CW BREAK-IN
Break-in allows you to transmit CW without manually
switching between transmit and receive modes. Two
types of Break-in are available, Semi Break-in and Full
Break-in.
Semi Break-in:
When the key contacts open, the transceiver
automatically waits for the passage of the time period
that you have selected. The transceiver then returns to
the receive mode.
Full Break-in:
As soon as the key contacts open, the transceiver
returns to the receive mode.
USING SEMI BREAK-IN OR FULL BREAK-IN
1 Press [CW/FSK] to select CW mode.
• “CW” appears.
2 Press [VOX].
• “VOX” appears.
3 Press [DELAY].
• The current setting (Full or delay time) appears.
The default is Full (“FBk”).
4 Turn the MULTI/CH control to select Full Break-in or
a delay time for Semi Break-in.
•Available delay times are from 5 to 100 (50 ms to
1000 ms) in steps of 5.
5 Begin sending.
• The transceiver automatically switches to the
transmit mode.
• When Full is selected: The transceiver
immediately switches to the receive mode when
the key opens.
• When a delay time is selected: The transceiver
switches to the receive mode after the delay time
that you have selected has passed.
6 Press [DELAY] again.
Note:
Full Break-in cannot be used with the TL-922/922A amplifier.
ELECTRONIC KEYER
This transceiver has a built-in electronic keyer that can
be used by connecting a keyer paddle to the
transceiver’s rear panel. Consult “Keys and Keyboards
for CW Operation” {page 3} for details regarding this
connection. This built-in keyer supports lambic
operation.
CHANGING KEYING SPEED
The keying speed of the electronic keyer is fully
adjustable. Selecting the appropriate speed is
important in order to send error-free CW that other
operators can copy solidly. Selecting a speed that is
beyond your keying ability will only result in mistakes. If
you select a speed that is close to the speed used by
the other station, you will obtain the best results.
1 Press [CW/FSK] to select CW mode.
• “CW” appears.
2 Press [KEY].
• The current keying speed appears. The default
is 20.
3 While keying the paddle and listening to the transmit
sidetone, turn the MULTI/CH control to select the
appropriate speed.
• The selectable range is 0 to 100 in steps of 2.
The larger the number, the faster the speed.
4 Press [KEY] again to complete the setting.
Note:
When using the semi-automatic “Bug” function, the selected
speed applies only to the rate that dots are sent.
AUTO WEIGHTING
The electronic keyer can automatically change the dot/
dash weighting. Weighting is the ratio of dash length to
dot length. The weighting changes with your keying
speed thus making your keying easier for other
operators to copy.
Use Menu No. 26 to switch Auto Weighting ON or OFF.
The default is ON. When Auto Weighting is OFF, the
weighting is locked at 3:1.
■ Reversible Auto Weighting
Auto Weighting increases the weighting as you
increase your keying speed. However, the electronic
keyer also can decrease the weighting as you
increase your keying speed.
To switch this function ON, access Menu No. 27, and
select ON. The default is OFF.
