TUNING SSB STATIONS

SSB (single sideband) is very popular
among amateur radio and business ra-
dio users because of its superior signal
quality. Many amateurs who operate
SSB and transmit below 10 MHz gen-
erally use LSB (lower sideband), while
amateur and commercial stations who
transmit above 10 MHz generally use
USB (upper sideband). Your receiver
receives both USB and LSB transmis-
sions.
Follow these steps to receive SSB
stations.
1. Select an SW band (see "Select-
ing a Band" on Page 18).
2. If you know the frequency of an
SSB station, enter that frequency.
Or, scan the band for SSB stations
by slowly rotating
, tuning through the selected
ING
band until you hear an SSB sta-
tion. Or, scan the band for USB or
LSB stations by holding down

USING RDS

The receiver displays information
about FM radio stations that transmit a
Radio Data System (RDS) signal.
When the receiver receives an RDS
MANUAL TUN-
station, the station's call letters appear
on the display. Also, if the station
broadcasts CT (clock time) informa-
tion, the receiver automatically cor-
rects the displayed time.
for
Note: SSB stations sound dis-
torted 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 transmit-
ted with a suppressed carrier, the
signal strength indicator will move
more quickly when there is a
transmission and more slowly dur-
