9 TRANSMIT FUNCTIONS SELECTING THE FREQUENCY CHARACTERISTICS OF THE TX DSP EQUALIZER The transceiver is equipped with six types of frequency characteristics for the TX DSP equalizer. In addition, three types of frequency characteristics are available, each of which can be changed according to your preference. Select a frequency characteristic as follows. 1 Press a mode key to select SSB, AM, FM, SSB-DATA, AM-DATA or FM-DATA mode. 2 Press and hold [TXEQ/SEL] to open the TX Equalizer screen. 10 5 0 -5 -10 -15 -20 -25 -30100 101 102 103 5SBOTNJU

)[ 4 Press [ESC], or press and hold [TXEQ/SEL] to exit. Note: ◆◆The on/off status of the TX DSP equalizer and the characteristics of the equalizer are stored in the SSB, FM, AM, SSB-DATA, FM-DATA and AM-DATA modes. ADJUSTING THE TX DSP EQUALIZER You can adjust the frequency characteristic using the TX DSP equalizer to reach your preferred audio quality. 3 Press [ ] (F2) or [ ] (F3), or rotate the MULTI/CH control to select the desired characteristics of the speech processor. You can select the desired option from the equalizer effects as shown in the table below. Effect Purpose High-pass frequency components are High Boost 1 emphasized. This configuration is effective (High-pass boost 1) for audio that contains low-pass frequency components. High-pass frequency components are High Boost 2 emphasized. This configuration provides (High-pass boost 2) characteristics that halve the low-pass attenuation level of High Boost 1. Formant Pass (Formant pass) This configuration attenuates frequency components outside the audio band, thus providing legible characteristics. Low-pass frequency components are Bass Boost 1 emphasized. This configuration is effective (Low-pass boost 1) for audio that contains high-pass frequency components. Low-pass frequency components are Bass Boost 2 emphasized. This configuration provides (Low-pass boost 2) characteristics that further emphasize the low- passband, compared with Bass Boost 1. The frequency domain ranging from 600 Hz and Conventional above is emphasized by 3 dB. This configuration (Pseudo-analog is suitable for communication characteristics characteristics) that loosely attenuate low-pass frequency components. User 1 (User Configuration 1) User 2 (User Configuration 2) You can save your preferred frequency characteristics as User 1, User 2 and User 3. The default is the flat characteristics. User 3 (User Configuration 3) .PEF
LFZT 1 Select SSB, AM, or FM mode on the transmit mode. 2 Press and hold [TXEQ/SEL] to open the TX Equalizer screen. 3 Press [ ] (F2) or [ ] (F3), or rotate the MULTI/CH control to select the desired characteristics. 9-10 Index Contents
