7 BANDSCOPE SWITCHING THE MARKER OFFSET FREQUENCY (SSB ONLY) The marker display location while the bandscope for SSB mode is displayed can be switched to the carrier point which is the same as the frequency display or to a frequency offset from the carrier point. 1 Select Group No. 8, "Bandscope", from the Menu screen. 2 Access Menu 03, "Marker Offset Frequency (SSB Mode)". 3 Press [SELECT] (F4) to allow editing of the parameter box. SELECTING THE FREQUENCY DISPLAY IN THE GRID (RELATIVE FREQUENCY OR ABSOLUTE FREQUENCY) The Bandscope screen shows the signal strength in the vertical axis and the frequency in the horizontal axis. This allows you to select the desired frequency to appear under the grid. If "Off (Carrier Point)" is selected in Menu 8-03, "Marker Offset Frequency (SSB Mode)", the frequency to be displayed below the bandscope for use in Center mode can be switched to the relative frequency from the scope center, i.e. ±25 kHz, or to the absolute frequency. 1 Select Group No. 8, "Bandscope", from the Menu screen. 2 Access Menu 04, "Frequency Scale (Center Mode)". 3 Press [SELECT] (F4) to allow editing of the parameter box. 4 Press [-] (F4) or [+] (F5) to select "Off (Carrier Point)" or the offset frequency. The default is "500 [Hz]" (near the peak of the frequency spectra for the typical human vocal). While the bandscope and Waterfall are displayed, placing a marker near the frequency having the strongest level can easily zero-in even in SSB mode. The peak of the frequency spectra may vary or may not be distinguished due to the audio quality of the transmitting station. 5 Press [ ] (F1). 6 Press [MENU] to exit. Note: ◆◆If the bandscope is in Center mode, the frequency which is added by the frequency configured in Menu 8-03 to the carrier point frequency will be the center frequency for USB mode, and the frequency which is subtracted by the frequency configured in Menu 8-03 from the carrier point frequency will be the center frequency for LSB mode. The lower limit frequency and upper limit frequency appear following the center frequency. ◆◆If the bandscope is in Fixed mode, the frequency which is added by the frequency configured in Menu 8-03 to the carrier point frequency will be the marker frequency for USB mode, and the frequency which is subtracted by the frequency configured in Menu 8-03 from the carrier point frequency will be the marker frequency for LSB mode. 4 Press [-] (F4) or [+] (F5) to select "Relative Frequency" or "Absolute Frequency" in the parameter box. The default is "Relative Frequency". 5 Press [ ] (F1). 6 Press [MENU] to exit. Note: ◆◆If anything other than "Off (Carrier Point)"is selected in Menu 8-03, the relative frequency display is applied, and the absolute frequency may not be displayed. ◆◆In Fixed mode, the absolute frequency always appears regardless of the configuration in Menu 8-03. 7-4 Index Contents
