to J2901-1
(LOGIC GND)
on the
TTRC
logic
board.
Refer
to
Figure
4-22 for the connection locations.
4.
Set and hold
the
PL Dis/Xmit
switch
to
Xmit
to
strip off any
TDATA
or
PL/
DPL.
5.
Verify
the transmitted deviation level
is at 60%
full
station
deviation
as
indicated in Table
4-5.
6.
This
setting provides
+3.5
dB of repeater gain. If this level is out of
adjustment,
set
it by adjusting
EEPOT
5.
If unity gain
is desired, set for 40%
full system deviation.
