Another trick, depending on how the swivel is constructed, would be to
take a hammer and smash the radio to bits...... hold on, too much coffee
this morning.

Take that hammer, and maybe a nail, brace the swivel against a solid
object, and tap the other side until the swivel stiffens up a bit. It's
a temporary improvement, as the swivel will loosen again over time, but
if it's loosened anyhow, it doesn't make much difference.

Safer to use a BIG pair of pliers (with lots of leverage) and squeeze it
hard.
Hammers and electronics inside plastic are something I try to avoid. :-)
