Previous view 5 FUNCTIONS FOR RECEIVE Simple Band Scope The Band Scope function allows you to visually check the location and strength of signals around a specified frequency. The IC-7100's Band Scope function can be used in any operating mode and any frequency band. Blinks when the reference frequency is outside of the sweep range. Sweep step Band scope display Frequency display mark display INDICATOR Sweep icon Band scope display Frequency display mark Sweep step display DESCRIPTION While the band scope is sweeping, "" is displayed; while stopped, "" is displayed. Received audio is not heard from the speaker while the band scope is sweeping. Displays the signal location and strength in relation to the center (displayed) frequency. Signal strength is relative to the S-meter level, S1 to S9+30 dB, with each vertical dot in the band scope indicators 1 to 15 dots. Between +30 dB to +60 dB are also displayed by 15 dots. Signal activity is measured ±30 steps from the center frequency, with each step equal to the selected sweep step. After a sweep, displays the relative position of the reference frequency. When the reference frequency is outside of the sweep range, " " or " " blinks. After changing the frequency, touch [RCL](D) for 1 second to automatically return to the center frequency. Displays the selected sweep step. 0.5, 1, 2, 5, 10, 20 and 25 kHz are selectable. Each dot of the band scope display is equal to the selected sweep step. The band scope measures receive signal location and strength over a specified range on either side of a selected frequency, in either the VFO or memory modes. qqRotate the Dial to select a frequency. wwPush MENU (C) one or more times to select the "M-3" screen (M-3 menu). eeTouch [SCOPE](D) to display the "SCOPE" screen (Band Scope). • Automatically starts sweeping with the previously select- ed sweeping step. • During a sweep, received signals cannot be heard. rrTouch [STEP](D) one or more times to select the desired sweep step. • 0.5, 1, 2, 5, 10, 20 and 25 kHz are selectable. ttTouch [](D) to start sweeping, then automatically stop after sweeping. • Touch [](D) for 1 second to start continuous sweep- ing.

If you find the signal, communicate in the normal way. • If you want to return to the frequency you were using before rotating the Dial, touch [RCL](D) for 1 second. • If the selected frequency is set outside of the sweep range, " " or " " blinks. uuIf you want to update the band conditions while receiving, repeat steps r and t. Touch [SCOPE] Sweep start/stop Sweep icon Sweep step selection NOTE: If you select a large sweep step, a wide frequency range can be displayed on the band scope, but some signals may be skipped and not displayed. 5-14
