I have a Uniden 510XL that I would like to use to listen without the mic
attached. When I unplug the mic I get no audio. I rarely talk and
don't have much room in my car so I would like to leave the mic
unplugged unless I am using it.

Anyone have an idea of a way to trick the radio into thinking the mic is
attached? Or maybe another small (and cheap) CB that doesn't need the
mic attached?

Thanks.
