I would highly suggest replacing the DIN5 mike jack with a standard mike jack. I used the same jack as Icom uses for theirs in hopes of someday being able to use the Icom mobile mike rather than the Radio Slack mike. Radio Shack has the panel jack as part number TA-9104069. Now, has anyone tried to set up the DSP-10 for the Icom mike? Lee - AA1YN
