1) Reading the Operating Frequency
The R-1000 Digital Display accurately indicates fre-
quency.
Refer to Fig. 3-2.

2) Setting the Frequency
The BAND switch dial is calibrated at 1 MHz intervals
from 0 to 29. Fig. 3-3 shows the dial set to 9 MHz.

Main Dial
The main dial is interlocked with the main tuning knob. lt
is calibrated at 10 kHz intervals from 0 to 1.000 kHz.
NOTE:
1. When receiving a signal below 200 kHz. the receiver
performance might be deteriorated.
2. When the receiver frequency is set to 0 mMHz OOOkHz.
the S-meter will deflect to the end. (This does not in-
dicate a trouble.)
3.2 MODE SWITCH
When receiving strong local signals. set this switch to AM
WI DE.
This enhances reception with little interference.
providing excellent tone quality.
When unwanted signals are present near the received fre-
quency. set the switch to AM NARROW. This narrows the
bandwidth, reducing radio interference.
6
For reception of SSB, press the USB or LSB/CW button
according to international practice.
For reception of CW signals, press the LSB/CW button.
3.3 RF ATT SWITCH
lf excessively strong nearby stations or high-power night
broadcasts are present within the band being received. a
desired signal may be blocked by receiver desensitization.
Also, if a signal is very strong, the meter may deflect off-
scale. Set the RF ATT switch to an appropriate position. 20
dB (1/10). 40 dB (1/100) or 60 dB (1/1000). At the 0 dB
(1/1) position, the signal is not affected.
3.4 NB SWITCH
For pulse type noise. such as generated by automobile igni-
tion systems. turn the NB switch ON. The noise will be
reduced or eliminated.
3.5 DIMMER SWITCH
By pressing thes switch. the light intensity of the digital dis-
play, meter and the main dial will be reduced.
Use this feature when the receiver is operated in the dark. as
it reduces eye-strain.
Practical Operating Procedure
Radio stations throughout the world are listed in the
WORLD RADIO TV HANDBOOK or similar publication.
Radios frequency allocations are listed on page 12 of this
manual.
Example
1.
Reception of MW (Medium Wave) stations.
a. Connect the supplied wire antenna or a long wire anten-
na to the MW ANT terminal (25).
b. Strang signals can be received clearly without being
grounded.
However, a good earth ground is recom-
mended for weak signals.
lf an earth ground is not available. a counterpoise
(antenna radial) would be acceptable.
c. Set the MODE switch to AM WIDE.
d. Set the BAND switch (24) to 0 or 1 and tune in the desi-
red station.
e. lf necessary, use the RF ATT switch(12),the NB switch
(17). and the TONE control (11).
f.
lf the audio outputis not clear because of interference.
set the MODE switch to AM NARROW (21 ).
Example II.
Reception of SW (Short Wave) and LW
(Long Wave) stations.
The SW and LW allocations vary throughout the world. (See
page 12)
1.
For LW Reception.
Follow the procedures of Example
1.
2.
For SW Reception
a. lf the supplied wire antenna or a long wire antenna is
used. connect it to the SW B terminal (27)and set the
SW ANT SELECT switch (33) to the SW B position.
