BULLETIN # 958
MODEL: MC-44DM
SUBJECT: MC-44DM Microphone Audio Improvements

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.

Inside the microphone, there is a felt pad lightly glued to the microphone 
element housing. Removing the pad will increase the audio level.

If more level is desired, the microphone element can be changed to a 
more sensitive element. The element can be ordered through Kenwood's Parts 
Distributors.
