[. . . ] In the longwave (LW) band, you can hear ship-to-shore calls, other marine and aeronautical services, and sometimes even hurricane reports. You can also tune to local broadcasts in the FM and medium-wave (MW) bands. (In the United States, we commonly call the MW band the AM band. ) In addition, you can connect a cassette recorder to the receiver's record line out and standby jacks so you can directly record your favorite programs live or at a preset time. Your receiver's features include: Digital Synthesized Radio -- ensures accurate, stable tuning. [. . . ] The receiver scans up or down the selected band and tunes to the first 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 or to scan the band. Direct Access Tuning Follow these steps if you know a station's frequency and want to directly tune to that station. 19 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. memory locations. See "Storing SW Frequencies in Memory" on Page 28 for more information. · International commercial broadcast programs (often in English) usually contain news, commentaries, music, and special features reflecting the culture of the broadcasting country. Reception for this range is best between 6:00 PM and midnight (your time). Follow these steps to tune preprogrammed shortwave stations. Find the country and frequency for the shortwave station you want to tune in the "DX-440 Shortwave Pages Chart" on Page 21. Then write down the page number and memory location number shown on the chart for that station. Select an SW band (see "Selecting a Band" on Page 18). 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 or TUNING 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. 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). 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. 25 Follow these steps to use RDS.
