WX-200 Audio Adjustments
Transmit audio from the controller has a direct connection to the transmitter through the WX-200.
There is no need to readjust transmitter deviation. Press the MONITOR switch [SW3] on the rear
panel. Monitor the transmitter output. Adjust the LINE LEVEL audio control R25 for the desired level
of NOAA weather station audio.
Press the FIP CODE switch [SW2]. The voice synthesizer will announce the selected FIP codes and
voice the station ID if activated. Continue to press [SW2] as required until the VOC LEVEL audio
control R24 is adjusted for the desired voice synthesizer level. The Headphone audio output has been
factory set.
Play Test Packets
You can generate test packets with your computer’s
sound card to test the WX-200. NOTE: Insure that
during the test sequence the sound card is not
configured to apply “special effects” to the sound
files.
Connect the output of the sound card to the
modulation input of a RF signal generator. Set the
frequency to 162.XXX MHz at 3KHz deviation. If a
signal generator is not available connect a cable
from the output of the sound card to WX-200 at
TP1.
Set dipswitch #4 to ON and cycle power to reset the
WX-200 to default values. Return dipswitch #4 to
the OFF position.
Start the WX-200 program, click on the “HELP” menu and select “Play Test Packets”.
