I ended up getting the achievement after mission redoing mission 7 but I never did end up finding the radio in mission 10 again. I did redo it a couple times before that though with no success. I tried tossing random nades in different areas but never did see the radio down pop up in the bottom left again. When I get a chance later tonight, I'll take another look.
