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.
ECM (MICROPHONE ELEMENT) PART# T91-0393-08
This is an optional change that is not covered under warranty.
Time required to replace the ECM is 1 hour or less.
