Here in New Jersey we are fortunate to have a wide variety of radio stations that are public or college run.  These stations are mostly to the left of 92 on the dial, but there are exceptions.  As you can see, every corner of the public radio zone is filled with stations.  Some are from Pennsylvania, some from New York, and some from New Jersey.  On the AM dial, your choices are limited to AM 820 WNYC.   If you live in the center of New Jersey, you may be fortunate enough to get all of these stations on a clear night.
