Which of the following can eliminate distorted voice transmissions?
Adding extra feedline to the antenna to lower SWR
Turning the radio on and off to reset the computer-controlled circuitry
Adding a clip-on ferrite “choke” to the microphone cable to prevent the transmitted signal from feeding back into the transmitter✓الإجابة الصحيحة
Turning the squelch control fully clockwise to prevent the transmitted signal from triggering the squelch circuit
الشرح
Poor transmitted voice quality is often caused by RF from the antenna coupling into the microphone cable and back into the transmitter's audio stages, a form of RF feedback. A clip-on ferrite choke raises the impedance to that common-mode RF current on the cable without affecting the wanted audio; the other choices address unrelated functions.
