DEVIATION
Transmitter Deviation is increased or decreased by first keying the radio via F6, and then by
pressing the UP/DOWN arrow keys respectively. A relative deviation value will be displayed, but
the actual transmitter deviation must be determined from your service monitor. The radio will
transmit on the test frequencies displayed on the screen and should be terminated into a 50 ohm
load or service monitor.
Using the UP/DOWN arrow keys, adjust Tx Deviation per your User's Manual. Press F6 again to
de-key the radio, the value will be programmed into the radio.
NOTE: For fast changes, keyin the value and press the Enter button.
LOW PORT MODULATION
Low Port Modulation is increased or decreased by first keying the radio via F6, and then by
pressing the UP/DOWN arrow keys respectively. A relative modulation value will be displayed.
The radio will transmit on the test frequencies displayed on the screen and should be terminated
into a 50 ohm load or service monitor.
Using the UP/DOWN arrow keys, adjust the modulation per your User's Manual.
Press F6 again to de-key the radio, and the value will be programmed into the radio.
NOTE: For fast changes, keyin the value and press the Enter button.

Low Port Modulation
Tuning Frequency:
Automatic - Frequency displayed on Tuning screen.
Deviation Setting:
375 Hz +/- 40 Hz for 12.5 kHz channel spacing,
750 Hz +/- 40 Hz for 20/25/30 kHz channel spacing.
• Set the radio into TX low power mode. The Modulation
Analyzer should be set as follows:
FM
PEAK+
15 kHz LP Filter “ON”
All HP Filters “OFF”
De-emphasis “OFF”
• Use the up/down arrow keys to change the low port
deviation setting and the F6 key to toggle the PTT.
NOTE
The low port tuning tone is automatically
generated internally by the radio. No external
modulation injection is required.
VCO Deviation Adjustment
Tuning Frequency:
Automatic - Frequency displayed on Tuning screen.
Deviation Setting:
2.2 kHz +/- 100 Hz for 12.5 kHz channel spacing,
4.6 kHz +/- 200 Hz for 20/25/30 kHz channel spacing.
• Set the radio into TX low power mode.
• Inject a 110 mV rms, 2 kHz audio signal into the
external mic using the radio test box.
• The Modulation Analyzer should be set as follows:
FM
PEAK+
15 kHz LP Filter “ON”
All HP Filters “OFF”
De-emphasis “OFF”
• Use the up/down arrow keys to change the deviation
setting and the F6 key to toggle the PTT.
Они предлагают настраивать по их сервисному анализатору
В самой программе есть куча регулировок , что из них крутить , пока не понятно . будем методом тыка .
Лоу порт вроде бы не добавляет ничего . Стояло число 29 , из максимальных 31.
В разделе девиации 8 регулировок . ну буду пробовать по одной добавлять , и проверять , как меня слышат )))
вот фото из программы
