(A) In CH70, every time you are in transmit mode, (every time you press PTT), the
following test tone can be outputted:
1st transmission: 1300 Hz
2nd transmission: 2100 Hz
3rd transmission: No modulation
4th transmission: Synthetic tone of 1300 Hz and 2100 Hz
5th transmission: Return to 1st transmission
(B) Scan the channels between WX10 and EXP04 in the SCAN mode.
Starting Test Mode
Confirm that
PWR/VOL
switch is off, and short the TEST points(JP1001). Turn on the
PWR/VOL
switch while press and holding the
DIST
and
DW
keys.
Adjustment of VCO
Connect the DC voltmeter to the test point (LOCK TP).
Use the
16/9
key to set the channel to
CH16
, adjust TC1002 so that voltage on the
TP1010 is 1.5 V ±0.1 V in the receive and transmit mode.
Use the
16/9
key to set the channel to
CH16
, adjust TC1001 so that voltage on the
TP1007 is below 3.0 V ±0.1 V in the transmit mode.
Adjustment of Transmit Power
Adjust power at high and low in the transmit mode, and confirm power in the specified
bandwidth.
Connect the wattmeter and 50-ohm dummy load to the antenna jack.
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.
Adjustment of PLL Frequency
Adjust the frequency in the transmit mode and local frequency in the receive mode.
Setup the test equipment as shown below.
Set the channel to
CH16
. With the
PTT
switch pressed, adjust
TC1003
so that RF
frequency is 156.80000 MHz ± 100 Hz.
Adjustment of Deviation
Adjust deviation in the transmit mode.
Setup the test equipment as shown below.
Set the channel to
CH16
.
Set the output of the audio generator (AG) to 1 kHz and 100 mV.
