🔍 Key Concepts

• AF (audio frequency) amplifier vs. RF (radio frequency) stages and which one actually drives the speaker • What happens when the PTT (Push-To-Talk) is stuck or accidentally keyed on a VHF set • The role of squelch control and at which part of the receiver chain it has an effect

💭 Think About

• Think about which stage of the radio is responsible for turning the received signal into sound at the speaker — if that stage fails, what symptoms would you expect? • If the PTT circuit is activated on a VHF set, what does that do to the receiver function and the audio output path? • Would a failure in RF, local oscillator, or IF stages typically make the squelch control appear ineffective, or would it more directly affect the ability to receive signals at all?

✅ Before You Answer

• Identify which choice mentions a fault in the audio/speaker path or something that would disable receiver audio when transmitting. • Ask yourself: which faults (RF, LO, IF) would mainly affect tuning and reception rather than speaker audio and squelch operation? • Confirm that the option you pick is consistent with no audible output AND squelch control having no effect, not just "weak" or "no signal" reception.

What fault may exist if a VHF radio receiver fails to produce audible output from the speaker and the squelch control has no effect?

The AF amplifier may be defective or the transmitter Push-To-Talk circuit may be activated .

A component in the RF amplifier stage has failed or the signal from a preceding stage is grounded.

The Local Oscillator stage is no longer supplying a signal to the mixer stage at the correct frequency.

The mixer stage is no longer producing an output signal on the correct Intermediate Frequency (IF).
