The BNC connector on the top of my KX-99 has become very slightly
loose. Does anyone know how dangerous it is to open the case up and
try to tighten it? I assume it has a nut of some sort. I just don't
know how much has to be removed to get to it.

The radio has been great. It has worked perfectly since I bought it
new maybe 15 years ago. I don't want to mess it up.

Thanks

Kurt
