Automatic adjustment of the MW channel step

A channel step is the basic interval unit in a frequency allocation system. The MW channel step differs from country to country (10 kHz for North and South American countries, and 9 kHz for Japan, Europe and other countries). Normally, the scanning or tuning steps needs to be adjusted to match the system for the area to scan or manually tune MW frequencies. This unit, however, determines your local area from your time zone setting (the time difference from the UTC) and automatically chooses the appropriate channel step.

The unit scans within the frequency range of the chosen band or meter band (see "Frequency range of the bands/meter bands", page 19). In the SSB reception mode, the unit scans the whole 150 to 29999 kHz frequency range.

SONY ICFSW07 - Various ways of reception (continued) Scan tuning - 2

5 Press I or I+ to stop scanning and listen to the desired broadcast.

"SCAN" disappears and the name of the band appears in the display.

Tips

  • The unit scans the frequencies in descending order when holding down I , and in ascending order when holding down I+ .
  • To change the scanning direction, hold down either I or I+ opposite to the current direction. This is convenient when, for example, you want to return to the previous reception after the unit has resumed scanning.
  • When scanning for MW broadcasts at night when reception is intense, or when scanning under prevalent interference, the unit may stop scanning to null broadcasts frequently. Switch ATT to ON and adjust sensitivity with the ATT Control (see "Controlling scan stops", below). Under normal conditions, set ATT to OFF.

Controlling scan stops — using the ATT switch and the ATT Control

Use the ATT (attenuator) switch and the ATT Control to control reception sensitivity when the unit stops scanning to null broadcasts frequently or when scanning under prevalent interference. Under normal conditions, use the radio with ATT set to OFF (i.e., with maximum sensitivity).

SONY ICFSW07 - Controlling scan stops — using the ATT switch and the ATT Control - 1

text_image ATT Control ATT

The ATT Control is activated when ATT is switched ON. Turn the ATT Control toward MAX to reduce sensitivity. The radio will skip weaker signals and stop at only stronger ones.

Note

If the ATT Control is turned too much toward MAX, the radio will not stop on any weaker signals at all. Switch ATT to OFF if you do not need to use the attenuator.

When there is no reception

If the radio was not able to receive any of the frequencies for the time zone stored in the ROM, scanning stops with a beep when the radio returns to the frequency where it started scanning.

SONY ICFSW07 - When there is no reception - 1

flowchart
graph LR
    A["Lowest frequency"] --> B["Scan start frequency"]
    B --> C["Highest frequency"]
    C --> A

Short wave reception may be difficult at times due to various factors, such as sunspot activity and atmospheric conditions. Furthermore, the major broadcast stations whose data are stored in the ROM may change the broadcast time and/or frequencies at the change of season, etc. In such cases, the radio may not be able to receive the frequencies stored in the SW STATION CALL ROM.

Updating the SW STATION CALL ROM

To conform with possible changes in frequencies, the SW STATION CALL ROM is designed to be replaceable by the user to an updated version of the ROM. The newest SW STATION CALL ROM is sold by F Corporation. The ROM is to be updated in around October every year. We recommend the ROM to be replaced at least once in 2 to 3 years.

To purchase the newest ROM, refer to "Purchasing the latest SW STATION CALL ROM" and contact F Corporation.

To exchange the ROM, see “Exchanging the SW STATION CALL ROM”, page 46.

Notes

  • Many of the worldwide broadcast programs of the major broadcast stations stored in the ROM are broadcast only at certain times of the day. If the station is not broadcasting on the scanned frequency at the time, the radio will not receive any broadcast or receive broadcast by some other station, such as a local station, broadcasting on the same frequency.
  • If the frequency is changed by manual tuning, etc., when "SW STATION CALL" indication is lit in the display, the radio will exit SW STATION CALL and the indication will disappear.
  • If there is no frequency for the station corresponding to the time zone stored in the ROM, a beep sounds, "MEMORY" "EMPTY" appears in the display, and the radio returns to the previous condition.
  • If you press a station button without the ROM in the ROM compartment of the radio, a beep sounds, "NO" "ROM" appears in the display, and the radio returns to the previous condition. If the ROM is displaced when "SW STATION CALL" indication is lit in the display, a beep sounds, "NO" "ROM" appears in the display, and the radio changes to manual tuning.
  • If "NO" "ROM" is displayed with the SW STATION CALL ROM inserted in the ROM compartment, the contact surface of the ROM may be dirty. See "Cleaning the SW STATION CALL ROM contact surface", page 46, and clean the contact surface with a cotton swab. Do not clean the contact springs of the main unit, as they may deform and cause a malfunction.

text_image LOCAL STANDBY 17:04 UTC + 9 TOKYO

To check the standby time

Hold down STANDBY MEMORY a or b with the radio turned off. The preset standby time is displayed while the button is pressed.

To change the standby time

Repeat steps 4 to 6 and preset a new standby time.

To cancel the standby function

Press STANDBY MEMORY a or b with the radio turned off so that "STANDBY" "a" or "b" is cleared from the display.

Make sure to release the button within a second. If the button is pressed for longer than a second, the radio goes to step 5.

At the standby time

The radio turns on, "SLEEP" lights up, and the preset broadcast station is tuned in. The radio turns off after about 60 minutes.

Notes

- The Standby function is activated when the currently displayed time, whether in LOCAL or WORLD display mode, reaches the standby time. Make sure, therefore, that the time display is in the mode of your choice. - If a station was already stored to the STANDBY MEMORY button, the previous preset station is overwritten by the new preset. If the preset label had been edited, it will return to the following default;

$$ \begin{array}{l} \mathbf {a} = \text {STBY - a''} \\ \mathbf {b} = \text {STBY - b''} \end{array} $$

To change labels, see "Editing labels", page 36.

- Make sure that the radio is turned off before setting the standby time. You cannot set the standby time with the radio turned on.

Tips

- To temporarily cancel the Standby function, turn off the radio and slide HOLD in the direction of the arrow so that “○—” is displayed. The standby timer goes back to effect when HOLD is turned off (“○—” is cleared from the display). See “Using the hold function”, page 42.

- Once the standby presets are set, the radio turns on at the preset time everyday unless the standby status is canceled (see “To cancel the standby function”, above). Canceling the standby status does not erase the standby setting itself. The setting can be put back to the standby status by pressing STANDBY MEMORY a or b with the radio turned off so that “STANDBY” “a” or “b” is lit in the display.

- If the standby memory is in standby status, it takes effect even when you are listening to the radio. The radio switches to the preset standby frequency at the standby time.

- You can set both STANDBY memories to the standby status at the same time (i.e., both the a and b indicators are lit in the display). The radio turns on at the first standby time to receive the first standby frequency, then switches to the second standby frequency at the second standby time.

- If both STANDBY memories are set to the same standby time, STANDBY a takes precedence.

To wake up to the buzzer

Tips on radio waves

What is SSB (Single Side Band)?

SSB is very popular among ham and business radio transmissions, and is commonly used in many amateur bands because of its superiority in signal intelligibility. Its impressive signal intelligibility is achieved with minimum interferences when compared to DSB (Double Side Band) owing to its half bandwidth structure.

In general, SSB transmissions employ the USB (Upper Side Band) modulation, while amateur band transmissions below 10 MHz employ the LSB (Lower Side Band) modulation.

Conventional radios without a BFO (Beat Frequency Oscillator) circuit cannot receive SSB transmissions successfully. This unit can receive SSB transmissions successfully with the built-in BFO (Beat Frequency Oscillator) circuit.

SONY ICFSW07 - What is SSB (Single Side Band)? - 1

line | Carrier | Frequency | | ------- | --------- | | LSB | 0 | | USB | 0 |

What is CW (Continuous Wave)?

CW is also popular among ham and business radio transmissions. Unlike other signals, the amplitude of a carrier is not modulated for CW transmissions. CW transmissions convey information by interrupting the carrier and use Morse code as a means of communication.

This unit can receive CW transmissions successfully with the built-in BFO (Beat Frequency Oscillator) circuit as beat sound only. To fully comprehend the information transmitted by CW transmissions, an understanding of the Morse code is prerequisite.

What is synchronous detection?

There are two underlying obstacles in optimum AM reception: distortions due to fading and interferences from adjacent broadcast stations.

Synchronous detection is effective in solving these obstacles.

Distortions due to fading are generally caused by over-modulation which occurs when a carrier component of the received signal is attenuated along the way. The synchronous detection circuit of this unit generates a pure carrier frequency with no level variation which is ideally synchronized with the original carrier to compensate for the attenuated carrier component, thus dramatically reducing distortion.

Likewise, AM (LW, MW, and SW) broadcast generally employs DSB (Double Side Band) signals for transmissions in which the modulated signals are transmitted using both the upper and lower side bands (USB and LSB). In most cases, one of the side bands is affected by interferences from adjacent broadcast stations (i.e., beats). The synchronous detection circuit of this unit extracts one of the two

sides (USB or LSB) of the DSB

(Double Side Band) signal which is free from interferences. This allows clear reception without the interferences from adjacent broadcast stations.
