National religious leaders heard on WHAZ include Jim Daly, Charles Stanley, Joyce Meyer, Chuck Swindoll and David Jeremiah.

[4] WHAZ's first license, for both broadcasting wavelengths, was issued on July 18, 1922, to the Rensselaer Polytechnic Institute (RPI) in Troy, New York.

[6] Later that month the Department of Commerce set aside a second entertainment wavelength, 400 meters (750 kHz) for "Class B" stations that had quality equipment and programming.

[12] On November 11, 1928, as part of a nationwide implementation of the provisions of the Federal Radio Commission's General Order 40, WHAZ was assigned to 1300 kHz in an historic four-way timeshare with three stations in New York City-area: The Jewish Daily Forward's WEVD, the Watchtower Bible and Tract Society's WBBR and the Defenders of the Truth Association's WHAP.

[14] WHAZ continued to share time with WEVD and WBBR, and in March 1941, implementation of the North American Regional Broadcasting Agreement resulted in the three stations moving to 1330 kHz.

[15] In 1965 RPI attempted to sell WHAZ in two parts, with the station's daytime hours going to the Troy Record Company for $15,000, and its nighttime allocation, which was Monday nights from 6 p.m. to midnight, being transferred to WEVD for $50,000.

However, WPOW, successor to WBBR, successfully blocked the sale, on the grounds that it needed to approve any changes in the timesharing agreement.
