Operation In Narrow Fm Mode; Operating The Fm Repeater; Configuring The Tone Signal; Selecting A Tone - Kenwood TS-890S Instruction Manual

Operation in Narrow FM Mode

It is possible to switch to a narrow bandwidth during operation in
the FM mode. The occupied bandwidth and maximum modulation
factor are shown in the table below. Selecting FM Narrow
according to the modulation factor of the target station helps to
avoid distortion and deterioration in the clarity of the RX audio.
Mode Occupied Bandwidth
FM (Wide) 16 kHz or lower
FM Narrow 10 kHz or lower
Press and hold [FM/AM].
Pressing and holding [FM/AM] each time switches between
"FM" and "FMN (Narrow)".

Configuring the Tone Signal

Registering the tone settings to a memory channel and
●
calling up the frequency or operation information from
the memory channel eliminates the need to configure the
tone frequency each time. For more details on the
memory channel settings, please refer to

or region this transceiver is being used.

Selecting a Tone

Press F4 [TONE] to select "TONE".
Pressing F4 [TONE] each time toggles the tone signal selection
in the following sequence: "TONE" → "CTCSS (CT)" →
"CROSS" → Blank (deselected).

Tone Frequency Scan

Tone frequency that is contained in signals received in the FM
mode can be searched and displayed with the following steps. This
is useful when there is a need to know the tone frequency of the
repeater station.

• Scanning stops when a tone frequency is detected, and the
frequency is displayed in the "FREQ. [Hz]" field.
• Pressing F7 [SCAN] while tone frequency scan is in
progress stops the scan operation. Pressing F7 [SCAN]
again resume scanning.
• The scan operation stops when the RX signal is interrupted
during tone frequency scan. Scanning resumes when a RX
signal is detected by this transceiver.
