BANDSCOPE 7 DISPLAYING THE BANDSCOPE AND ANOTHER SCREEN You can display the bandscope while the RTTY Encode/ Decode or PSK Encode/Decode screen appears, provided that the transceiver is in FSK or PSK mode or the configuration screen is displayed. Press [SCP] to display the Bandscope screen with the scale in the vertical direction compressed to 1/3. The [RF/AF] (F2), [ATT] (F5), or other function keys for the bandscope do not appear along the bottom of the main screen while the bandscope appears coupled with the other screen; hence, you cannot change the configurations for the bandscope. CHANGING THE DISPLAYED FREQUENCY SPAN (CENTER MODE) You can change the displayed frequency span (the width of the lower limit and upper limit frequencies on the Bandscope screen) while the bandscope is displayed in Center mode. 1 Press [SPAN] (F4) to change the frequency display span. • Pressing the key each time switches the frequency span in the following sequence: 5 kHz → 10 kHz → 20 kHz → 30 kHz → 50 kHz → 100 kHz → 200 kHz → 500 kHz. Pressing [SPAN] (F) when the span is 500 kHz switches it back to 5 kHz. • Each long press of [SPAN] (F4) cycles the selection in the reversed sequence. • The selected frequency span appears as "SPAN 50 kHz" on the toolbar of the Bandscope screen. • The default is as follows. SSB/ FM/ AM: 50 kHz CW/ FSK/ PSK: 20 kHz • The span is stored separately for CW/ FSK/ PSK mode and SSB /FM /AM mode. • If [SPAN] (F3) is unavailable in the key guide, press [MORE] (F1). TOGGLING THE CENTER MODE AND FIXED MODE There are two modes available, the Center mode which always places the receive frequency at the center of the bandscope, and the Fixed mode which displays fixed lower and upper frequency limits. Follow the procedure below while the bandscope appears. 1 Press [CRT/FIX] (F3) to change the display. • Each time you press [MODE] (F7), the selection toggles between "CENTER MODE" and "FIXED MODE". • If [CTR/FIX] (F3) is unavailable in the key guide, press [MORE] (F1). Note: ◆◆In Fixed mode, with the observation of the target signal (vertical trace) displayed on the Waterfall, shift the marker position to tune the signal. This enables you to tune more easier than in Center mode. Contents Index 7-3

BANDSCOPE 7
Index
Contents
DISPLAYING THE BANDSCOPE AND ANOTHER
SCREEN
You can display the bandscope while the
RTTY Encode/
Decode
or
PSK Encode/Decode
screen appears,
provided that the transceiver is in FSK or PSK mode or the
configuration screen is displayed.
Press
[SCP]
to display the
Bandscope
screen with
the scale in the vertical direction compressed to 1/3.
The
[RF/AF]
(F2),
[ATT]
(F5), or other function keys
for the bandscope do not appear along the bottom of
the main screen while the bandscope appears coupled
with the other screen; hence, you cannot change the
configurations for the bandscope.
[F1]~[F7]
[SCP]
[MENU]
TOGGLING THE CENTER MODE AND FIXED MODE
There are two modes available, the Center mode which
always places the receive frequency at the center of the
bandscope, and the Fixed mode which displays fixed
lower and upper frequency limits.
Follow the procedure below while the bandscope appears.
1
Press
[CRT/FIX]
(F3) to change the display.
Each time you press
[MODE]
(F7), the selection toggles
between "CENTER MODE" and "FIXED MODE".
If
[CTR/FIX]
(F3) is unavailable in the key guide, press
[MORE]
(F1).
Note:
In Fixed mode, with the observation of the target signal (vertical
trace) displayed on the Waterfall, shift the marker position to tune
the signal. This enables you to tune more easier than in Center
mode.
CHANGING THE DISPLAYED FREQUENCY SPAN
±CENTER MODE²
You can change the displayed frequency span (the width
of the lower limit and upper limit frequencies on the
Bandscope screen) while the bandscope is displayed in
Center mode.
1
Press
[SPAN]
(F4) to change the frequency display
span.
Pressing the key each time switches the frequency span
in the following sequence: 5 kHz → 10 kHz → 20 kHz →
30 kHz → 50 kHz → 100 kHz → 200 kHz → 500 kHz.
Pressing
[SPAN]
(F) when the span is 500 kHz switches it
back to 5 kHz.
Each long press of
[SPAN]
(F4) cycles the selection in the
reversed sequence.
The selected frequency span appears as "SPAN 50 kHz"
on the toolbar of the
Bandscope
screen.
The default is as follows.
SSB/ FM/ AM: 50 kHz
CW/ FSK/ PSK: 20 kHz
The span is stored separately for CW/ FSK/ PSK mode and
SSB /FM /AM mode.
If
[SPAN]
(F3) is unavailable in the key guide, press
[MORE]
(F1).
