PANEL DESCRIPTION
■ Front panel (continued)
!3 COMPRESSION LEVEL CONTROL [COMP]
(p. 67)
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. 87)
➥ 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 amplifies received signals in the front end cir-
cuit to improve the S/N ratio and sensitivity. Select “P. AMP1”
or “P. AMP2” when receiving weak signals.
➥ Selects 6 dB, 12 dB or 18 dB attenuator,
or bypasses them.
✔
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 fields, such as from a broadcast-
ing station, are near your location.
