Note: "Special Tuning Controls" below contains more information about
using your receiver's controls.
Selecting a Band
Press ATS/FM, ATS/LW, ATS/MW, or METER/SW to select the band. (Press
ATS/MW for AM.)
To select a smaller band within the SW band, press METER/SW Again. When m
flashes on the right side of the display, enter the desired band by
pressing its labeled key on the keypad. For example, to select the
75 meter shortwave band, press 3.
Manual Tuning
You can select a lower or higher frequency by pressing TUNING UP ARROW
or DOWN ARROW. If you select SLOW, the tuning increments are smaller
so you can fine tune the frequency.
Band Fast Slow
FM 0.1 MHz 0.05 MHz
LW 9 kHz 1 kHz
MW 9/10 kHz 1 kHz
SW 5 kHz 1 kHz
AM USB/ 1 kHz 40 Hz
LSB
Note: You can tune standard AM, upper sideband (USB), and lower sideband
(LSB) frequencies. For more information, see "Tuning SSB Stations"
below.
If you set STEP to STOP, turning MANUAL TUNING has no effect at
all, so you cannot accidentally change the frequency.
Note: Setting STEP to STOP locks only MANUAL TUNING. For information
about locking the front panel buttons, see "Locking the Controls"
above.
Direct Access Tuning
Follow these steps if you know a station's frequency and want to directly
tune to that station.
1. Press F/FREQ. The frequency display disappears and FREQ flashes for
about 30 seconds.
2. Use the number keys and symbol to enter the frequency, then press
ENTER symbol.
Notes: If you wait more than 30 seconds to press a button, the
previous frequency returns to the display. Begin again at
Step 1.
If you make a mistake, press C (cancel) to erase the last
digit, then enter the correct digit.
Scan Tuning
To automatically tune up or down to the next active frequency in the
selected band, hold down TUNING UP ARROW or DOWN ARROW for about 1 second.
The receiver scans up or down the selected band and tunes to the firs
frequency it finds with a strong signal.
To scan for an SW (shortwave) frequency in one of the 14 meter bands,
press SW, press the number button with the meter range you want to scan,
then press TUNING UP ARROW or DOWN ARROW to scan the band.
Notes: When scanning, the receiver only searches for frequencies with
strong signals. To search for stations with weaker signals,
use one of the manual tuning methods.
When scanning in a lower band, the receiver searches only within
the selected band and stops at the upper and lower limits of the
band.
Your receiver shows the shortwave bands, you can receive on the
bottom of the display.
Adjusting The Tone
Set TONE to NEWS to enhance broadcast voices while listening to talk
shows or news programs on SW, MW, and LW frequencies.
Set TONE to MUSIC to enhance treble and bass response when listening to a
music program (especially FM programs).
Set TONE to NORM to help reduce interference.
Special Tuning Controls
STEREO/MONO-FM
You can receive FM stereo by connecting stereo headphones to the headphone
jack and setting STEREO/MONO-FM on the right side of the receiver to
STEREO.
To improve reception for weak FM stereo stations, set STEREO/MONO-FM to
MONO-FM. The sound is no longer in stereo, but the reception should
improve.
WIDE/NARR.-AM
A strong station that broadcasts close to a frequency you turned might
interfere with that frequency. To reduce interference from adjacent
stations in the SW, MW, or LW bands, set WIDE/NARR.-AM on the right side
of the receiver to NARR.-AM. Or, if there is no interference, set it to
WIDE for better sound.
AM RF GAIN on the left side of the receiver lets you tune a received
signal for the best SW reception. If the signal is weak, turn AM RF GAIN
toward +. If the sound is distorted, turn AM RF GAIN toward -.
Tuning SSB Stations
SSB (single sideband) is very popular among amateur radio and business
radio users because its superior signal quality. Many amateurs who
operate SSB and transmit below 10 MHz generally use LSB (lower sideband),
while amateur and commercial stations who transmit above 10 MHz generally
use USB (upper sideband). Your receiver receives both USB and LSB
transmissions.
Follow these steps to receive SSB stations.
1. Select an SW band (see "Selecting a Band" on Page 18).
2. If you know the frequency of an SSB station, enter that frequency.
Or, scan the band for SSB stations by slowly rotating MANUAL TUNING,
tuning through the selected band until you hear an SSB station.
Or, scan the band for USB or LSB stations by holding down TUNING
DOWN ARROW or TUNING UP ARROW for about 2 seconds until you hear
an USB or LSB station.
Note: SSB stations sound distorted when you tune to them in the
normal SW band. To help you find SSB stations, watch for
deflections on the signal strength indicator. Since SSB
is transmitted with a suppressed carrier, the signal strength
indicator will move more quickly when there is a transmission
and more slowly during pauses in the transmission.
3. When you have located an SSB station, press AM MODE to receive the
transmission. Repeatedly press AM MODE to switch between USB or
LSB transmissions (try LSB for frequencies below 10 MHz or USB
for frequencies above 10 MHz).
4. Set STEP to SLOW then readjust MANUAL TUNING for maximum
intelligibility.
Using RDS
The receiver displays information about FM radio stations that transmit
a Radio Data System (RDS) signal. When the receiver receives an RDS
station, the station's call letters appear on the display. Also, if
the station broadcasts CT (clock time) information, the receiver
automatically corrects the displayed time.
Follow these steps to use RDS.
1. Turn on the receiver.
2. Tune the receiver to an FM station that transmits RDS (and CT)
information.
3. Set TIME SET on the right side of the receiver to AUTO.
4. Make sure that your local time (as described in "Setting and Viewing
the Local Time" above) has been set correctly. (The receiver compares
the CT information with your local time to display the correct time at
the broadcaster's location).
5. If your time zone is using Daylight Saving Time, repeatedly press
symbol until symbol appears.
Memory Functions
Besides tuning to the preprogrammed shortwave stations (see "Tuning Pre-
programmed Shortwave Stations" above), you can store and then quickly tune
up to 94 frequencies in your receiver's memory locations. The memory
locations are grouped into pages (nine memory locations per page).
You can store up to 18 FM frequencies (2 pages), 18 MW frequencies (2
pages), and 9 LW frequencies (1 page) into your receiver's FM/MW/LW
memory locations. You can store frequencies automatically (see "Automatic
Storage") or manually (see "Manual Storage").
Additionally, you can store frequencies into any empty memory location
in the receiver's SW memory pages (see "Storing SW Frequencies in Memory"
below). There are 40 empty locations scattered throughout the pages,
and all 9 locations in Page 29 are blank. See "DX-398 Shortwave Pages
Chart" above.
Storing FM, MW, OR LW Frequencies in Memory
Automatic Storage
You can set your receiver's automatic tuning system (ATS) so it
automatically stores all available FM, LW, and MW stations (from strongest
to weakest) in the FM, LW, and MW memory locations until all the memory
locations are occupied. This feature helps you find local stations in
another city by simply pressing a memory location button.
Note: You cannot use this feature to store SW stations.
To use ATS, hold down ATS/FM, ATS/LW, or ATS/MW for about 3 seconds. The
receiver beeps and the selected band and ATS flash. Then the receiver
automatically scans and stores the strongest frequency into the first
available memory location. It continues to scan and store frequencies
until it fills the nine memory locations in that page.
The first stored station appears. Once the receiver has stored nine
stations in Page 1, press PAGE to select the next page. Then hold down
ATS/FM or ATS/MW again to store the other available frequencies. The
receiver beeps when it flashes automatically tuning stations.

Notes: PAGE flashes only when the receiver is set to SW mode.
If you wait more than 10 seconds to press PAGE, PAGE stops
flashing.
If you pressed ATS/LW in Step 1, PAGE does not appear because
there is only one LW page.
4. Press M/MEM. MEMO flashes for about 12 seconds. The number for the
first available empty memory location for the selected page flashes
next to MEMO.
Note: If an empty memory location number does not flash, all memory
location are full in the band you selected. If this
happens, clear a memory location (see "Delete a Station You
Stored" above) then store the frequency. Or, to replace
a stored frequency with a new frequency, repeatedly press
TUNING DOWN ARROW or TUNING UP ARROW to select a new frequency,
press M/MEM, then press the number key for the memory location.
After a few seconds, the receiver beeps and stores the new
frequency in the memory location.
