Check the RF output transistor, usually heatsinked to the inner chassis, microphone wiring needs to be checked for breaks since it is part of the circuit, sub another if possible.

Bad or incorrectly wired mic (broken wires in mic or cable) OR transmit circuit has failed.

Someone with a Dummy load/watt meter can test this safely.
