15 OTHER FUNCTIONS Band Scope function Use the Band Scope function to visually search a specified frequency range around the displayed frequency. You can use this function to search for a signal, and see the relative received signal strength level. On the single band display, you can confirm the signal strengths over time by the waterfall function. On the single band display within 137 ~ 174 MHz and 375 ~ 479 MHz, you can hear the displayed frequency's audio during a sweep. The Band Scope function has 2 sweep types. •• Single Sweep: Searches the specified frequency range only once. The Single Sweep starts from the lower frequency, and the sweep stops after reaching the upper frequency. •• Continuous Sweep: Repeatedly searches the specified frequency range. The transceiver's sweep bandwidth is ± 15* × the tuning step number, centered on the operating frequency. * You can change the displayed steps to ± 20 steps. ([MENU] > SET > Scope > Displayed Steps) During a sweep in the Center mode Center frequency (Example: 146.010 MHz) You can select the Band Scope display mode from three modes, the Center mode, the FIX mode, and the Scroll (FIX) mode. Center mode Displays signals around the operating frequency within the selected span. FIX mode Displays signals within a specified frequency range.
