Other bands used by Amateur radio operators (HAMS)
are displayed when in SSB mode of operation. The
Amateur Band Designators and corresponding fre-
quency ranges are as follows.
Amateur Band Designators
80 METER: 3500 - 4000 kHz
40 METER: 7000 - 7300 kHz
30 METER: 10,100 - 10,150 kHz
20 METER: 14,000 - 14,350 kHz
17 METER: 18,068 - 18,168 kHz
15 METER: 21,000 - 21,450 kHz
12 METER: 24,890 - 24,990 kHz
10 METER: 28,000 - 29,700 kHz
AM SYNCHRONOUS OPERATION
For general tuning and listening, normal AM is best. If,
however, the received signal sounds distorted, or
interference from adjacent stations is present, AM
synchronous should be engaged. The synchronous
detector in your receiver can greatly reduce the severe
audio distortion that can occur due to selective signal
fading. The synchronous detector also permits
selectable tuning to either the upper or lower sideband
portion of an AM signal. Since most all AM (LW, MW
and SW) broadcasting generally uses double-sideband
transmission, synchronous detection of either of the
two sidebands results in full reception of the transmit-
ted information. The selectable sideband tuning and
synchronous detection not only aids reception by
permitting tuning to the stronger or less distorted
sideband, but also permits rejection of the sideband
nearer to the interfering signal(s). For Example:
The synchronous detector will lock to the strongest
signal that is within the IF passband when it is activated.
Most of the time, the strongest signal will be the carrier
of the desired signal. First, be sure the main tuning is
set to within 1 kHz of the desired stations transmitting
frequency. Press the
AM
SYNC
button to activate synchro-
nous operation. If adjacent channel interference or
any other undesired signal is sufficiently strong, the
synchronous detector may lock to it instead. In that
case, press the
AM
SYNC
button to turn the synchronous
detector off and repeat the tuning process.

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 accom-
plished 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.
Pressing and holding the / buttons will cause the
tuning rate to increase after a short period of time.
SHORTWAVE METER BAND DESIGNATOR
ENTRY
To facilitate tuning to particular sections of the short-
wave band that contain many worldwide broadcasts of
news, information and music, the SW2 displays the
METER band if the receiver is tuned to a frequency
that is contained by designated shortwave bands. If the
receiver enters one of the 'METER BANDS', the
number of that band will be displayed on the right side
of the display, above the 'METER' LED. In some cases,
the worldwide broadcast station may not announce its
exact operating frequency, but will announce the
METER band in which it is operating or to which band
it will move to improve worldwide reception at a
particular time of day. The Shortwave Band Designa-
tors and corresponding frequency ranges are as
follows:
Shortwave Band Designators
120 METER: 2300 - 2500 kHz
90 METER: 3200 - 3400 kHz
75 METER: 3900 - 4000 kHz
60 METER: 4750 - 5060 kHz
49 METER: 5800 - 6200 kHz
41 METER: 7100 - 7600 kHz
31 METER: 9500 - 9900 kHz
25 METER: 11600 - 12100 kHz
22 METER: 13570 - 13870 kHz
19 METER: 15100 - 15800 kHz
16 METER: 17480 - 17900 kHz
13 METER: 21450 - 21850 kHz
11 METER: 25600 - 26100 kHz
