Offset Frequency - Icom IC-820H Instruction Manual

@ Offset frequency
Frequencies can be independently set for each
band. Set the desired offset frequency as follows:
Appears when 1 kHz or 1 MHz tuning step is selected.
The display shows a
0.6 (600 kHz) offset
frequency.
() Select the desired band as the main band with
the [M/S] switch.
mi Tone scan
By monitoring a signal that is being transmitted on a
repeater input frequency, you can determine the
tone frequency necessary to open a repeater. The
tone scan can be used in the main band only and an
optional UT-50 is required.
@ Select FM mode with the [FM/RPT] switch.
(2) Set the desired frequency to be checked for a
tone frequency. (e.g. repeater input frequency)
(3) Activate the tone encoder or tone squelch.
@ Push [FUNC], then [SCAN] to start the tone
scan.
The U.S.A. and Australia versions automatically
activate the repeater settings (DUP + or DUP— and
tone encoder ON/OFF) when the operating fre-
quency falls within the general repeater frequency
range and deactivates them when outside of the
range.
See p. 41 for auto repeater selection.
e Programming a repeater frequency
range
The U.S.A. and Australia versions can have 3 re-
peater output frequency ranges set for each band.
For the U.S.A. version, the general repeater fre-
quency ranges (below) are set by default.
@ Program the desired lower repeater output fre-
quency edge and duplex direction (DUP— or
DUP +) into memory channel 1. (p. 30)
(2) Program the desired higher repeater output fre-
quency edge into memory channel 2.
FM REPEATER USE 7
(2) Push [FUNC] then [TONE*SET] to enter set
mode.
@) Push [TONE] twice to select the offset frequency
setting display.
@ Rotate the tuning dial to select the desired fre-
quency.
- Selectable step increment is the same as the preset
tuning step in FM mode. (p. 21)
- 1 kHz tuning step is selected in SSB/CW mode.
- Use [KHz/MHz] for quick frequency setting.
(©) Push [CHECK] to exit the set mode.
The operating
frequency changes to
the tone frequency.
(©) When the tone frequency is matched, the scan
pauses with a beep and the tone frequency is
programmed into the set mode contents of the
subaudible tone or tone squelch frequency.
- The tone frequency is temporally changed when
scanning on a memory or call channel.
Push [SCAN] to stop the tone scan.
- When the scan resume function is cancelled using
the L-set mode the tone scan is cancelled when the
tone frequency is matched. (p. 41)

(3) Program the other frequency edges into memory
channels 3/4 and 5/6 in a similar manner.
-If you do not require more ranges, be sure that
memory channel 3 and/or 5 are set to simplex.
(4) Program the other band edges referring to D)—@).
(©) Turn power OFF, then turn power ON while
pushing [FM/RPT] and [TONE] to program the
ranges.
After programming, the memory channels can be
changed and the ranges do not change if the
contents are changed.
