The station broadcasts at 830 AM at a transmitter power output of 50,000 watts and can be heard from Maine to Providence, Rhode Island, and from Boston to Springfield, Massachusetts (during the day). The signal is directional, pointed away from such other stations at 830 kHz as WCCO in Minneapolis, Minnesota. After sunset, WCRN's signal is made further directional towards the east; as a result, it is not clearly audible in Western Massachusetts after sunset.
The station bills itself as "Full Service", with a talk radio format all day, except for financial shows from 9-11 a.m. and noon to 1 p.m. weekdays and infomercials at assorted times on Saturdays and Sundays. The station simulcasts news from WFXT (channel 25) in mornings. WCRN runs music of the 60s, 70s, and 80s at night as North Star Music.
WCRN signed on December 5, 1994, carrying religious programming from the Carter Radio Network, based out of then-sister station WROL in Boston. In December 2000, this was abandoned in favor of a big band format, "Swing 830". The format was changed to oldies, via ABC Radio's The True Oldies Channel, in August 2004, and then to the current talk format on May 8, 2006.
In 2000, the station was allowed to increase its daytime power from 5,000 watts to the current 50,000 watts. Nighttime power was also increased from 5,000 watts to 50,000 watts on April 4, 2007, just in time for the first Boston Red Sox night game of the season.
WCRN's programming features the following programs:
- Weekdays: Boston 25 Morning News, The Howie Carr Show, and Doug Stephan.
- Weekends: Progressive talk from Jeff Santos, sports, programming from Talk Radio Network and Radio America, and The Twilight Zone Radio Dramas.
Weekend political talk on the weekends includes Conservatively Speaking hosted by Mike Wade on Saturdays from 6:00 am until 9:00 and All Politics is Local in Massachusetts hosted by Jon Fetherston and Terry Hendrix Sunday's from 10 am until noon. Featuring national, state and local elected officials and how all political decisions effect local communities. WCRN was the flagship for the Worcester Tornadoes minor-league baseball team during the 2005 and 2010 seasons. The station is also an affiliate of the University of Massachusetts Amherst network for football and men's basketball broadcasts.
From 2007 through 2009, and since 2011, WCRN has shared the Worcester affiliation of the Boston Red Sox radio network with WEEI/WEEI-FM satellite station WVEI, an arrangement made in order to take advantage of WCRN's then-new 50,000 watt night signal to serve areas of MetroWest that had difficulty receiving either WVEI itself or the team's then-flagship, WRKO, particularly at night (when most Red Sox games are played), with WVEI selling local advertising on both stations. The two stations replaced WTAG, which had carried Sox games for 40 years. WVEI became the sole Red Sox affiliate in Worcester in 2010, but WCRN returned to the Red Sox network in 2011.
