7 BANDSCOPE COLOR TYPE OF WATERFALL You can switch the range of color change corresponding to the signal strength in the waterfall display. When the signal strength is weakest, blue is displayed for Type 1 and black is displayed for Type 2. (The color change in the order of strong signal strength is from white to red to yellow to green to blue for Type 1 and from white to red to yellow to green to blue to black for Type 2.) 1 Select Group No. 8, "Bandscope", from the Menu screen. 2 Access Menu 35, "Waterfall Color Type". 3 Press [SELECT] (F4) to allow editing of the parameter box. 4 Press [-] (F4) or [+] (F5) to select "Type 1" or "Type 2" in the parameter box. The default is "Type 1". 5 Press [ ] (F1). 6 Press [MENU] to exit. CONFIGURING THE WATERFALL DISPLAY FALL SPEED The fall speed of the waterfall display can be configured. 1 Press [SPEED] (F4) to select the waterfall speed. • Each time you press [SPEED] (F4), the fall speed cycles through "Speed 1" (60 seconds) > "Speed 2" (20 seconds) > "Speed 3" (8 seconds) > "Speed 1". The default is "Speed 3". • If [SPEED] (F4) is unavailable in the key guide, press [MORE] (F1). • Each long press of [SPEED] (F4) cycles the fall speed in the reversed sequence. CHANGING THE DISPLAY OF THE BANDSCOPE (MAIN BAND AND Sub band) The signal to be displayed in the bandscope can be selected from the main band signal or sub band signal. Follow the procedure below while the bandscope appears. 1 Press [M/S] (F2) to toggle the selected band between the main band and the sub band. • Each time you press [M/S] (F2), the selection toggles between [MAIN] and [SUB]. Each time the selection is toggled, the markers for the lower limit frequency displayed on the upper left side of the grid, and the upper limit frequency displayed on the upper right side of the grid will change. • If [M/S] (F2) is unavailable in the key guide, press [MORE] (F1). ADJUSTING THE REFERENCE LEVEL If it is not easy to distinguish the target signal from the noise in the noisy environment or if you observe a weak signal on a quiet band, the reference level for the bandscope can be adjusted to allow you to distinguish the target signal. 1 Press [REF.LEV] (F5) to display the current value of the reference level at the center of the Bandscope screen. 2 Observe the spectra of the bandscope waveform and waterfall on the Bandscope screen, rotate the MULTI/ CH control to adjust the reference level in the range from -20 dB to +10 dB. 3 Press [REF.LEV] (F5) to finish the adjustment for the reference level. Note: ◆◆If the target signal cannot be distinguished due to the excessively large input signal even after the reference level has been adjusted, the attenuation level of the bandscope can be changed. {page 7-9} ◆◆The adjustment value of the reference level is stored for each amateur band. 7-2 Index Contents
