I picked up a Sony portable shortwave receiver at a garage sale, and it
has a peculiar problem.  WHen I first turn it on, it is *silent*.  Then,
over a period of several minutes, the volume comes up to audible levels.
If I bump the antenna, or do anything else that makes a big noise spike,
it goes silent again, to come back a few minutes later.

Any ideas?

Email preferred; I'll summarize.
