SOURCE: Motorola CLS 1450c radios microphone problem.

The problem you are experiencing is not a mic problem, or the problem would also be associated with the two-way radio portion of the radio. Your radio is either in need of repair or you have a bad, low or defective battery. It takes more energy to transmit or use the unit as a phone than to simply receive.

If your radio is under warranty (less than 1 yr old) you can return it to the place of purchase for warranty replacement or service. After warranty repair is also available through Motorola's factory depot. Ask your local dealer.

SOURCE: Kenwood tk-272g radio wont transmit

This is commonly a sign of a bad or poorly charged battery. Check your charger, battery and battery contacts. Clean contacts with a pencil eraser. Try recharging the battery, making certain the radio is turned off while on the charger. If this does not solve the problem, try swapping batteries with a known good unit. If the swapped battery solves the problem, you know you need to replace your battery and/or charger.

If the problem remains with the swapped battery, you know you have a radio problem. In this case, you will need to look at the battery contacts on the radio, where the battery meets the radio and see if you see a problem there. OR a problem with how the battery fits to or in the radio.

If it is a radio problem, you may need to see your local Kenwood dealer for assistance.

Best regards.

I have feedback when transmitting


Check your audio settings. Feedback is a condition caused when you are transmitting and your audio is coming out of a speaker (headphone) and is picked up by the microphone. Try turning your audio down; reducing your microphone gain; and perhaps using a wind sock (microphone cover) over your microphone to reduce the amount of feedback audio entering into the microphone (manual pg 13).

Trying to determine the cause of intermittent signal from microphone on a vx 4600 radio


Yes, short or lack of a good ground. It could also be the cord attached to the mic. The mic itself should provide the needed feedback to the radio that a mic is plugged in. Do you have anything connected to the accessory jack in the back of the radio? That can cause the same issue.

hello there,
Well you have not supplied much information-------- How ever I will give it ago, it seems as if you have a microphone problem. If you have two such radios do the Microphones unplug from the actual Radio, if so interchange them and see if the other Radio produces the same sympton then it's probable it is in the Microphone! If you cannot exchange microphone as I suggest I am afraid it will need servicing by some one confident to carry it out.
Best of luck,
John
