Get a complete manual for your VHF radio. An older VHF with transmission problems usually has a connector problem, so check all the connections on the back of the radio. Then look at the microphone’s connection to the radio. If it is a plug-in, get into the plug on the end of the mike. Look for a broken solder joint to one of the pins. Look at the transmit pins carefully. If one is broken, solder it on, or take it to a local electronics repair house.
If the mike is not the problem, look at the connector inside the radio, and do the same thing: Check the soldering of the connectors. It is likely you will have found your problem and fixed it at this point.
