扫描Scans
本章介绍 IC-7300 的扫描功能：扫描类型总览（Programmed scan、Memory scan、Select Memory scan、∂F scan），Scan Set 模式中的扫描速度与扫描恢复设置，静噪状态对扫描行为的影响，各类扫描的操作步骤，选择存储通道的设置与取消，以及在 FM 模式下识别中继所需亚音的 Tone scan 操作。
This chapter describes the IC-7300's scan functions: an overview of the scan types (Programmed scan, Memory scan, Select Memory scan and ∂F scan), the Scan speed and Scan Resume settings in the Scan Set mode, how the squelch status affects scanning, the operating procedures for each scan type, setting and canceling Select Memory channels, and the Tone scan operation that identifies the tone frequency needed to access a repeater in the FM mode.
10-2扫描类型Scan types
IC-7300 具有以下几种扫描类型，如下表所列。
The IC-7300 has several scan types as listed below.
| 扫描类型Scan type | 操作Operation |
|---|---|
| Programmed scan (p. 10-3) | 在 2 个扫描边缘频率（扫描边缘存储通道 P1 和 P2）之间反复扫描。扫描从较低的边缘频率开始。Repeatedly scans between 2 Scan Edge frequencies (Scan Edge memory channels P1 and P2). The scan starts from the lower edge frequency. |
| Memory scan (p. 10-4) | 反复扫描所有已存入内容的存储通道。Repeatedly scans all entered Memory channels. |
| Select Memory scan (p. 10-4) | 反复扫描 3 个选择存储通道中的全部或其中一个。Repeatedly scans all or one of 3 select Memory channels. |
| ∂F scan (p. 10-6) | 在 ∂F span 区域内反复扫描。扫描从中心频率开始。Repeatedly scans within the ∂F span area. The scan starts from the center frequency. |

准备Preparation
静噪状态Squelch status
扫描功能与静噪状态联动。请务必根据您的操作环境调整静噪电平。
Scans work with the squelch status. Be sure to adjust the squelch level according to your operating conditions.
提示 NOTENOTE
当 AF/RF/SQL 旋钮仅作为射频增益控制工作时，无法调整静噪电平。
When AF RF/SQL operates as only an RF gain control, you cannot adjust the squelch level.
提示 NOTENOTE
通常，将 AF/RF/SQL 旋钮调到噪声消失、且 TX/RX 指示灯熄灭的位置。
Normally, set AF RF/SQL to the point where noise disappears, and the TX/RX indicator goes off.
扫描在静噪打开的状态下开始时：
When the scan starts with the squelch open:
• 对于编程扫描：当调谐步进为 1 kHz 或以下时，扫描将持续进行，直到手动停止——即使检测到信号也不会暂停*。
• For a Programmed scan: When the tuning step is 1 kHz or less, the scan continues until it is manually stopped — it does not pause* even if signals are detected.
*当静噪关闭后又打开时，扫描暂停。Scan Resume 功能为 ON 时，扫描暂停 10 秒后恢复；该功能为 OFF 时，扫描取消。
*The scan pauses when the squelch is closed and then opened. The scan resumes after 10 seconds has passed when the Scan Resume function is ON. It is cancelled when the function is OFF.
当调谐步进为 5 kHz 或以上时，Scan Resume 功能为 ON 时扫描在每个步进点暂停；该功能为 OFF 时扫描不暂停。
When the tuning step is 5 kHz or more, the scan pauses on each step when the Scan Resume function is ON. It does not pause when the function is OFF.
• 对于存储扫描：Scan Resume 功能为 ON 时扫描在每个通道暂停；该功能为 OFF 时扫描不暂停。
• For a memory scan: The scan pauses on each channel when the Scan Resume function is ON. The scan does not pause when the function is OFF.
扫描在静噪关闭的状态下开始时：检测到信号时扫描停止。
When the scan starts with the squelch closed: The scan stops when a signal is detected.
• Scan Resume 功能为 ON 时，检测到信号后扫描暂停 10 秒，然后在信号消失 2 秒后恢复扫描。
• When the Scan Resume function is ON, the scan pauses for 10 seconds after detecting a signal, then resumes 2 seconds after the signal disappears.
火腿经验 HAM TIPHAM TIP
RF/SQL 是复合旋钮：内环为 AF 音量，外环为 RF 增益/静噪（RF/SQL）；外环以 12 点位置为界——逆时针一侧调射频增益（RF GAIN），顺时针一侧调静噪门限（SQL）。新手常把「没声音」当成故障——先确认外环 RF GAIN 是否被关小、或内环音量是否太小。本章要求按操作环境调整静噪电平；如果发现静噪调不了，先确认电台是否处于 RF/SQL 仅作射频增益工作的状态（见上文说明）。
The RF/SQL control is a dual-concentric knob: the inner ring is AF volume and the outer ring is RF gain/squelch (RF/SQL). The outer ring splits at the 12 o'clock position — counterclockwise adjusts RF GAIN, clockwise adjusts the squelch threshold. Beginners often mistake "no audio" for a fault — first check whether the outer ring's RF GAIN has been turned down, or the inner volume is too low. This chapter tells you to set the squelch for your operating conditions; if you cannot adjust the squelch at all, check whether the rig is in a state where RF/SQL works only as an RF gain control (see the note above).
10-3编程扫描与细编程扫描（VFO 模式）Programmed scan and Fine Programmed scan (VFO mode)
在两个扫描边缘频率之间反复扫描。边缘频率默认预设在 P1 和 P2 中：P1 为 0.500000 MHz，P2 为 29.999999 MHz。扫描从一个扫描边缘频率（P1 或 P2）扫到另一个（P2 或 P1），然后跳回（Jump）起点，如此反复。
Repeatedly scans between two Scan Edge frequencies. The edge frequencies are preset in P1 and P2 as the default. P1: 0.500000 MHz P2: 29.999999 MHz. The scan sweeps from one Scan edge (P1 or P2) to the other (P2 or P1), and then jumps back to the start.
提示 NOTENOTE
要更改 P1 和 P2 扫描边缘存储通道，详见「Entering memory channel contents」（见 9-3 节）。
To change the P1 and P2 Scan Edge Memory channels, see "Entering memory channel contents" (p. 9-3) for details.
提示 NOTENOTE
如果在 P1 和 P2 中输入相同的频率，编程扫描不会启动。
If the same frequencies are entered into P1 and P2, the Programmed scan does not start.
提示 NOTENOTE
在细编程扫描中，静噪打开时扫描速度降低，但收发信机继续扫描。静噪打开时，扫描调谐步进变为 10 Hz。
In the Fine Programmed scan, the scan speed decreases when the squelch opens, but the transceiver keeps scanning. The scan tuning step changes to 10 Hz when the squelch opens.

火腿经验 HAM TIPHAM TIP
玩 FM 中继先用 Tone Scan 找亚音：收到中继后启动 Tone Scan，电台会自动识别 88.5 Hz 等亚音频率并写入 TSQL，省去逐个试听的麻烦。
For FM repeater work, run Tone Scan first to find the tone: after you receive the repeater, start Tone Scan and the rig automatically identifies the tone frequency (e.g., 88.5 Hz) and writes it into TSQL, saving you the trouble of trying each tone by ear.
