■ ∂F scan and Fine ∂F scan ∂F (Delta Frequency) scan searches for signals within the specified range with the displayed VFO frequency or Memory channel frequency as the center frequency. The frequency range is specified by the width of the selected span. q P ush [VFO/MEMO] once or twice to select the VFO mode or memory mode. w P ush [MENU] one or more times to display the "M2" screen (Menu 2). e P ush [SCAN](F-1) to display the "SCAN" screen. r Set [RF/SQL] open or closed. • The scan performance differs, depending on the squelch setting when the scan was started. See page 146 for details. • If the [RF/SQL] control function is set to "AUTO," the squelch is always open in the SSB, CW and RTTY modes. (pp. 44, 162) t P ush [SPAN](F-4) one or more times to select the desired ∂F span width. • ±5 kHz, ±10 kHz, ±20 kHz, ±50 kHz, ±100 kHz, ±500 kHz and ±1 MHz are selectable. y Set the center frequency of the ∂F scan. • In the VFO mode, push the keypad or rotate [MAIN DIAL] to set the center frequency. • In the memory mode, rotate [M-CH] to select the desired Memory channel whose frequency will be the center frequency. u Push [∂F](F-2) to start the ∂F scan. • "∂F SCAN," the MHz and kHz decimal points blink while scanning. • If "Up/Down" is selected as the "MAIN DIAL (SCAN)" option in the Scan Set mode, rotating [MAIN DIAL] changes the scanning direction. (p. 147) i W hen the scan detects a signal, the scan stops, pauses or ignores it, depending on the Scan Resume function, VSC function or the squelch status. o Push [∂F](F-2) again to cancel the ∂F scan. D About the Fine ∂F scan When a signal is received during Fine ∂F scan, the scanning tuning step is temporarily set to 10 Hz and the scan speed decreases. q Start ∂F scan. • Follow steps q through u as described above. w W hile scanning, push [FIN](F-3) to switch the scan function between ∂F scan and Fine ∂F scan. e Push [∂F](F-2) to cancel the scan.
