A month ago a new FM Radio station was launched in our city. Since
that time my car radio (2 years old) had been hijacked. Whenever I
pick another station it plays for a split second then the radio scans
to the new station. Can you tell me what it going on and what I can
do about it?

Perhaps this is what's causing your problem?

Drivers don't have to adjust their car's radio dial, because some Des
Moines stations are changing themselves.

A new digital signal is causing a few glitches for some car radios.

The problem started a few weeks ago. Fans of 93.3 FM and 102.5 FM
noticed their radio station presets would sometimes refuse to stay on
the right station.

Drivers would find that when they push their preset button that is set
to 93.3 FM, it stays for a second and then switches back to 102.5 FM
by itself.

GM and Chrysler dealers are trying to repair car radios in Des Moines.

It turns out it's not the radio, it's the signal.

Des Moines Radio Group, which owns the two stations, just began
broadcasting a digital signal.

In some newer cars, that signal will tell drivers what song is playing
and the artist. It's that signal that is confusing some radios.

"There are always quirks and growing pains with new technology, but
this is the strangest I've seen," said Joe Farrington, chief engineer
of the Des Moines Radio Group.

The radio station said it is aware of the problem and will replace
some equipment will have it fixed in a month or so.
