Optimizing ATS Frequency Storage Results
The storage results of Auto Tuning Storage (ATS) depend on a variety of factors:
● Longwave (LW) and Medium Wave (MW) signals are directional. Adjusting the direction of the rotatable
antenna can improve the reception.
● Due to the nature of radio wave propagation, the number of longwave and medium wave broadcasts
received at night is greater than during the day.
● For shortwave, radio wave propagation is affected by ionospheric changes (different time periods in the
morning, noon, and evening, different seasons, sunspot cycles, etc.).
● Broadcasts may only take place during specific hours of the day.
● The receiving environment (geographical or local sources of interference) and the receiving equipment
(such as the antenna) impact the results.
By adjusting the capture threshold levels of the signal strength and signal-to-noise ratio, it is possible to try
and improve the auto tuning and storage results for LW, MW (AM), SW and FM under different signal
receiving conditions.
If the threshold levels for the signal strength and signal-to-noise ratio are set high, the capture sensitivity is
low, which means that broadcasts with weak signals will be missed. If the threshold levels for the signal
strength and signal-to-noise ratio are set low, the capture sensitivity is high, which will result in radio noise
mistakenly being regarded as radio signals and are stored into memory.

Because broadcasts in the MW (AM) and SW bands may only be available during a certain time of day, you
can use ATS in Auto Paging (AP) mode to automatically search and store in the time-specifcfrequencies
as indicated in Table 2 on page 14 frequencies,memory pages 01-24 . Subsequently, when using AP to recall
frequencies a it will only show the that are stored in the memory pages of the current time period. In way, you
can then use pages 01-24 to create a broadcast frequency schedule.
● Medium Wave (AM) frequencies stored with AP ATS between 09:00 - 12:59 are automatically stored on
pages 09, 10, 11, and 12, frequencies stored between 13:00 - 16:59 are stored on pages 13, 14, 15 and 16.
When using AP to recall frequencies at 12:30, it will only show those frequencies stored in the 09:00 -
12:59 time period. In this way, it is possible to create 6 time-specific memories for MW (AM).
For example:
● Shortwave (SW) frequencies stored with AP ATS between 11:00 - 11:59 are automatically stored on page
11, frequencies stored between 17:00 - 17:59 are automatically stored on page 17. When using AP to
recall frequencies at 17:20, it will only show those frequencies stored on page 17. In this way, it is possible
to create 24 time-specific memories for SW.
Using AP ATS to Create Time-Specific Memories for MW (AM) and SW
Please make sure that the clock of your S-2200x has been correctly set
before using this feature (see page 8).
In the example on the right, "20ch", "MW" and “11” indicate that 20
medium wave broadcast frequencies were stored on page 11 during
AP ATS that took place between 11:00 - 11:59. Because 11:00 - 11:59
belongs to the 09:00 - 12:59 time interval (see Table 2 on page 14), all 20
medium wave frequencies are available on memory pages 09, 10, 11, and 12.
1) Press and hold the [ AP ] (PAGE ) button . “AP” is displayed
behind the frequency, indicating that the AP mode is entered, as
shown in the figure on the right.
2) Select the MW or SW frequency band.
3) Press and hold the related band button ([ MW/LW ], [ SW ] or [ SW ]) to initiate the AP auto tuning
and storage (ATS) feature.
4) When AP ATS is completed, the frequency band, time-specifc page number, and the number of
stored frequencies are displayed. To stop AP ATS before it has finished, rotate the main tuning knob.
Notes:
● There are two AP ATS modes for SW:
Mode A: Press and hold the [ SW ] button to scan and store broadcasts within all meter bands.
Mode B: Press and hold the [ SW ] button to scan and store broadcasts within the selected meter band.
● The ATS feature will replace any previously stored frequencies that are already available in the time-
21
AUTO PAGING (AP) MODE: TIME-SPECIFIC MEMORIES FOR MW (AM) AND SW
specific memory pages (pages 01-24). For example, if memory page 11 already contains frequencies that
were previously stored with other storage methods (manual storage, auto scan storage, ATS) then these
will be replaced when performing AP ATS during the 09:00 - 12:59 time interval.
● It is possible to perform AP ATS for FM and LW, but this will only replace the frequencies that are already
stored in memory pages 01-24 and not create time-specific memories. To automatically tune and store FM
and LW memories in pages 01-24, please use Auto Tuning Storage (ATS) as indicated on page 16.
● If there is a time period change during AP ATS, the device will stop scanning and delete all frequencies
stored in the previous time period, after which it automatically re-scans and stores the frequencies into the
new time period.
AP Manual Storage
If AP ATS missed certain frequencies (e.g. due to interference), then it is possible to add these manually:
1) Quick press the [ VF/VM ] (SCAN) button . The frequency flashes twice and enters VF mode.
2) Select the band and frequency.
3) Quick press the [ M ] button . “ PRESET ” flashes in the top right corner of the display.
4) Press and hold the [ PAGE ] (AP) button. “ ” and “ PRESET ” flash on the display.
5) Quick press the [ M ] button to confirm.
If the threshold levels for the signal strength and signal-to-noise ratio are set high, the capture sensitivity is
low, which means that broadcasts with weak signals will be missed. If the threshold levels for the signal
strength and signal-to-noise ratio are set low, the capture sensitivity is high, which will result in radio noise
mistakenly being regarded as radio signals and stored into memory.
Optimizing ATS Frequency Storage Results in Auto Paging (AP) Mode
The factors influencing the results of ATS in AP mode are the same as described for ATS on page 17. By
adjusting the capture threshold levels of the signal strength and signal-to-noise ratio, it is possible to try and
improve the ATS results in AP mode for MW (AM) and SW under different signal receiving conditions.
