On the PTT switch inside the mic housing, many times you may be able to use contacts ( like if a SPDT - leaf switch ) to reconnect the mic element wires so that the switch is normally closed across the mic wires. If you cannot find any issues with the wiring, your lithium-ion battery may have died. If you just don't have much metal on the vehicle, like with an RV or motorcycle, you may want to go with a no-ground plane (NGP) CB antenna.

On the CB mic - most likely the 4 pins will be 2 of them for PTT ( Push To Talk ) and the other 2 pins will end up being, one way or the other, connected to the mic element. Terrible sounding and probably will suffer from feedback. If you have a faulty cord, replace it immediately for smoother transmissions. Note on the XLR - for this application, on a DJ mixer and no phantom power involved, do connect pin 3 to pin 1 on the shield wire, meaning pin 2 will be only the center conductor of the mic cable.

SWR in this range is usually caused by a poor mounting location and/or a poor choice of equipment for your specific vehicle. When you turn the channel selector knob, the channel does not change. You cannot expect clear transmissions if you havent connected the power cable correctly. SWR 2.5 - 2.9: Performance in this range will be noticeably decreased, and you might even damage your radio if you transmit frequently and for extended periods. Secondly, ensure that any Antivirus software you are using excludes the microbit drive from being scanned automatically. The pin is called the mic gain, and its usually a small metal cylinder. But the drop from 1.5 to 1.0 won't make a substantial increase in performance. Simply put, you can only sound as good as your microphone allows. These systems often use shielded cables, making corrosion harder to detect visually. If thats ok, and the TX light does not lit, I`m almost sure your radio is not transmitting power out at all.
