RDS FUNCTION
The ATS-909X incorporates circuitry to receive FM stations
transmitting an RDS (Radio Data System) signal. When
receiving an RDS station the display will show the station
call letters and if the RDS station is also transmitting a CT
function (clock time) it will automatically correct the time
every minute. It is important to make sure that the Home
Time (as described under “SETTING THE CLOCK (REAL
TIME)” is set correctly. In addition if your time zone is
operating under Daylight Savings Time make sure the DST
(Daylight Savings Time) function is disabled. For the clock
time function to operate the following conditions must exist:
a.
TIME SET switch must be set in the AUTO position.
b.
Radio must be on FM band.
c.
Radio must be tuned to an FM station transmitting RDS
CT function.

NOTE
When receiving an RDS station, the RDS is indicated
with an icon in the display.
SINGLE SIDE BAND (SSB) RECEPTION
SSB is very popular among ham and business radio
users because of its signal intelligibility superiority. Many
amateurs who operate SSB and transmit below 10 MHz
generally use the lower side band (LSB) while amateur and
commercial stations transmitting above 10 MHz generally
use the USB. Your ATS-909X is equipped to receive all
USB and LSB transmissions. To receive SSB stations:
1.
Turn the set on.
2.
Extend the telescoping antenna full length and position
upright or use external antenna.
3.
Set the RF Gain Control to maximum.
4.
Select the SW band as described in “SELECTING AN
SW BAND”.
5.
If frequency of SSB station sought is known enter the
frequency in accordance with earlier instructions.
6.
You may also scan the band for SSB stations by slowly
rotating the Rotary Tuning Knob through the selected
band, tuning for the best intelligibility and watching for
deflections on the Signal Level Indicator in the display.
SSB transmit with a “suppressed carrier” meaning
the Signal Level Indicator in the display will fluctuate
only when there is a voice transmission and not during
pauses in voice transmission.
7.
As soon as you have located a SSB station (you will
not be able to understand the speech) switch to SSB
reception by depressing the Mode button. Continue
pressing of the Mode button will alternate between
USB and LSB. Try LSB for frequencies below 10 MHz
or USB for frequencies above 10 MHz.
8.
After tuning for maximum intelligibility switch STEP
switch to Slow position and readjust Rotary Tuning Knob
for maximum intelligibility.
DAYLIGHT SAVING TIME
Daylight saving time is the practice of temporarily
advancing clocks during the summertime so that
afternoons have more daylight and mornings have less.
Press the Daylight Saving Time switch and the radio clock
time will be adjusted one hour forward.
SWITCH SETTING
AM NARROW / WIDE
For normal operation it is suggested that this switch be
used in the wide position. If occasion arises where an
adjacent station interferes with the station being listened to
the AM Narrow / Wide switch should be put into the narrow
position.
However, the above applies to AM bandwidth in AM mode
only, not for SSB (LSB or USB) mode. For SSB (LSB or
USB) mode, the station is only being put into the narrow
position.
STEREO RECEPTION
The ATS-909X is designed to receive FM stereo
broadcasts with headphones connected to the stereo
headphone jack. Switch FM STEREO / MONO must be
placed in the stereo position. Stereo icon will appear in the
LCD display if headphones are connected.
TONE CONTROL
You can adjust the tone performance of your radio
depending on the type of radio program you are listening
to. Switch the Tone Control switch to News mode for
listening to news program or AM band to reduce the hiss
