WFMB features local hosts in morning and afternoon drive time, plus agricultural reports weekdays at 5:30 a.m. and noon.

WCBS was originally a portable broadcasting station, assigned to Harold L. Dewing and Charles H. Messter of Providence, Rhode Island.

They were commonly hired out for a few weeks at a time to theaters located in small towns that did not have their own radio stations, to be used for special programs broadcast to the local community.

Regulating "moving targets" proved difficult, so in May 1928 the Federal Radio Commission (FRC) announced it was ending the licensing of portable facilities,[6] and WCBR was deleted in the summer of 1928.

[1] The FRC also informed stations that if they wanted to continue operating, they needed to file a formal license application by January 15, 1928, as the first step in determining whether they met the new "public interest, convenience, or necessity" standard.

[12] On May 25, 1928, the FRC issued General Order 32, which notified 164 stations, including WCBS, that "From an examination of your application for future license it does not find that public interest, convenience, or necessity would be served by granting it.

[1] Its frequency was changed to 1450 kHz in March 1941, as a result of the North American Regional Broadcasting Agreement.

[33] The station still operates from an historic radio tower in suburban Springfield, IL (Southern View), which was constructed in the late 1940s, and was the original transmitter location for WICS TV 20.
