June 1997
Part No. 001-3412-002
4. Arrow to the "mid" channel the DAC value should
be "125" (the voltage at the wiper of R827 should be
set to 1.5V DC). If the square wave is rolled off on
the edges, adjust R825 up in value to achieve as flat
a square wave as possible. If the square wave is
peaked on the edges, adjust R825 down in value to
achieve as flat a square wave as possible.
5. Adjust the DAC value using CTRL Page Up/Page
Down to fine tune the DAC value for the latest
square wave (see Figure 6-2).
6. If the radio/loader combination is to stay together as
one unit, press F10 to save the values to the loader
EEPROM.
7. Repeat the previous two steps at the Low and High
channels.
8. Arrow down to Square Wave and arrow over to shut
the square wave off.
9. Arrow up to Tx Audio Mode and arrow over to
Wide AC.
10.Input a 100 Hz sine wave. With the modulation
analyzer 15 kHz low pass filter selected. Adjust the
audio analyzer output level to achieve a transmit
deviation of:
fd= 1.5 kHz for 12.5 kHz radios
fd= 3.0 kHz for 25 kHz radios
11.Arrow to the Low channel, input a 100 Hz sine
wave and set a 0 dB reference on the MOdulation
Analyzer. Input a 1 kHz sine wave, the level should
be within ±0.5 dB of the reference at 100 Hz.
12.Arrow to the "mid" channel, input a 100 Hz sine
wave and set a 0 dB reference on the MOdulation
Analyzer. Input a 1 kHz sine wave, the level should
be within ±0.5 dB of the reference at 100 Hz.
13.Arrow to the High channel, input a 100 Hz sine
wave and set a 0 dB reference on the MOdulation
Analyzer. Input a 1 kHz sine wave, the level should
be within .05 dB of the reference at 100 Hz.
14.Unkey the transmitter by pressing F6.
