CW BREAK-IN Break-in allows you to transmit CW without manually switching between transmission and reception 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 duration of the time period you selected. The transceiver then returns to reception mode. Full Break-in: As soon as the key contacts open, the transceiver returns to reception mode. USING SEMI BREAK-IN OR FULL BREAK-IN 1 Press [CW/FSK (REV)] until you select CW mode. • "CW" appears. 2 Press [VOX (LEV)]. • " " appears. 3 Press and hold [KEY (DELAY)]. • The current setting (FBK or delay time) appears. The default is 50 (500 ms). 4 Turn the MULTI/CH control to select "FBK" (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. 5 Begin sending. • The transceiver automatically switches to transmission mode. • When FBK (Full Break-in) is selected: The transceiver immediately switches to reception mode when the key opens. • When a delay time is selected: The transceiver switches to reception mode after the delay time that you have selected has passed. 6 Press [CLR] to exit. Note: FBK (Full Break-in) cannot be used with the TL-922/ 922A linear amplifier. 7 COMMUNICATING AIDS 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 2} for details regarding this connection. The built-in keyer supports lambic (squeeze) operation. ELECTRONIC KEYER MODE There are 2 modes of operation when using an electronic keyer for lambic keying operation. Mode A completes the current key sequence you are sending when you release the paddles. Mode B sends one more key, opposite the current key you are sending, upon releasing the paddles. 1 Press [MENU], then press [Q-M.IN]/ [Q-MR] or turn the MULTI/CH control to select Menu No. 32. 2 Press [M.IN]/ [SCAN (SG.SEL)] to select "A" or "B" (default). 3 Press [MENU] to exit Menu mode. 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. You will obtain the best results by selecting a speed that is close to the speed used by the other station. 1 Press [CW/FSK (REV)] until you select CW mode. • "CW" appears. 2 Press [KEY (DELAY)]. • The current keying speed appears. The default is 20 (wpm). 3 While keying the paddle and listening to the TX (transmission) sidetone, turn the MULTI/CH control to select the appropriate speed. • The speeds range from 4 to 60 wpm, in steps of 1 wpm. The larger the number, the faster the speed. 4 Press [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. ■ Invalid Break-In Operation You can make break-in operation invalid while performing the keying speed adjustment. To switch this function ON, access Menu No. 43, and select "on" (default is "oFF"). • "VOX" blinks when break-in operation is enabled. 33
