Use
the
H/L
key to set transceiver to
high power
and set the channel to
CH16
. With
the
PTT
switch pressed, adjust
VR1001
so that RF power is 25 W.
Use
the
H/L
key to set transceiver to
low power
and set the channel to
CH16
. With
the
PTT
switch pressed, adjust
VR1002
so that RF power is 0.8 W.
-- Confirmation --
Use
the
H/L
key to set transceiver to
high power
and set the channel to
EXP01
. With
the
PTT
switch pressed, confirm that RF power is between 23 W and 27 W.
Use
the
H/L
key to set transceiver to
low power
. With the
PTT
switch pressed,
confirm that RF power is between 0.5 W and 1.0 W.
As descried above, confirm RF power at
EXP04
and
EXP05
. Set transceiver to
high
power
and confirm that RF power is between 23 W and 27 W. Set transceiver to
low
power
and confirm that RF power is between 0.5 W and 1.0 W.
Adjustment of PLL Frequency
Adjust the frequency in the transmit mode and local frequency in the receive mode.
-- Adjustment --
Setup the test equipment as shown below.
Set the channel to
CH16
. With the
PTT
switch pressed, adjust
TC1001
so that RF
frequency is 156.80000 MHz ± 50 Hz.
Adjustment and Confirmation of Deviation
Adjust deviation in the transmit mode.
-- Adjustment --
Setup the test equipment as shown below.
Set the channel to
CH16
.
Set the output of the audio generator (AG) to 1 KHz and 150 mV.
With
the
PTT
switch pressed, adjust
VR1003
so that the maximum deviation is ±4.5
KHz.
Decrease the output level of AG by 20 dB (the output level of AG should be 1/10).
With
the
PTT
switch pressed, adjust the output level of AG so that the deviation is ±3.0
KHz.
Increase the output level of AG by 20 dB (10 times of the output level of AG) which is
supposed to be Detective Modulation Level ±4.5 KHz).
Repeat steps 3 though 6 three times so that deviation is ±3.0 KHz and the maximum
deviation is ±4.4 KHz to ±4.6 KHz.
-- Confirmation --
Set the output of the AG to 1 KHz and 150 mV.
Set the channel to
EXP01
, confirm that maximum deviation is between ±4.3 KHz and
