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-9100'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. SCP Sweep icon Band scope display Frequency display mark Sweep step display STEP 0.5k INDICATOR DESCRIPTION Sweep icon Band scope display Frequency display mark Sweep step display 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, with each vertical dot in the band scope indicator equal to one segment of the S-meter. 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, hold down [F-3] 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 approximately 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. q Rotate [MAIN DIAL] to select a frequency. w P ush [MENU] to display the "M1" screen (Menu 1), then push [SCP](F-5) to display the "SCP" screen (Band Scope). • Automatically starts sweeping with the previously se- lected sweeping step. • During a sweep, received signals cannot be heard. e P ush [F-5] one or more times to select the desired sweep step. • 0.5, 1, 2, 5, 10, 20 and 25 kHz are selectable. r P ush [F-1] to start sweeping, then automatically stop after sweeping. • Hold down [F-1] for 1 second to start continuous sweep- ing. In this case, push [F-1] again to stop the sweeping. • During a sweep, " " is displayed and received signals cannot be heard. • If there is a lot of signal noise, turn OFF the Preamplifier to reduce the signal input level, and turn ON the Attenuator to improve the readability of the band scope. t R otate [MAIN DIAL] to find a signal that you wish to communicate with. If you find the signal, communicate in the normal way. • If you want to return to the frequency you were using before rotating [MAIN DIAL], hold down [F-3] for 1 second. • If the selected frequency is set outside of the sweeped range, " " or " " blinks. y If you want to update the band conditions while receiving, repeat steps e and r.
