准备 Preparation
静噪状态Squelch status
Scans work with the squelch status. Be sure to adjust the 扫描功能与静噪状态联动。请务必根据您的操作环境调整 squelch level according to your operating conditions. 静噪电平。
提示 NOTE NOTE 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 NOTE NOTE 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.
When the scan starts with the squelch open: 扫描在静噪打开的状态下开始时：
• For a Programmed scan: When the tuning step is 1 kHz or • 对于编程扫描：当调谐步进为 1 kHz 或以下时，扫描将 less, the scan continues until it is manually stopped — it 持续进行，直到手动停止——即使检测到信号也不会暂停 does not pause* even if signals are detected. *。
*The scan pauses when the squelch is closed and then *当静噪关闭后又打开时，扫描暂停。Scan Resume 功能 opened. The scan resumes after 10 seconds has passed 为 ON 时，扫描暂停 10 秒后恢复；该功能为 OFF 时，扫 when the Scan Resume function is ON. It is cancelled when 描取消。 the function is OFF.
When the tuning step is 5 kHz or more, the scan pauses on 当调谐步进为 5 kHz 或以上时，Scan Resume 功能为 each step when the Scan Resume function is ON. It does ON 时扫描在每个步进点暂停；该功能为 OFF 时扫描不暂 not pause when the function is OFF. 停。

火腿经验 HAM TIP HAM 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 Programmed scan and Fine Programmed scan (VFO mode) · 编程扫描与细编程扫描（VFO 模式）
Repeatedly scans between two Scan Edge frequencies. The 在两个扫描边缘频率之间反复扫描。边缘频率默认预设在 edge frequencies are preset in P1 and P2 as the default. P1: P1 和 P2 中：P1 为 0.500000 MHz，P2 为 29.999999 0.500000 MHz P2: 29.999999 MHz. The scan sweeps from MHz。扫描从一个扫描边缘频率（P1 或 P2）扫到另一个 one Scan edge (P1 or P2) to the other (P2 or P1), and then （P2 或 P1），然后跳回（Jump）起点，如此反复。 jumps back to the start.
提示 NOTE NOTE 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 NOTE NOTE 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 NOTE NOTE 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.
