The squelch control should be turned counterclockwise until just beyond the point where the what disappears?

• A. SIGNAL
• B. RECEPTION
• C. SOUND
• D. NOISE

Answer: (C)

Squelch is all about what you hear through the speaker. It mutes the audio when there isn’t a meaningful signal so you don’t have to listen to hiss and static. You adjust it to reach the point where the audible sound would disappear if the signal becomes too weak, then back off a touch so a weak transmission still comes through. That boundary—the point at which the audible sound disappears—is why the correct choice is the sound. The other options refer to aspects the squelch doesn’t directly set: the mere presence of a signal, the overall reception, or the noise level itself, rather than what you actually hear through the speaker.
