Alignment
TX Power Output
1. Press the “Sub” band
DIAL
knob momentarily, if
needed, to switch the “Main” band to be the “Right”
band.
2. Tune the “Right” band frequency to 440.050 MHz, then
set the Transmit Power Level to “LOW.”
3. Press and hold in the in the “Left”
DIAL
knob to set
the Alignment parameter to “
b-2 PWR.xxH
.”
4. Press the
PTT
switch to activate the transmitter, and
adjust the “Left”
DIAL
knob, as needed, so that the
wattmeter reading is 5 Watts (±0.5 Watt).
5. Increase the Transmit Power Level to “MID2.”
6. Press the
PTT
switch to activate the transmitter, and
adjust the “Left”
DIAL
knob, as needed, so that the
wattmeter reading is 10 Watts (±0.5 Watt).
7. Increase the Transmit Power Level to “MID1.”
8. Press the
PTT
switch to activate the transmitter, and
adjust the “Left”
DIAL
knob, as needed, so that the
wattmeter reading is 20 Watts (±0.5 Watt).
9. Increase the Transmit Power Level to “HIGH.”
10. Press the
PTT
switch to activate the transmitter, and
adjust the “Left”
DIAL
knob, as needed, so that the
wattmeter reading is 35 Watts (±0.5 Watt).
11. Tune the “Right” band frequency to 146.050 MHz, then
set the Transmit Power Level to “LOW.”
12. Press the
PTT
switch to activate the transmitter, and
adjust the “Left”
DIAL
knob, as needed, so that the
wattmeter reading is 5 Watts (±0.5 Watt).
13. Increase the Transmit Power Level to “MID2.”
14. Press the
PTT
switch to activate the transmitter, and
adjust the “Left”
DIAL
knob, as needed, so that the
wattmeter reading is 10 Watts (±0.5 Watt).
15. Increase the Transmit Power Level to “MID1.”
16. Press the
PTT
switch to activate the transmitter, and
adjust the “Left”
DIAL
knob, as needed, so that the
wattmeter reading is 20 Watts (±0.5 Watt).
17. Increase the Transmit Power Level to “HIGH.”
18. Press the
PTT
switch to activate the transmitter, and
adjust the “Left”
DIAL
knob, as needed, so that the
wattmeter reading is 50 Watts (±0.5 Watt).
TX Deviation
1. Press the “Sub” band
DIAL
knob momentarily, if
needed, to switch the “Main” band to be the “Right”
band.
2. Tune the “Right” band frequency to 440.050 MHz, then
set the Transmit Power Level to “LOW.”
3. Press and hold in the in the “Left”
DIAL
knob to set
the Alignment parameter to “
b-3 DEV.xxH
.”
4. Inject a 1 kHz audio tone at a level of 80 mV from the
Audio Generator.
5. Press the
PTT
switch to activate the transmitter, and
adjust the “Left”
DIAL
knob, as needed, so that the
deviation meter reading is 4.5 kHz (±0.2 kHz) (USA
Version: 4.2 kHz (±0.2 kHz)).
6. Tune the “Right” band frequency to 146.050 MHz, then
set the Transmit Power Level to “LOW.”
7. Press the
PTT
switch to activate the transmitter, and
adjust the “Left”
DIAL
knob, as needed, so that the
deviation meter reading is 4.5 kHz (±0.2 kHz) (USA
Version: 4.2 kHz (±0.2 kHz)).
DCS Tx Deviation
1. Press the “Sub” band
DIAL
knob momentarily, if
needed, to switch the “Main” band to be the “Right”
band.
2. Press and hold in the in the “Left”
DIAL
knob to set
the Alignment parameter to “
b-4 DCS.xxH
.”
3. Tune the “Right” band frequency to 440.050 MHz, then
activate DCS with the 023 DCS code, and set the Trans-
mit Power Level to “LOW.”
4. Press the
PTT
switch to activate the transmitter (with
no microphone input), and adjust the “Left”
DIAL
knob, as needed, so that the deviation meter reading
is between 0.60 kHz and 0.80 kHz.
5. Tune the “Right” band frequency to 146.050 MHz, then
activate DCS with the 023 DCS code, and set the Trans-
mit Power Level to “LOW.”
6. Press the
PTT
switch to activate the transmitter (with
no microphone input), adjust the “Left”
DIAL
knob,
as needed, so that the deviation meter reading is be-
tween 0.60 kHz and 0.80 kHz.
