1. SAFETY

Before applying power

IMPORTANT!

U.S.A. and Canada
Units shipped to the U.S.A. and Canada are designed
for operation on 120 volts AC only. These units are not
equipped with an AC voltage selector switch and the
discussion of such a switch that follows should be
disregarded.

All other countries
Units shipped to countries other than the U.S.A., Cana­da are equipped with an AC voltage selector switch on
the rear panel. Refer to the following paragraph for the
proper setting of this switch.

AC voltage selection

This unit operates on 120 volts, 220 volts or 240 volts
AC. The AC voltage selector switch on the rear panel is
set to the voltage that prevails in the area to which the unit

is shipped. Before connecting the power cord to your AC
outlet, make sure that the setting position of this switch
matches your line voltage. If not, it must be set to your
voltage in accordance with the following direction.



Note:
Our warranty does not cover damage caused by excessive
line voltage due to improper setting of the AC voltage se­lector switch.

Before plugging in this unit, make sure that the position
of the AC voltage selector conforms to your line (mains)
voltage. If not, it must be reset.

NOTCH control

The NOTCH function is used to reduce or eliminate hetero­dyne, or CW type signal interference.

If a single tone such as a CW signal is superimposed on
the receive signal, turn the NOTCH switch ON and slowly
adjust the NOTCH control to eliminate or minimize the

beat signal. Normally the NOTCH point will occur between

11:00 and 1:00.

The NOTCH filter will not be effective against SSB, AM or

FM type signals, only single tone CW type signals.

In the CW mode, an audio peak filter (APF) is automatically

selected; adjust the NOTCH control for the best signal.

In CW, we recommend the use of a CW filter (YK-88C or

YK-88CN). When a CW filter is installed, the APF is dis-

connected.

Whithout a CW filter installed, APF is connected in CW

mode. The APF works in similar fashion as a CW filter.

The IF SHIFT control allows you to shift the IF passband of
the receiver, without changing the actual center frequency
of the receiver. This control is useful when there is inter­ference near your center frequency.

Interference from lower frequencies can be reduced or eli­minated by rotating the IF SHIFT control clockwise. This
will cause the resulting audio frequencies to have a slightly
treble response, i.e. low cut filter (low frequencies atten­uated). Interference from higher frequencies can be re­duced or eliminated by rotating the IF SHIFT control

counterclockwise. This will cause the resulting audio frequen­cies to sound a little bassy, i.e. high cut filter (high frequen­cies attenuated).

Note:
The IF SHIFT control does not function in the AM or FM
modes.

RF gain control

This control adjusts the gain of the receiver high-

frequency amplifier section.

For normal receiver pe
control should be in the full clockwise position. If you are
having trouble copying the desired signal make a note of
the stations peak S-meter reading. Then, adjust the RF
control counterclockwise, so that the meter needle is sta­tionary at this level. Now, all signals that were less than
the desired signal will be attenuated, such as static noise,
etc., making reception easier.
If the incoming signal pegs the S-meter you can also re­duce the receiver gain by counterclockwise rotation of the
RF control. The S-meter pointer will always advance up­scale as the RF control is rotated counterclockwise, as a
visual reminder that the gain of the radio has been re­duced.

Simultaneous use of the RF gain control and AGC
switch

If a strong signal (such as a local station) appears in the vi­cinity of the intended receive signal, the S-meter may
show unusual deflection due to the AGC voltage deve­loped from the strong disturbing signal. If this occurs, turn
the RF gain control counterclockwise so the meter pointer
remains at about the original deflection peak and turn the
AGC switch to the FAST position. This will reduce the un­wanted AGC voltage and permit clear reception.

4-2-1. Microprocessor back-up battery
The R-5000 has a rechargeable back-up battery which is

charged automatically while the AC power cable is con­nected to an AC outlet. It takes about 6 hours to recharge
a deeply discharged battery using the AC power cable. If
you suspect the battery is not charged when you purchase
the R-5000 or the radio performs erratically, perform the
"A = B (reset)" procedure described in section 4-2-2. The
battery will last about 10 days with the AC power cable
disconnected.

4-2-2. Microprocessor reset
When the microprocessor has functioned erroneously or
when installing the transceiver, switch on the power with
the A = B key pressed.

Note:

4-2-6. Frequency step

The frequency step is set automatically depending on

1.
the mode that has been selected. Different steps can
be set by using the STEP key. The relationship bet­ween mode and step is shown below.

The step size in which frequencies are changed by the
TUNING knob can be changed by the MODE key and/or
the STEP key.

Frequency Step

When a 10 Hz or 100 Hz frequency step is selected ra-

pid tuning is possible by rotaing the TUNING knob
quickly.
When the TUNING knob is rotated at about 3 revolu­tions a second a geometric increase in the tuning step

occurs, that corresponds to the speed of dial rotation.
This geometric increase occurs in 10 Hz steps in the

2.
LSB, USB, CW, or FSK mode and with the STEP key
OFF and in 100 Hz steps in the LSB, USB, CW, FSK,

AM, and with the STEP key ON.

4-2-7. Dual digital VFO's
Operational convenience can be enhanced thru the use of
both VFO A and VFO B.
Two VFO's are provided to allow you to change frequen­cies rapidly. You could set one VFO to the lower tuning

range and the other VFO to the upper tuning limit. You'
can set either VFO to any frequency you desire.
When the VC-20 VHF Converter Unit is installed you will

have 4 effective VFO's. VFO A and VFO B for HF and VFO
A and VFO B for VHF.

(a) A = B key

Depressing this key causes the data contained in the
inactive VFO (the VFO that is not currently being dis­played) to change to the same data contained in the
active VFO (the one currently displayed). Both the fre­quency, mode and antenna selection are changed.

For example:
VFO A is set at 7 MHz in LSB, and VFO B is 21 MHz in
USB. VFO A is the active VFO (show on the display).

Depressing the A = B key will cause VFO B to change
to 7 MHz

in

LSB.
In the HF position, the A = B key matches HF VFO A to
HF VFO B; in the VHF position, it matches VHF VFO A

to VHF VFO B.

Note:


Data can not be transferred between HF and VHF
bands.

(b) A/B key

Allows selection of the desired active VFO. Each time

this key is depressed the active VFO will alternate bet­ween VFO A and VFO B.
In the HF position, the A/B key functions on the HF
VFO's only; in the VHF position, it functions on the
VHF VFO's only.

4-2-8. Direct keyboard frequency entry

Direct keyboard entry of the frequency is possible using
the Numeric Keypad on the R-5000. This allows rapid
changes in frequency without the delays encountered
when using other tuning methods.

1.

Select the VFO mode.

2.

Press the ENT key. The display will indicate.

Enter the desired operating frequency from Most Signi-

3.
ficant Digit to the Least Significant Digit. You do not

have to enter trailing zeros, but you must enter leading

zeros. (03.500.00MHz).

4.

After the least digit has been entered press the ENT key
again to signify you want the radio to change fre­quency. If you entered the frequency down to the near­est 10 Hz a beep will sound and the radio will automati­cally change to the new frequency without the need of
pressing the ENT key for the second time.

For example:

To enter 14.200.00 MHz there are two methods:

Method one: Press [ENT], [1], [4], [2], [ENT].
Method two: [ENT], [1], [4], [2], [0], [0], [0], [0].

Note:



Attempting to enter a frequency outside the tuning

range of the radio will cause the display to return to the

frequency of operation that was in use before the ENT

key was pressed.

5.

If you make a mistake while entering the frequency and
have not yet pressed the ENT key, or entered the final

digit, you may cancel the input by pressing the CLEAR

key.

6.

To the display shown before the ENT key was pressed.

For the VHF range, a "1" (corresponding to 100 MHz) is

4-3. MEMORY

The R-5000 incorporates a convenient 100 channel me­mory that can be used to store and recall commonly used
frequencies. These channels can be subdivided into 10
user-defined groups to tailor the R-5000 for optimum
operation in a particular application. You can, for instance,
assign channels 10 through 19 to the 160 meter band,
channels 20 through 29 to the 80 meter band, channels
30 through 39 to the 40 meter band (LSB), channels 40
through 49 to the 20 meter band (USB), channels 50
through 59 to the 15 meter band, channels 60 to 69 to
the 10 meter band (FM), channels 70 through 79 to the 12
meter band, and channels 80 through 89 to various shor­twave bands. After completing channel assignments, you
can then use the memory scan function to automatically
recall the stored frequencies on a group basis.

HF or VHF frequencies can be stored in any memory loca-

tion.

4-3-1. Memory entry

1. With the R-5000 in the VFO mode, select the desired
operating frequency, mode and antenna number as de­scribed in previous sections.

Note:


If you decide not to enter the information into memory
press the CLEAR key to return to the original frequency,
mode and antenna.

4-3-2. Memory Channel Recall

Fixed channel type recall is possible when using the
VFO/M key to recall memory channel information. The
stored frequency cannot be changed.
The following procedure shows how to recall a channel.

1.

During VFO operation, press the VFO/M key to initiate
Memory Channel operation. This causes the Memory
Channel to return to the status (antenna number, mode,
and frequency) prior to the Memory Channel operation.

The VFO selected (A or B) before changing to the Me-

mory Channel operation will be displayed.
Example:

When 14.175 MHz is stored in Memory Channel 23.

2. Press the M.IN key. The radio will enter the Memory
Scroll (M.SCR) mode. The current memory channel
number (M.CH), frequency, mode and antenna will be
displayed, but the actual operating frequency and mode

will remain unchanged allowing uninterrupted recep­tion.

3. Select the desired memory channel using one of the

three methods described below.
(1) Turn the TUNING knob until the desired channel

number is displayed (One revolution of the knob
cover about 20 channels.)

(2)

Enter a two digit channel number using the Numer­ic Keypad, being sure to include the leading zero for
channels 00 through 09. Pressing the CLEAR key
before pressing the second digit will return you to

the original channel.

(3)

Use the UP/DOWN keys to scroll thru the different

memory positions.

4. When the desired memory channel is found and dis­played, press the M.IN key again. The current fre­quency, mode and antenna number will be stored, the
Memory Scroll mode will be cancelled, and the R-5000

will return to the operating mode and frequency that
was displayed before the M.IN key was pressed initially.

2.

Select a Memory Channel by using the TUNING knob,
Keypad, or MHz (UP/DOWN) switch.
Example:

When Memory Channel 68 (28.800 MHz) is selected.

3.

If you press the VFO/M key again, the original VFO

operating information will be restored.

Note:



The only way to tune is to transfer the data to the VFO.

4-3-3. Clearing a Memory Channel

Data may be erased by depressing the ENT key while de­pressing the CLEAR key.
A Memory Channel may be cleared by the following proce­dure.

1.

Enter the Memory Channel mode by pressing the
VFO/M key.

2.

Select the channel number that you want to clear using
any of the methods previously described.
Press and hold the CLEAR key.

3.

4.

Press the ENT key. Then release both keys. The radio

will beep. The display will blank and no sound will

come from the speaker.
You may now return to the VFO mode by pressing the
VFO/M key.

4-3-4. Memory Channel Scroll
The following procedure provides a method to check a

Memory Channel Frequency without changing or loosing

the current receive frequency.

21

During Memory Channel operation, press the VFO/M

1.
key to change to select VFO operation.

Press the M IN key once to initiate memory Scroll. The

2.
M.SCR indicator lights, and the memory Channel Fre-

quency is displayed. (Although the displayed frequency
will change, actual reception will be at the previous fre­quency (that is, the frequency before the M IN key is

pressed) of the VFO.) Memory shifting can also be

done by pressing the M>V key.

Select a Memory Channel using the TUNING knob, Nu-

3.
meric Keypoad, or MHz (UP/DOWN) key. The fre-

quency stored in the Memory Channel will be displayed.



Note:
Mode and antenna number data are not displayed.

To clear Memory Scroll operation, press the CLEAR key

4.

or the M IN key again to restore Memory Channel oper­ation.

4-3-5. Transferring memory information to the VFO.
The following procedure transfers the contents of the Me-

mory Channel to the VFO.

In the VFO mode, press the VFO/M key to set the Me-

1.
mory Channel mode. This returns the Memory Channel

to the status (antenna number, and frequency) prior to
the VFO operation. The VFO selected (A or B) before

setting the Memory Channel mode is displayed. To
transfer the memory contents to a VFO which is not
currently operating, press the A/B key before pressing
the VFO/M key, in order to switch to the desired VFO.
Example:

When 14.175 MHz is stored in Memory Channel 23.

Note:


Contents of a Memory Channel can be transferred to the
VFO without regard to HF or VHF operation.

Notes:



Data in the VFO is replaed by the memory data. me-

1.
mory data is not lost during this operation.
In the Memory Scroll mode (M. SCR LED is lit), memory

2.
channel information can also be transferred to the VFO.

Select the desired memory Channel by using the TUN-

2.
ING knob, Numeric Keypad, or MHz (UP/DOWN) key.
Example:
Memory Channel 16 containing 21.225 MHz is select­ed.

Press the M>V key. The contents of the Memory
Channel will be transferred to the VFO and operation
changes to the VFO mode.

Notes:

When the M>V key is pressed, the contents of the VFO

are cleared but the contents of the Memory Channel

will not be cleared.

If nothing is stored in the selected Memory Channel,
only the channel number is displayed; no transfer is
carried out.

Example:
Frequency (21.225 MHz) is transferred to the VFO.

When the TUNING knob is turned, the frequency

changes from this new frequency.

the Numeric keypad are pressed in that sequence.

4.

To resume scan, press the SCAN key again.

5.

To clear scanning, press the CLEAR key.

Note:


The R-5000 microprocessor remembers the various scan
parameters that you have specified and will follow what­ever you have entered the next time you press the SCAN
key.

Example:
Previously programmed memory scan data was to scan
Memory Channels 20-29 and 40-49.

To scan this same range again simply press the SCAN

key.

The R-5000 will continue to execute scan according to the
above parameter until you manually change the informa­tion. This saves a lot of key strokes if you always scan the
same ranges, etc.

4-4-2. Program scan

In the program scan mode the R-5000 will scan from
channel 8 to channel 9 of the current memory channel
group. This allows you to program up to 10 different scan

ranges; 18 — 19, 28 — 29, 38 — 39.... The program scan

step size is determined by the mode in channel 8 and the

STEP key. To specify which group to scan press the M. IN
key to enter the Memory Scroll mode. Select the desired
memory channel group using any desired method, you can

select any memory channel of the desired group. After the
group has been specified press the CLEAR key to return to
the VFO mode. Scan will begin at the frequency specified

in memory X 8 and proceed up or down, depending on the

frequency entered into channel X 9. Scan will go up if the
frequency in X 9 is greater than X 8 and down if channel X
9 is less than X 8.

Note:


All scanning groups (0 to 9) are selected upon shipment
from out factory and when the microprocessor is reset.

3. When you release the SCAN key, scanning starts.

Notes:

1. If no valid memory channel exists in a selected group,



scanning will be automatically reset and memory chan­nel restarts. A valid memory channel is one channel
which is not locked out and in which a frequency is
stored.

2.

When the AM or FM mode key is selected, the R-5000 will

stop on a busy channel during scan operations. When an
incoming signal is detected during frequency scanning the
BUSY indicator will light. In order for this function to oper­ate the SQL control must be adjusted to the threshold
point. The R-5000 will remain on a station approximately

5 seconds and then resume Time Operated scan.

Note:
All modes other than AM and FM do not stop on a busy

channel.

7-1. ENJOYING SW RECEPTION

ENJOYING SW RECEPTION
Every country in the world has broadcast stations, and
most countries have Amateur radio stations. The earth is
virtually surrounded by innumerable radio waves, provid­ing us with information and news. Your receiver inter­cepts many of these transmissions.

Radio waves cover a wide range of frequencies including
long-wave (LF), medium-wave (MF), and short-wave (SW)
or high frequency (HF). Since short-wave signals travel
around the earth, it is fun receiving exciting news and exo-

Propagation of Radio Waves By the Ionosphere
The earth is surrounded by the atmosphere. The atmos-

pheric molecules existing between 50 km and 500 km
above the earth collide with ultraviolet rays and electrons

emitted from the sun, and a layer of electrons and ions is
formed. This layer is called the ionosphere and it has a

characteristic of refracting radio waves. Radio waves

emitted from the antenna of a transmitter can be classified

as surface waves and ionospheric waves. Surface waves

travel along the earth directly, and are used mainly for me-

dium frequency AM broadcast and TV and FM broadcast.

Ionospheric (sky) waves travel a long distance because

they are refracted repeatedly between the ionized layer

and the earth. As short-wave broadcasts propagate by

ionospheric waves, their signals often reach around the

earth. The surface wave tends to weaken at HF and short-

wave frequencies and therefore travel only a short dis-

tance, while ionopheric waves persist as the frequency in-

creases (up to a certain point, determined by ionization in-

tensity) and travel long distance with little path loss. Ultra

high frequencies pass through the ionized layer, and thus
the service area is limited to a short distance from the an­tenna. The ionosphere is divided into three layers, D, E and

F.
The electron density in the layer is increased in steps ac­cording to the distance from the sun. High frequency
waves are refracted by the F layer and travel a long dis­tance.
The state of the ionized layer is closely associated with the

relative positions of the sun and the earth and also with
the activity of the sun. The D and E layers almost disap-

pear at night, while the F layer changes in height and den­sity depending on daytime or night time, and changes the
upper frequency limit to be reflected. Occasionally,
"clouds" of ions will drift through the E layer, causing
strong signal propagation (called "sporadic E propaga-

tic music from overseas broadcast stations or transmis­sions from Amateur radio stations and various industrial,

marine, government, and military. It is also interesting to
collect reception or verification (QSL) cards. To ensure
maximum enjoyment of short-wave signals - how the sig­nals travel around the earth, the method of receiving sig­nals most effectively, the method of identifying the
country broadcasting programs, etc.

tion") over several hundered miles, usually between 15
MHz and 30 MHz, and sometimes higher in frequency.
Such a phenomenon also occurs with changes in seasons
or rotation cycle of the sun as well as unusual activities of
the sun (change in the sunspot cycle every 11 years, unex­pected explosion on the sun, etc.). To cope with this, inter­national short-wave broadcast stations change their fre­quencies according to seasons or directions of radio
waves, or use different frequencies at the same time for
broadcasting the same program.

Frequency Distribution in the Broadcast and Amateur
Bands.

The R-5000 receiver covers from 100 kHz to 30 MHz, to

receive international broadcast and communication ser­vices.
As shown in the Frequency Allocation Chart, broadcast
and Amateur radio station frequencies are allocated in

specific bands expressed in megaherts (MHz) or wave-

length in meters (m). Also in the chart, the frequencies of

"other stations" are assigned for fixed station business

use, marine mobile, aviation mobile, land mobile, radio bea-

con stations, etc. The following relationship exists bet-

ween frequency and wave length.

RADIO FREQUENCY ALLOCATION

As will be seen from this relationship, the 31 m band and

9 MHz band, for example, are the same shortwave broad­cast band, covering the range of 9,500 kHz to 9,775 kHz.

7-2. ANTENNA AND GROUNDING

7-2-1. Antenna
The following describes various antenna types and their
installation.

Long Wire Antenna

•
This is the simplest antenna, using about 30 – 100 feet
(10 – 30 m) of wire installed between poles, trees or
other convenient supports. The antenna wire should be
heavy 8 gauge vinyl insulated, stranded wire or 4-gauge
copper wire or copperweld. This type of antenna must be
installed horizontally to a length of 60 feet (20 m) or more,
and be positioned as high as possible. Note that it should
be as far away as possible from AC power lines, buildings,
trees and other objects.
Fig. 7-1 shows an inverted L antenna. Other antenna
types such as sloping, vertical, etc. are also possible.
A long-wire antenna, when installed in an open area, is sui­table for all-band operation.

•

Inverted V Antenna
This is a modified doublet antenna, designed to be in­stalled on a single pole or support. The characteristics of
this antenna are almost the same as those of a doublet.
The overall length
and is computed thus:

Multiband Antenna

•
This antenna uses more than one doublet for multiband re­ception. The overall length
doublet. If the lengths L1, L2 and L3 are cut for 7 MHz, 14

MHz and 28 MHz, then L1 is tuned to 21 MHz (3 x 7 MHz),
permitting reception on 4 amateur bands 7 – 28 MHz.

When used only for reception, this antenna will cover the

6 – 30 MHz SW bands. (See Fig. 7-4)

is a little more than that of a doublet,

"L"

is the same as that of the

Doublet Antenna

•
This type of antenna is suitable for reception of a specific

band.
The relation between the overall length
frequency is:

This antenna is directional. Signal strength is maximum
when the antenna is at a right-angle (broad-side) to the de­sired signal and the frequency for which the antenna is
cut. It must be used with a 75-ohm coaxial feeder. (See

Fig. 7-2)

•

Trap Vertical Antenna

Antennas designed exclusively for BCL are available com-

mercially, or may be built yourself. Antennas designed for
HAM band (3.5 . 28 MHz or 7 – 14 MHz) operation will

provide satisfactory broadcast reception for stations near
the SW bands. Antennas of this type are most suitable for
the listener who does not have enough space for installa­tion of a doublet or long-wire antenna. (See Fig. 7-5)

32

• Yagi Antenna
The Yagi antenna is best suited for reception in a specific
band. This antenna features excellent directivity; it pro­vides high gain and minimizes interference when properly
installed. Yagi antennas commercially available are de­signed only for HAM band reception. For SW reception, it

be necessary for you to construct such antennas your-

Discone and log-periodic antennas can cover a wide fre-

quency range. The discone antenna is omnidirectional and

7-2-2. Grounding
Normally, the receiver will operate without being ground­ed. However, a good earth ground improves the efficiency
of antennas such as a long-wire. It also eliminates induc­tive noise and protects the operator from electric shocks

through the AC lines.
To ground the receiver, use a copper or brass plate (or net
or rod) connected to a copper wire, and bury it in the
ground about 1 , 7 feet (0.3 ~ 2 m) deep. A copper
water pipe (not plastic) may also be used. Never use a gas

pipe for grounding.
If the receiver cannot be grounded well, the conterpoise
(antenna radial) would be acceptable.

Note:



Antennas designed for HAM BAND will generally provide

satisfactory reception for SW stations near the HAM
BANDS. For antenna construction details, see the ARRL
ANTENNA HANDBOOK, or similar publications.
