The Universal Device Connector (UDC) provides connections for external accessories such as a headset, 
a speaker-microphone, audio test box, audio test cables, and programming cables.  The UDC is located on 
the right side of the radio, opposite the PTT Button.  The UDC facilitates programming and testing the
