Receiving Single Side Band/Continuous Wave Transmissions

1. Turn on the radio, and select AM with FM/AM.
2. Set AM MODE to SSB.
3. Switch LSB/USB to select the desired sideband. To receive CW, select LSB.
4. Tune in a frequency near the broadcast you want to receive by way of direct tuning (see "Direct Tuning"), manual tuning (see "Manual Tuning") or scan tuning (see "Scan Tuning").
5. Adjust the tuning with SSB FINE TUNE.
   You can adjust the frequency within an approx. ±1.5 kHz range.
   The frequency display will not change.

What is SSB (Single Side Band)?
SSB is very popular among ham and business radio users and will be found on all of the amateur bands because of its signal intelligibility.
In general, SSB transmissions employ USB (upper sideband) modulation, and for amateur bands lower than 10 MHz, LSB (lower sideband) is often used.

What is CW (Continuous Wave)?
CW is also popular among ham and business radio users. In CW transmission, the amplitude of a carrier is not modulated while that of other system is modulated. CW conveys information by interrupting a carrier using Morse code. It can be heard as a beat sound only with the unit equipped with BFO circuits. To understand the information transmitted by CW, you need to learn the Morse code.

Receiving with the Synchronous Detection

1. Turn on the radio, and select AM with FM/AM.
2. Tune in a frequency you want to receive by way of direct tuning (see "Direct Tuning"), manual tuning (see "Manual Tuning"), scan tuning (see "Scan Tuning") or preset tuning (see "Preset Tuning").
3. Set AM MODE to SYNC.
4. Switch LSB/USB to a sideband that gives clear reception.
   When the synchronous detection is locked, the SYNC LOCK indicator lights.

What is synchronous detection?
There are two big problems in AM reception: distortion due to fading and interference from adjacent stations. Synchronous detection is effective in solving these problems. Distortion due to fading is caused by over-modulation, which occurs when a carrier component of the received signal is attenuated on the way. In this receiver, a pure carrier frequency with no level variation, perfectly synchronized with the original carrier, is generated in the synchronous detector circuit and is mixed with the received signal to compensate the attenuated carrier component. In this way, distortion is remarkably reduced. On the other hand, AM (SW, MW, and LW) broadcasting generally uses double sideband transmission, in which modulated signals are transmitted using both the upper and lower sidebands (USB and LSB). In most cases, one of the sidebands is affected by interference from adjacent stations (beats). In the synchronous detector circuit, one of USB and LSB can be received. This allows dear reception without interference from adjacent stations.

Using the Standby Function

1. Tune in the desired station which you want to listen to at the desired time by way of direct tuning (see "Direct Tuning"), manual tuning (see "Manual Tuning"), scan tuning (see "Scan Tuning") or preset tuning (see "Preset Tuning").

For Better Reception

Using the Supplied SW Antenna

Usually the telescopic antenna is sufficient for SW reception. However, in a metal or concrete building, the use of the supplied SW antenna is recommended.

To Use the Compact Antenna AN-71 Supplied With the ICF-SW7600G

1. Fully pull out the cord from the case.
2. Attach the coupler to the telescopic antenna.
3. When the window can be opened: Extend the cord and the case out through the window, after making sure there is no danger.
   When the window cannot be opened: Fully extend the cord along the frame of the window.

To Use the Active Antenna AN-LP1 Supplied With the ICF-SW7600GS
Refer to the instruction manual supplied with the AN-LP1.

Using the External FM Antenna

(not supplied)
In a steel-frame building, a mountainous area, at a distance from the transmitter or in a location where ignition noise is severe, FM reception may be unsatisfactory with the telescopic antenna. In this case, connect a commercially available external FM antenna with a 75-ohm coaxial cable.

After use

Using the Wide Range Antenna

(not supplied)
Use the wide range antenna AN-1 or AN-102 (not supplied). There are the following two methods.

Method A (For SW reception)
With a connecting cord, connect the OUTPUT jack of the antenna controller (supplied with the AN-1 or AN-102) and the EXT ANT jack of this unit.

Method B (For MW/LW reception only)

1. With the connecting cord, connect the OUTPUT jack of the antenna controller and the INPUT jack of the antenna coupler (supplied with the AN-1 or AN-102).
2. Position the antenna coupler near the unit.

Example: When the AN-1 is used.

Notes

• When receiving MW or LW broadcasts without the external antenna, be sure to disconnect an SW external antenna.
  Otherwise, you cannot receive them as the built-in ferrite bar antenna does not function.
• If there is lightning, do not touch the wire of an external antenna and disconnect its AC power adaptor (if connected) immediately. Never touch the antenna wire during a lightning storm.
• When using an external antenna, retract the telescopic antenna.
• Locate the outdoor antenna as far away from the street as possible.
• For details about the external antenna, refer to its instruction manual.

• Use the unit within a temperature range of 0°C to 40°C (32°F to 104°F). If it is used in temperatures outside this range, an irregular display may appear on the display window. If it is used in temperatures lower than this range, the display may change very slowly. These irregularities will disappear and there will be no damage to the unit when the unit is used in its recommended temperature range.
• Do not leave the unit near heat sources, such as radiators or air ducts, or in a place subject to direct sunlight, excessive dust, moisture, rain, mechanical vibration or shock.
• Should any solid object or liquid fall into the unit, remove the batteries, and have the unit checked by qualified personnel before operating it any further.
• Since a strong magnet is used for the speaker, keep personal credit cards using magnetic coding or spring-wound watches away from the unit to prevent them from possible damage caused by the magnet.
• When the casing becomes soiled, dean it with a soft dry cloth dampened with mild detergent solution. Never use abrasive cleansers or chemical solvents, as they may mar the casing.
• When there is lightning and you are using an external antenna, immediately disconnect the AC power adaptor (if connected) from the wall outlet. Never touch the antenna wire when there is a lightning storm.
• Never connect a ground wire to a gas pipe.
• Reception of 3.6 MHz may be difficult because of internal spurious signals generated by the built-in oscilators.
• In vehicles or buildings, radio reception may be difficult or noisy. Try listening near a window.
