Make sure that all antenna, power, and microphone connections are correct. Using the normal reception procedure, select a clear frequency free of other stations or select the frequency of a station to communicate with. The red TX LED will be lit. NOTE: Speaking too loud or too close to the microphone may increase distortion. REFERENCE: Adjusting the microphone gain, page 85. 6. Release the [PTT] key to stop transmitting and return to receive. Transmitting in the CW mode Keying will automatically start transmit. 1. 4. Make sure that all antenna, power, and microphone connections are correct. Set the desired BREAK-IN mode (see page 79). NOTE: The default setting is the AUTO BREAK-IN mode, meaning the delay time for the SEMI BREAK-IN mode will be set automatically according to transmitting CW speed. 5. Transmission will stop automatically. 33 Chapter 2 Communications Selecting output power level To select the output power, press [FUNC] key and then press [0] key while "FUNC" icon is on the display. The "S-LOW" icon stands for SUPPER LOW power setting, "LOW" for LOW power. The output power level cannot be changed during transmission. Hi LOW S-LOW SSB, CW, FM AM Hi LOW S-LOW Hi LOW S-LOW 100 W 10 W 1W 40 W 4W 0. 4 W NOTE: The fan starts to run at 60 °C (140°F/inside temperature), and reduces the power by about 50% at 80 °C (176°F). It stops or resumes high power when the inside temperature is cooled down. Speech compressor: increases talk power to enable clear and powerful transmission. See the Set mode Menu 19 (P. 81) for more details. · TXIT (Transmit Incremental Tuning) function (See page 65) * Press the [RIT] key repeatedly until the "TXIT" icon appears. Then rotate the RIT control knob to change the transmit frequency within a range ± 1. 2 kHz. * When the "TXIT/RIT" icon appears, it means that you can fine-adjust both transmit and receive frequencies. · OFF BAND display: Stop transmission when you attempt to transmit outside of the amateur radio band. The LCD will display the following: 34 Chapter 2 Communications 2. 3 SSB Operation Introduction The SSB (Single Side Band) mode is most frequently used for voice communication in HF bands. Procedure NOTE: Make sure that all antenna, power, and microphone connections are correct. 1. There are two types of SSB mode: USB (Upper-Side-Band) and LSB (Lower-SideBand). The LSB or USB mode will be automatically selected according to the selected band. NOTE: · If the Automatic USB/LSB Selection function is set to off, the last-used SSB mode is recalled. · The transceiver's squelch circuit interacts with the S meter. Therefore, if the AGC-F mode is selected in the SSB mode, squelch may be muted and unmuted according to the signal strength. To prevent this, it is recommended to select the AGC-S mode rather than the AGC-F mode. 4. Tune in a station to communicate with. · Fine-tune to a frequency at which the signal from the station is clearly heard. NOTE: · Be sure to set the RIT knob back to the original position before contact is made. Otherwise, your frequency will shift off the other station's frequency. · Check to see the frequency is not used by other stations before transmitting. 35 Chapter 2 Communications 5. Press and hold the [PTT] key and speak into the microphone. [. . . ] * Never use unauthorized contact-cleaners, oil, spray-blower and other materials may be used to clean home appliances.
