Hello Everyone,

...........

The manual didn't say anything about high pitched whistles, and I have
tried moving to different locations at home (i.e. where I got good
reception before), all to no avail.

Have you tried the radio several miles away from your house? If there
is no whistle away from home, then at least you know it is a noise
generated in your neighborhood.

Fortunately, it doesn't happen all the time during a sitting, so I just
turn the radio OFF, pause for a bit and then turn it back ON.

That works.... for a short while.

If there is no whistle when you turn the radio on, but then after a
short while it comes back, it sounds like the problem may be with the
radio.

Also, have you tried the radio with and without batteries? That would
tell you whether it is something coming over your AC power lines.
