What is the speech compressor?
The speech compressor compresses the transmitter
audio input to increase the average audio output level.
Therefore, talk power is increased. This function is effec-
tive for long distance communication or when propaga-
tion conditions are poor.
!9 ELECTRONIC CW KEYER SPEED CONTROL
[KEY SPEED] (p. 35)
Adjusts the internal electronic CW keyer’s speed.
- 7 wpm (min.) to 56 wpm (max.) can be set.
@0 SEMI BREAK-IN DELAY CONTROL
[BK-IN DELAY]
Adjusts the transmit-to-receive switching delay time
for CW semi break-in operation.
@1 MODE SWITCHES
Selects the desired mode. (p. 25)
- Announces the selected mode when an optional UT-102
is installed. (pgs. 59, 61)
•Selects SSB and SSB narrow (USB-N,
LSB-N) mode alternately.
•Toggles USB and LSB mode when pushed
for 2 sec.
•Selects CW and CW narrow (CW-N) mode
alternately.
•Toggles CW and CW-R (CW reverse)
mode when pushed for 2 sec.
•Selects RTTY and RTTY narrow (RTTY-N)
mode alternately.
•Toggles RTTY and RTTY-R (RTTY re-
verse) mode when pushed for 2 sec.
•Selects AM and AM narrow (AM-N) mode
alternately.
•Selects FM and FM narrow (FM-N) mode
alternately.
•Toggles the subaudible tone encoder ON
and OFF in FM mode when pushed for 2
sec. (pgs. 38, 57)
@2 LCD FUNCTION SWITCHES [F-1]–[F-5]
Push to select the function indicated in the LCD dis-
play above these switches.
- Functions vary depending on the operating condition.
@3 SPEECH SWITCH [SPEECH] (pgs. 59, 61)
Announces the selected readout frequency when an
optional UT-102 is installed.
@4 TUNING DIAL (p. 23)
Changes the displayed frequency, selects set mode
items, etc.
@5 MAIN/SUB SWITCH [MAIN/SUB]
Selects the main or sub readout for access.
- The sub readout frequency is displayed in outline and
functions only during split operation or dualwatch.
@6 VFO/MEMORY SWITCH [VFO/MEMO]
•Toggles the selected readout operating mode be-
tween the VFO mode and memory mode when
pushed. (pgs. 22, 41)
•Transfers the memory contents to VFO when
pushed for 2 sec. (p. 44)
@7 MAIN/SUB CHANGE SWITCH [CHANGE]
•Toggles the frequency and selected memory chan-
nel between main and sub readouts when pushed.
- Toggles between transmit frequency and receive fre-
quency when the split frequency function is ON. (p. 31)
•Equalizes the sub readout frequency to the main
readout frequency when pushed for 2 sec.
@8 DUALWATCH SWITCH [DUALWATCH] (p. 30)
•Turns the dualwatch function ON and OFF when
pushed.
•Turns the dualwatch function ON and equalizes the
sub readout frequency to the main readout when
pushed for 2 sec. (Quick dualwatch function)
- The quick dualwatch function can be turned OFF using
set mode. (p. 56)
@9 SPLIT SWITCH [SPLIT] (p. 31)
•Turns the split function ON and OFF when pushed.
•Turns the split function ON, equalizes the sub
readout frequency to the main readout and sets
the sub readout for frequency input when pushed
for 2 sec. in non-FM modes. (Quick split function)
- The offset frequency is shifted from the main readout
frequency in FM mode. (pgs. 38, 57)
•Turns the split function ON and shifts the sub read-
out frequency after inputting an offset (±1 MHz in 1
kHz steps).
