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/SQL——默认以 12 点钟位置为界,逆时针一侧调射频增益(RF GAIN),顺时针一侧调静噪(SQL)。新手常把「没声音」当成故障——先确认射频增益是否被关小,或静噪是否被开得过 大。 The RF/SQL control is a dual-concentric knob: the inner ring is AF (volume) and the outer ring is RF/SQL — by default, the counterclockwise side of the 12 o'clock position adjusts the RF gain, and the clockwise side adjusts the squelch. Beginners often mistake "no audio" for a fault — first check whether the RF gain has been turned down, or the squelch opened too far.
