!3
COMPRESSION LEVEL CONTROL [COMP]
(p. 68)
Adjusts the speech compression level in SSB.
!4
SEMI BREAK-IN DELAY CONTROL
[BK-IN DELAY]
Adjusts the transmit-to-receive switching delay time
for CW semi break-in operation.
!5
ELECTRONIC CW KEYER SPEED CONTROL
[KEY SPEED]
(p. 35)
Adjusts the internal electronic CW keyer’s speed.
• 6 wpm (min.) to 60 wpm (max.) can be set.
!6
MULTI-FUNCTION SWITCHES
Push to select the functions indicated in the LCD
display to the right of these switches.
• Functions vary depending on the operating condition.
➥
Selects the antenna connector between
ANT1 and ANT2 when pushed. (p. 88)
➥
Turns the
[RX ANT]
(receive antenna)
ON
and OFF when pushed for 1 sec.
• When the receive antenna is activated, the
antenna which is connected to the
[ANT1]
or
[ANT2]
is used for transmission only.
When a transverter is in use, this
[ANT]
does not function and ‘XVERT’ appears.
➥
Selects RF power
(Po)
, SWR, ALC or
COMP metering during transmit. (p. 31)
➥
Switches the multi-function digital meter
ON and OFF when pushed for 1 sec.
➥
Selects one of 2 receive RF preamps or
bypasses them. (p. 57)
• “P. AMP1” activates 10 dB preamp.
• “P. AMP2” activates 16 dB high-gain preamp.
✔
What is the preamp?
The preamp ampli
fi
es received signals in the front end cir-
cuit to improve the S/N ratio and increase the sensitivity. Se-
lect “P. AMP1” or “P. AMP2” when receiving weak signals.
➥
Selects 6 dB, 12 dB or 18 dB attenuator,
or bypasses them. (p. 57)
✔
What is the attenuator?
The attenuator prevents a desired signal from distorting
when very strong signals are near the desired frequency, or
when very strong electric
fi
elds, such as from a broadcast-
ing station, are near your location.
