They primarily serve areas of southern New Jersey not covered by the main WHYY-FM signal, which itself operates at a relatively modest 13,500 watts. However, their combined footprint extends WHYY-FM's coverage from Berks County to the Jersey Shore . In November 2022, WHYY began to reduce its New Jersey radio footprint by announcing that it would sell WNJB-FM to non-profit Christian Broadcast, The Bridge of Hope, Inc., which owns WKNZ in Harrington, Delaware. The sale

By convention, these are typically not expressed in hertz, but in terms of the equivalent energy, which is proportional to the frequency by the factor of the Planck constant . The CJK Compatibility block in Unicode contains characters for common SI units for frequency. These are intended for compatibility with East Asian character encodings, and not for use in new documents (which would be expected to use Latin letters, e.g. "MHz").

After WFLN's new owners also abandoned the classical format in the late 1990s, Temple University 's WRTI (90.1 FM) began programming classical music during the day to serve the displaced listeners. On June 6, 2011, the New Jersey Public Broadcasting Authority agreed to sell five FM stations in Southern New Jersey to WHYY. The purchase

The correspondence between a frequency f with the unit hertz and an angular velocity ω with the unit radians per second is The hertz is named after Heinrich Hertz . As with every SI unit named for a person, its symbol starts with an upper case letter (Hz), but when written in full, it follows
1886-490: Was adopted by the General Conference on Weights and Measures (CGPM) ( Conférence générale des poids et mesures ) in 1960, replacing the previous name for the unit, "cycles per second" (cps), along with its related multiples, primarily "kilocycles per second" (kc/s) and "megacycles per second" (Mc/s), and occasionally "kilomegacycles per second" (kMc/s). The term "cycles per second" was largely replaced by "hertz" by

WHYY assumed control of the stations through a management agreement on July 1, 2011, pending FCC approval for the acquisition. At that point, the stations began to simulcast WHYY-FM programming. The five stations are: Download coordinates as: The stations all operate at relatively low power due to

The five stations were previously the southern portion of the New Jersey Network 's statewide radio service. The transaction was announced by Governor Chris Christie , as part of his long-term goal to end state-subsidized public broadcasting. The governor's critics maintained that scrapping New Jersey Network effectively ended all non-commercial statewide news coverage. It
2116-555: Was named after the English county in which William Penn 's family home lay, Berkshire , which is often abbreviated to Berks. Berks County began much larger than it is today. The northwestern parts of the county went to the founding of Northumberland County in 1772 and Schuylkill County in 1811, when it reached its current size. In 2005, Berks County was added to the Delaware Valley Planning Area due to
