Installation, continued RANDOM LENGTH WIRE ANTENNA INSTALLATION For general broadcast and shortwave listening, an outside random-length wire antenna can be used. Figure 3 shows a typical random-length wire antenna installation. The length of the wire may be from 30 to 100 feet. Attach and solder the lead-in to one end of the antenna. Connect the other end of the lead-in wire to the 50Ω screw terminal on the rear panel of your receiver.
6 Getting Started SW2 Shortwave Receiver MEM + 60 + 40 + 20 S9 AM SYNC LSB USB METER POWER RF GAIN VFO TUNING kHz 1 2 3 MEM 4 5 6 AM SYNC 7 8 9 SSB 0 CLEAR VOLUME RF GAIN VOLUME NUMERIC KEYPAD POWER TUNING BUTTONS TUNING WHEEL FIGURE 4 GENERAL OPERATING INFORMATION This receiver is easy to use. Please take a few moments to read through this section and familiarize yourself with general operating information. GETTING STARTED 1.
Getting Started, continued Example 2: 29660 kHz Press 2 , 9 , 6 , ** 6 , 0 ** When the maximum of 5 digits are entered, the receiver will automatically enter the frequency as soon as the last digit is pressed. TUNING BUTTONS and TUNING WHEEL Tuning to a desired frequency can also be accomplished by pressing the / Tuning buttons and/or turning the Tuning wheel. The frequency will change in 5 kHz increments with the / Tuning buttons, and will change in 50 Hz increments when turning the Tuning wheel.
8 Getting Started, continued AM SYNCHRONOUS OPERATION, continued If interference is present, press the SSB button to select the sideband with the least interference. When AM/SYNC has been activated, moving the main tuning knob will cause the SYNC circuit to momentarily disengage (indicated by SYNC flashing), then back on again when tuning has stopped. AM SYNC will not operate properly on intermittent transmissions such as those encountered on CB radio bands, for example.
Memory Functions This receiver contains 100 memories (00-99) that can be used to store and recall commonly monitored frequencies. The following operating parameters are also stored with any memory channel: 1) Frequency 2) Mode 3) Synchronous Detector NOTE: Some of the 100 memory channels are factory programmed to help the user get started.
10 Troubleshooting TROUBLESHOOTING PROBLEM PROBABLE CAUSE SOLUTION No front panel display A) No power applied either by AC Adaptor or DC source. A) Check that AC Adaptor cable or DC cable is properly connected to the rear panel POWER INPUT connector. Check that the AC Adaptor is plugged into a source of nominal 120 VAC power source. B) Check the AC Adaptor and replace if defective. Check DC power source, fuse and cable. C) Press the button for a frequency display.
