Many of the states lowest in percentage
covered are characterized by rugged terrain and low population
density outside of the cities.
Most major
metropolitan areas are served by more than one public radio
service.
The 1989 study identified
13 markets without public radio coverage. Of these,
12 are now reached by public radio. Many
are served by full power stations; others are covered by
signals from translators. Of the 13 markets identified
in the 1989 study without public radio coverage, only the
Laredo, TX, market remains unserved. The closest
public radio station is in Corpus Christi, approximately
130 miles away.
