There are several ways to increase the transmit audio level when using an MC-44DM. If you are using a single band transceiver such as the TM-231A, you can turn up the deviation control inside the transceiver. Do not turn up the deviation controls in dual banders such as the TM-731A because the audio will distort during repeater cross band operations.
