CW BREAK-IN CHANGING KEYING SPEED

Break-in allows you to transmit CW without manually switching between transmit and receive modes. Two types of Break-ins 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 receive mode.

Full Break-in:

As soon as the key contacts open, the transceiver returns to receive mode.

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. You will obtain the best results by selecting a speed that is close to the speed used by the other station.

1Press [CW/ FSK/ REV] to select CW mode.

•“CW” appears.

2Press [KEY/ DELAY].

•The current keying speed appears. The default is 20 (WPM).

USING SEMI BREAK-IN OR FULL BREAK-IN

1Press [CW/ FSK/ REV] to select CW mode.

•“CW” appears.

2Press [VOX/ LEVEL].

•The VOX LED lights.

3Press [FUNC], [KEY/ DELAY].

•The current setting (Full or delay time) appears. The default is Full Break-in.

4Turn the MULTI/ CH control to select Full Break-in or a delay time for Semi Break-in.

•Delay time ranges from 5 to 100 (50 ms to 1000 ms) in steps of 5.

5Begin sending.

•The transceiver automatically switches to transmit mode.

•When FBK (Full Break-in) is selected: The transceiver immediately switches to receive mode when the key opens.

•When a delay time is selected:

The transceiver switches to receive mode after the delay time that you have selected has passed.

6Press [FUNC], [KEY/ DELAY] again.

Note: Full Break-in cannot be used with the TL-922/922A linear 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. Refer to “Keys for CW (PADDLE and KEY)” {page 3} for details regarding this connection. The built-in keyer supports lambic operation.

3While keying the paddle and listening to the transmit sidetone, turn the MULTI/ CH control to select the appropriate speed.

•The speeds range from 10 (WPM) to 60 (WPM), in steps of 1. The larger the number, the faster the speed.

4Press [KEY/ DELAY] 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. 33 to select AUTO, or 2.5 ~ 4.0 (in steps of 0.1) fix weight ratio. The default is AUTO. When the fix weight ratio is selected, the dot/dash weight ratio is locked regardless of the keying speed.

■Reverse Keying Weight Ratio

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. 34, and select ON. The default is OFF.

Reverse	Keying Speed (WPM)
Keying
	10 ~ 25	26 ~ 45	46 ~ 60
Weight
OFF	1:2.5	1:3.0	1:3.2
ON	1:3.2	1:3.0	1:2.8
