Lotsa new peeps.  Welcome.  Not sure on that one.  I always remove the the antennas, thats whats funny.  I dont recall that design, as all of them that I can think of were on the outside under the side plastic.  Did you remove the plastics to see if it continues?  When all else fails...break it, thats what I usually do.  Err, you could continue searching the internet or you could get lucky and one of our members could answer your question instead of blabbing continuously as I am doing right.....uh, now.
