4 BASIC OPERATIONS Transmission Audio Transmission 1 Press and hold the [PTT] key on the microphone or press the [SEND] key. The transmitting status is activated and the [BUSY/TX] LED lights up in red. 2 Speak into the microphone in the normal tone and loudness. 3 Release the [PTT] key on the microphone or press the [SEND] key. Doing so restores the receiving status. CW Transmission Performing the following steps when a key or paddle is connected enables transmission in the CW mode. 1 Press [CW/ CW-R] to select CW mode. 2 Press [VOX] to enable break-in. 3 Operate the keyer or paddle. Adjusting Microphone Gain Microphone gain can be adjusted in the SSB or AM mode as follows while referring to the ALC meter display. 1 Press and hold the [PTT] key on the microphone or press the [SEND] key. • The transmitting status is activated and the [BUSY/TX] LED lights up in red. 2 Speak into the microphone in the normal tone and loudness. 3 Turn the [MIC/PITCH] control to adjust the microphone gain level. Microphone gain is displayed as "MIC:nnn" at the top of the screen. [nnn: 0 to 100] Adjusting TX Output Power Maintain a TX output power level that is as low as possible while ensuring that communication can be carried out smoothly. Doing so reduces the likelihood of interference with other stations. The TX output power level can also be adjusted while transmission is in progress. Turn the [POWER] control to adjust the TX output power. Turning the [POWER] control to the right increases the output level, while turning it to the left reduces the output level. The selectable range varies with the band and mode in use as follows. HF Band 50 MHz Band 70 MHz Band (E type) Other than AM 5 to 100 [W] 5 to 100 [W] 5 to 50 [W] AM 5 to 25 [W] 5 to 25 [W] 5 to 12.5 [W] ● Output is displayed in a step size of 1 W. An output of 12.5 W will be shown as "12 W". Fine Adjustment of TX Output Power It is possible to alter the step size when the [POWER] control is turned. Configure in Menu [6-04] "Transmit Power Step Size" Setting Value 1 [W]/ 5 (default) [W] 1[W]: Adjusts the TX output level in a step size of 1 W. 5[W]: Adjusts the TX output level in a step size of 5 W (e.g., 5, 10, 15...). . When in the SSB mode Turn the [MIC/PITCH] control while speaking into the microphone. The ALC meter fluctuates according to the volume level. Ensure that the maximum level does not exceed the ALC zone during the adjustment. When in the AM mode Turn the [MIC/PITCH] control while speaking into the microphone. Adjust in such a way that the PWR meter fluctuates slightly according to the volume level. 4 Release the [PTT] key on the microphone or press the [SEND] key. Depending on the squelch level setting, the [BUSY/TX] LED may light up in green or go off. ● Speak into the microphone in the normal tone and loudness. Make sure that your mouth is not too close to the microphone and do not speak too loudly. Doing so may increase the extent of distortion, thus causing audibility to deteriorate at the receiving end. ● To use a speech processor, refer to "Speech Processor" (8-4). ● Note that the output level tend to be larger when a microphone with a built-in AF amplifier is used. ● Microphone gain in the FM mode can be configured in Advanced Menu [10] "Microphone Gain (FM Mode)". 4-8
