Confirmation of Weather Alert Tone

Confirmation of Weather Alert Tone
In the weather channel mode, when transceiver receives the specific emergency tone
(1050 Hz), weather alert tone will be output (Weather Alert Operation). The Weather
Alert mode will be active when a NOAA weather channel is in memory and radio is in
memory scan or P-scan mode.

Connect the standard signal generator (SSG) to the antenna jack.

!

 

Squelch position set to tight.

!

 

Press the 

SCAN

 key and start to Memory Scan mode.

!

 

Set the SSG to 163.275 MHz (WX10) and output level of the SSG to 20 dBµV, ±3.0
KHz deviation with 1050 Hz tone modulation.

!

 

Set the output of the SSG to ON.

!

 

Confirm that the channel of transceiver stops at WX10 and the transceiver
outputs the weather alert tone (1050 Hz).
