Dimmer
Adjusting AF Gain
Below are steps to adjust the brightness of the screen and LED.
Below are the steps to adjust the volume so that sound can be
heard from the speaker.
Turn the [AF] control.
Switching the Brightness Level
The preset brightness of the screen and LED can be adjusted
according to the surrounding conditions.
1 Press [MENU].
2 Press F [DIMMER].
Pressing F [DIMMER] each time switches the dimmer setting
in the following sequence: “DIMMER 1” → “DIMMER 2” →
“DIMMER 3” → “DIMMER 4”.
Adjusting the Dimmer Level
The preset values for “Dimmer 1”, “Dimmer 2”, “Dimmer 3” and
“Dimmer 4” can be configured to a different value for Display
(screen) and LED respectively.
1 Press and hold F [DIMMER].
The Dimmer configuration screen appears.
Turning the control to the right raises the volume, while turning
to the left lowers it.
• If no sound is heard or if only a light noise-like sound is heard
even when the [AF] control is turned all the way to the right,
the squelch may be closed. Adjust the squelch level in this
case.
●
The volume of the beep sound, sidetone and
announcement cannot be adjusted using the [AF]
control.
Adjusting RF Gain
Below are the steps to adjust the gain of the RF amplifier. Under
normal circumstances, turn the [RF] control all the way to the right.

Configuring the screen brightness to “0” and exiting the
menu turns all the lights off. Pressing [MENU] at this time
displays the screen with the dimmest level of brightness.
• Start by checking the peak scale of the S meter, followed by
turning the [RF] control in the anti-clockwise direction
without lowering the peak value of the S meter. Doing so
attenuates signals weaker than this level and eases
reception from the desired station.
• Depending on the type of antenna, gain level and band
condition, better effect may sometimes be achieved by
turning the [RF] control slightly to the left rather than all the
way to the right.
●
In the FM mode, turning the [RF] control does not change
the gain level. Under normal circumstances, turn the
[RF] control all the way to the right.
Adjusting the Squelch Level
Below are steps to adjust the threshold level for squelch, a function
for eliminating noise that is heard when receiving a frequency with
no signal.
Turn the [SQL] control.
Configure the squelch level to the position where noise
disappears. When squelch opens upon receiving a signal, the
[BUSY/TX] LED lights up in green.
●
●
The position of the [SQL] control at which noise
disappears varies according to the strength of the noise
and surrounding conditions such as temperature.
The position of the control knob at which noise
disappears also varies depending on whether this
transceiver is in the FM mode or in other modes.
Selecting VFO A/ B
This transceiver is equipped with two VFOs, A and B. The two
VFOs operate independently of each other, and thus can be
configured to different frequencies and modes. Additionally, one
VFO can be configured to the TX frequency and the other to the
RX frequency.
Press [A/B].
Pressing [A/B] each time switches between “VFO A” and “VFO
B”. The currently selected VFO is indicated as <<
>> or
<<
>>.
• Pressing and holding down [A/B] configures both “VFO A”
and “VFO B” to the same frequency and mode.

Selecting an Operating Band
Below are steps to select the frequency bandwidth to use. A
different frequency bandwidth can be selected for VFO A and VFO
B. By using the numeric keypad or [GENE] key, it is possible to call
up an amateur frequency between 1.8 MHz and 50/70 (E type) MHz
or a general band frequency at one touch.
• This transceiver comes with a band memory feature that is able
to store up to 5 pairs of frequencies and modes (3 pairs in the
default setting) that were used most recently for each band.
Press [1 (1.8)] to [0 (50)] or [GENE].
• Pressing one of the above keys saves the current VFO
frequency and mode and calls up the next memory band at
the same time. Pressing the key each time switches to the
next band memory in sequence from band memory 1 to band
memory 5.

In other words, the communication status of the DX station in
the presence of interfering signals are taken into consideration
and transmission is carried out using the TF-SET function at the
instant when the DX station is in the receiving state and there is
no transmission from other stations. Putting this function to
good use enables communication with a larger number of DX
stations.

AGC (Automatic Gain Control) is a function for controlling the IF
gain automatically so as to minimize fluctuations in the strength of
the signal that is being received.
• The AGC time constant is configured to FAST, MID or SLOW
according to the receiving status and operation mode (other
than FM mode).
• The digital AGC circuit of this transceiver divides the time
constant into 20 levels from SLOW to FAST, with “1” being the
fastest and “20” the slowest.
• Generally, the time constant is configured to a fast time constant
in the CW and FSK modes where fluctuations in the signal
strength are well defined, and a slow time constant is used in
the SSB and AM modes where changes are gradual.
• However, a fast time constant is also useful in the SSB and AM
modes to perform tuning quickly or when receiving weak
signals.
• AGC can also be turned off.
• A different default time constant for AGC is configured for each
mode as shown below.

Adjusting the Sidetone and Pitch Frequency
• During key-down in the CW mode, a tone can be heard from the
speaker of this transceiver. This tone is known as a sidetone.
When this tone is heard, it means it is possible to monitor the
Morse code transmitted by one’s own station.
• In the CW mode for direct keying of the carrier, a BFO (beat
frequency oscillator) is needed to convert the carrier wave into
audible sound. The difference in frequency between the BFO
and carrier wave can be heard in the form of a beat. This
difference in frequency is called RX pitch.
• Both the sidetone and the RX pitch have the same frequency.
Turn the [MIC/PITCH] control.
Configure to a sidetone frequency that can be heard most
clearly. Turning the [MIC/PITCH] control to the right increases
the frequency, while turning the control to the left decreases it.

the point where the output waveform reaches the highest peak.
Configure in Menu [5-15] “CW Rise Time”
Setting
Value
1/ 2/ 4/ 6 (default) [ms]

●
●
Using auto zero-in (CW auto tune) allows tuning up to
±50 Hz from the RX frequency of the target station.
Auto zero-in (CW auto tune) may not be successful when
the keying speed at the receiving station is slow, when
there is interference or when the signals are weak.
When RIT is ON, auto zero-in (CW auto tune) functions
with respect to the frequency shifted using RIT.
The operable range of auto zero-in (CW auto tune) varies
depending on the status of reception. For example, if the
DSP filter width is 500 Hz, auto zero-in (CW auto tune)
will function with respect to RX signals within an
approximate RX pitch frequency range of ±300 Hz.
CW BFO Sideband
This is a function for switching CW (USB) and CW-R (LSB) with
CW (LSB) and CW-R (USB).
Example: Set the CW carrier point to LSB so that the CW RX tone
rises at the same time when the frequency is raised.

CW Automatic Transmission from SSB Mode
When the menu below is configured to ON and paddle or key-down
of the electronic keyer is performed during operation in the SSB
mode, the SSB mode switches automatically to the CW mode and
transmission is enabled in the CW mode. The mode switches
automatically from USB to CW or LSB to CW-R.
• Upon shifting from the SSB mode to the CW mode, carrier
frequency offset will function even when “Carrier Frequency
Offset (SSB Mode to CW Mode)” is set to OFF. For this reason,
to call a station that transmitted a CW after the CW is received
during operation in the SSB mode, this can be done easily using
the paddle or electronic keyer operation.

• Characters/character strings that are received or transmitted
are displayed in the “TX/RX details display area”.
• Eight code abbreviations are supported, namely BT, AR, AS,
HH, SK, KN, BK and SN.
• The code abbreviations are displayed in the “TX/RX details
display area” in the same way as normal character strings. For
example, when “AR” (code with no space between “A” and “R”)
is received, “AR” is displayed.
• The code abbreviations “KN”, “BT” and “AR” have the same
Morse code as the symbols “(”, “=” and “+” respectively. When
these Morse codes are received, they will be displayed as the
code abbreviations received. (Symbols are not displayed.)
• The “*” symbol has the same Morse code as the alphabet “X”.
When this Morse code is received, it will be displayed as the
alphabet “X” received.
• The codes might not be decoded correctly depending on the
signal quality.
• If the keying speed of the target signal changes halfway, the
characters immediately before or after the change cannot be
decoded correctly.

Settings Related to RTTY Encode/Decode
Enabling Decode UOS (Unshift on Space)
If a space character is included in the RTTY signal that is received,
the character following the space can be forcibly interpreted as a
character code (alphabet).
In RTTY, garbled characters may appear due to the signal strength
or noise. To avoid this from happening as much as possible, the
character after a space character is interpreted as a more
frequently used character code (alphabet).
Configure in Menu [2-01] “RX UOS”
Setting
Value
Off/ On (default)
On: Encodes space characters.
Off: Does not encode space characters.
• To receive a numeric value or symbol that immediately
follows a space character, turn off the UOS function.
Newline Code Setting
This is used for sending out a numeric value or symbol that
immediately follows a space during transmission in the RTTY
(FSK) mode. Enabling this function allows the receiving station to
recognize the code that comes after a space as a numeric value
or symbol, thus reducing the occurrence of garbled characters.
Configure in Menu [2-04] “TX UOS”
Setting
Value
Off/ On (default)
On: Uses encode UOS.
Off: Does not use encode UOS.
Sending a Newline Code at the Start or End of a
Transmission
A newline code (CR+LF) can be sent out when RTTY encode/
decode starts or ends. A line break is inserted before and after the
RTTY message on the decode screen of the receiving station,
which makes it easier to identify the transmitted RTTY message.
Configure in Menu [2-05] “Automatic Newline Insertion”
Setting
Value
Off/ On (default)
On: Sends out a newline code.
Off: Does not send out a newline code.
RTTY Parameters
Configuring the Mark Frequency
Configure the frequency of the mark signal that is used for

level from the external device, followed by adjusting the
ALC meter until it starts to deflect.
Displaying the PSK Communication Screen
Operating RTTY Using an External Device
To operate in the RTTY mode using an external device instead of
the built-in encoder and decoder functions of this transceiver by
configuring this transceiver to the RTTY (FSK) mode, make use of
the ACC 2 connector. Connect the keying output line of the
external device to pin 2 (RTTY) of the ACC 2 connector and the
demodulation input line of the external device to pin 3 (ANO) of the
ACC 2 connector. Also, connect the TX control (PTT) line to pin
13 (SS) of the ACC 2 connector.
• For RTTY transmission using PKS/SS signals of the ACC 2
connector, encoding is performed using the RTK signals input
to the ACC 2 connector. However, if the built-in encoder is
activated during transmission via the PKS/SS signals, encoding
will be performed using the built-in encoder and the RTK signals
from the ACC 2 connector will be ignored. (Transmission of the
built-in message memory is also possible during RTTY
operation using an external device.)
See below for examples of the connection setup (1-4).

CTCSS Frequency Scan
CTCSS Operation
CTCSS is the abbreviation for Continuous Tone Coded Squelch
System. It is used to add a CTCSS tone frequency that is
determined in advance with the target station to the audio signal
to be transmitted. When the CTCSS tone frequency contained in
the RX signal received from the target station coincides with the
CTCSS tone frequency of one’s own station, the squelch opens
and the RX audio can be heard.
• A different value can be selected for CTCSS tone frequency and
tone frequency, but CTCSS and tone cannot be used
concurrently.
• CTCSS tone frequency: Squelch opens upon receiving a
CTCSS tone for which the FM wave is superimposed with the
same CTCSS tone frequency as that configured on this
transceiver.
• During CTCSS frequency scan, it is possible to detect the
CTCSS tone frequency that is contained in the RX signal.
• When a signal is received while CTCSS tone frequency scan is
in progress, the RX audio can be heard even when the CTCSS
tone frequency does not coincide with that configured on this
transceiver.

The attenuator is a function for attenuating the RX signals. If there
is interference due to strong signals near the target signal, turning
on the attenuator helps to reduce interference caused by nearby
frequencies.
It is also effective in situations where the RX audio is distorted
when the RX signal is too strong. This transceiver comes with three
different types of attenuators.
The following information is displayed on the filter scope screen.
• Selected RX filter (A, B or C)
• Image of the IF filter passband characteristics
• Demodulated audio signal
• Parameters including the IF filter passband width
• Pitch frequency in the CW mode
• Notch point of the notch filter
• Passband width of the roofing filter

such as when there is input of a large signal.
Sideband on the positive side with respect to the carrier
wave is drawn on the audio scope. In principle, sideband
also exists on the negative side of the carrier wave in the
AM mode. As such, changing the notch point may cause
it to shift to the sideband on the negative side. When a
notch filter is used concurrently, the marker of the notch
point may shift to the sideband on the negative side. In
this case, the marker is displayed in the folded state.
When the marker is in the folded state, it is displayed in
a color that is different from the usual color.

When configured to “Auto”, a roofing filter with a
bandwidth wider than the passband width of the DSP
filter is selected using high cut/low cut or Width/Shift.
When “Auto” is configured in the AM mode, a 6 kHz
roofing filter is automatically selected if the high cutoff
frequency is 3 kHz or lower, and a 15 kHz roofing filter is
selected if the high cutoff frequency is higher than 3 kHz.
When the RX Filter screen is displayed, turning the [HI/
SHIFT] or [LO/WIDTH] control changes the value of the
cutoff frequency (low and high). The cutoff frequency
value (low and high) is displayed on the RX Filter screen.
In the FM mode, the option is fixed at 15 kHz and cannot
be changed.
When the low cutoff frequency is increased until it
reaches the high cutoff frequency, the high cutoff
frequency will also change at the same time while
keeping the passband width at 0 Hz.
When the high cutoff frequency is decreased until it
reaches the low cutoff frequency, the low cutoff
frequency will also change at the same time while
keeping the passband width at 0 Hz.

frequency of 2125 Hz) as well as the low tone (mark frequency of
1275 Hz).
1 Select FSK mode.
2 Press F [APF].
Noise Blanker
The noise blanker is used to reduce pulse noise. This transceiver
is equipped with two types of noise blankers: NB 1 that employs
analog signal processing and NB2 that performs DSP (digital
signal processing) at the IF level. Furthermore, two types of NB2
with different operating principles are available for selection. NB1
and NB2 can be selected for use according to the noise conditions.
They can also be employed at the same time.

NB2
NB2 is a function for blanking pulse noise with a long pulse width
which cannot be blanked by NB1. NB2 is further divided into Type
A and Type B, which can be employed according to the
circumstances. NB2 can also be used together with NB1.

Type A
●
●
As pulse noise remains after blanking when “Type A” is
used, pulse noise might be audible when the target
signal is strong or when there is strong interference
within the passband. Even in such a situation, it has the
effect of bringing up the target signal when AGC gain is
low due to pulse noise.
“Type A” is most effective in cases where weak target
signals are buried in strong pulse noise.
Type B
Pulse Noise
Target Signal
As with NB1, Type B blanks the pulse noise
together with target signal. The pulse
sensitivity level (Level), blanking duration
(Width) and attenuation level (Depth) can
be adjusted.

Noise Reduction
This transceiver comes with two types of noise reduction functions
NR1 and NR2 which are effective for reducing continuous noise.
When NR1 is used, the optimal method is activated according to
the mode in use.
NR1 and NR2 cannot be turned on at the same time.
Configuring the NR1 Effect Level
1 Press [NR] to select Noise Reduction 1.
2 Press and hold [NR] to display the Noise Reduction
1 effect level configuration screen.
Noise Reduction 1 (NR1)
• In the SSB, FM and AM modes, noise reduction uses a
spectrum subtraction system that places focus on the clarity.
• In the CW, FSK and PSK modes, noise reduction employs an
LMS filter system that emphasizes the periodic signal.
• The noise reduction effect for NR1 can be adjusted.
Noise Reduction 2 (NR2)
• NR2 employs an SPAC system for all modes which extracts the
periodic signal. This system detects periodic signals that are
contained in the RX signals, connects the detected periodic
signals and plays them as part of the RX audio. For this reason,
this method is effective for signals with a single frequency such
as CW signals.
• NR2 allows configuration to the optimal RX conditions by
varying the autocorrelation time for periodic signal detection.
• NR2 is most effective in the CW mode. (Use of NR1 is
recommended for modes other than CW.)
●
●
●
Beat signals are also suppressed when NR1 is used in
the SSB, FM and AM modes as it suppresses stationary
signals. This is a theoretical behavior and not a
malfunction.
When NR2 is set to ON in the SSB mode, the signal
clarity may deteriorate, or pulse noise or distortion may
occur. This is a theoretical behavior and not a
malfunction.
NR2 cannot be used in the FM mode.
3 Press F4 [–]/ F5 [+] or turn the [MULTI/CH] control
to change the level of effect.
Setting
Value
1 to 5 (default) to 10 (1 step)
• For NR1, configuring to a larger value reduces the noise
further. However, as the impact on the RX audio also gets
stronger if the effect level is excessively high, adjust it to an
appropriate level.
Configuring the NR2 Correlation Time
1 Press [NR] to select Noise Reduction 2.
2 Press and hold [NR] to display the NR2 Time
Constant configuration screen.
3 Press F4 [–]/ F5 [+] or turn the [MULTI/CH] control
to change the correlation time.
Setting
Value
2 to 20 (default) [ms] (2-step)
• As the optimal correlation time varies with the RX signal and
noise type when NR2 is used, configure the correlation time
while receiving the signals.
●
NR2 adjusts the correlation time for periodic signal
extraction. It is different from NR1, which adjusts the
effect level.

6 REJECTING INTERFERENCE
Beat Canceler
Beat canceler is capable of suppressing multiple periodic
interfering signals (beats) within the RX bandwidth through digital
processing at the AF level.
This function can be used in the SSB, AM and FM modes.
Turning ON/OFF Beat Canceler
Press [BC].
Pressing [BC] each time switches the beat canceler mode in
the following sequence: “Beat Canceler 1” → “Beat Canceler 2”
→ “OFF”.
• When beat canceler 1 or beat canceler 2 is ON, << BC 1 >>
or << BC 2 >> is displayed on the screen.
• Beat canceler 1 suppresses weak beats and continuous
beats. Beat canceler 2 suppresses intermittent beats such
as CW signals.
●
Although the beat canceler suppresses the overall
auditory beat, the gain of the target signal cannot be
recovered using the AGC function. Thus, if the beat
signal is larger than the target signal, using a notch filter
activates the AGC function to enhance the clarity of the
target signal.
DSP Monitor
DSP monitor is a function for temporarily expanding the passband
width of the IF filter and AF filter via DSP in order to monitor the
signal condition of nearby frequencies such as when receiving a
specific frequency using a filter with a narrow passband width
during contesting.
Assigning DSP Monitor to PF Key
Register “DSP MONITOR” in Menu [0-15] “PF A: Key
Assignment” to Menu [0-31] “Microphone UP: Key
Assignment”
Expanding the Passband Width Using DSP Monitor
Press and hold down the PF key that is assigned
with the DSP monitor function.
The passband width of the filter is expanded while the key is
held down.

During DSP monitoring, the audio peak filter is forcibly
turned OFF.
