CW BREAK-IN
Break-in is a convenient function in CW mode that places
the transceiver into transmit when the key contacts close
and reverts the transceiver to receive when the key
contacts open. Two break-in modes are available, i.e., full
break-in and semi break-in modes.
[CW/CW-R]
[FBK]
[DELAY]
[VOX/SEL]
FULL BREAK-IN
The transceiver enters the receive mode simultaneously
with the key released. The transceiver enters the receive
mode even during the very short time between a dot and
dash of Morse code. Therefore, for example, you will
know the band condition immediately if there is sudden
interference while transmitting.
1 Press [CW/ CW-R] to select CW mode.
2 Press [FBK] to enable the Full Break-in.
The "FBK" LED lights.
3 Manipulate the electronic keyer or paddle.
The transceiver alternates between transmission and
reception automatically between dots and dashes.
Note:
◆ If you use a linear amplifier in combination with the transceiver, be
sure that the linear amplifier is capable of full break-in. If you do not
know whether the linear amplifier is capable of the function or if the
linear amplifier does not correspond to the function, operate the
transceiver in semi break-in mode.
◆ Full Break-in and Semi Break-in cannot be used at the same time.
SEMI BREAK-IN
The transceiver does not revert to a receive state
immediately after the key is released. Instead, the
transceiver remains in a transmit for a configured delay
time before reverting to the receive state. Semi break-in is
useful to prevent the sound of reception immediately after
the key is released, or to connect a linear amplifier to the
transceiver.
1 Press [CW/ CW-R] to select CW mode.
2 Press [VOX/SEL] to enable the Semi Break-in.
The "VOX" LED lights.
3 Manipulate the electronic keyer or paddle.
The transceiver enters the transmit mode on the first key-
down and doesn’t revert to receive on key-up until the
configured delay time has passed.
4 Rotate the DELAY control to adjust the delay time after
a key-up.
Rotating the DELAY control counterclockwise reduces the
delay time and clockwise increases the delay time.
Note:
◆ Use Semi Break-in if the linear amplifier connected to the
transceiver is not capable of Full Break-in.
