SCANS
■ ∂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 Push [VFO/MEMO] once or twice to select the VFO
mode or Memory mode.
w Push [MENU] one or more times to display the "M2"
screen (Menu 2).
e Push [SCAN](F-1) to display the "SCAN" screen.
r Rotate the [RF/SQL] control to set the squelch to
open or closed.
• The scan performance differs, depending on the squelch
setting when the scan was started. See page 76 for de-
tails.
• If the [RF/SQL] control function is set to "AUTO," the
squelch is always open in the SSB, CW and RTTY
modes. (pp. 2, 32, 86)
t Push [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 [DIAL] to
set the center frequency.
• In the memory mode, push [Y] or [Z] to select the de-
sired Memory channel whose frequency will be the cen-
ter frequency.
u Push [∂F](F-2) to start or cancel the ∂F scan.
• "∂F SCAN," the MHz and kHz decimal points blink while
scanning.
• Rotating [DIAL] also cancels the 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 a ∂F scan.
• Follow steps q through u as described above.
w While scanning, push [FIN](F-3) to switch the scan
function between ∂F scan and Fine ∂F scan.
• "F-∂F SCAN" blinks while Fine ∂F scanning.
e Push [∂F](F-2) to cancel the scan.
• Rotating [DIAL] also cancels the scan.
