The 800 kHz frequency in Lawrence first
signed on the air in August 1947. Its
call sign was WCCM and it was owned by Lawrence Broadcasting Company. An FM sister station, WGHJ at 93.7 MHz (today
WEEI-FM) was launched in April 1960 as a full-time
simulcast of WCCM. In 1963, WCCM and WGHJ were sold to sportscaster
Curt Gowdy, who changed WGHJ's call letters to WCCM-FM that year. Both stations carried a
full service middle of the road music format. In 1974, the simulcast ended. The FM station became WCGY, first airing a
Top 40 format and later switching to
album rock. WCCM continued on AM 800, with some
talk and Spanish programming. However, a buyer was not found until 1997, when the Costa-Eagle partnership agreed to purchase the station. Soon after taking over a year later, Costa-Eagle shifted the station from adult standards to full service
adult contemporary. The following year, WCCM began marketing itself to the
Lowell area, after
WLLH (1400 AM) was sold and converted to Spanish-language programming. WCCM opened a Lowell studio and hired several former WLLH personalities including news anchor Bob Ellis. It began carrying
Lowell Spinners baseball, which had previously aired on WLLH. WCCM also began shifting back to standards, replacing satellite talk programming from Talk America with the
Music of Your Life network a few months later. The Lowell studio was closed in 2002 after the station gradually phased out its use. WCCM also ended out much of its music programming, with local talk shows during the day and
sports radio programming from
ESPN Radio during evenings, nights, and weekends. The station was assigned the WNNW call letters on August 29, 2002. It was part of a larger shuffle that resulted in WNNW moving its
Spanish tropical format from
1110 AM,
WCCM moving to 1490 AM, and the programming of WHAV (1490 AM) moving to 1110 AM as WCEC. The changes formally took effect on-air that September. In 2008, owner Pat Costa received
Radio Ink Magazine's Medallas de Cortez Award for General Manager of the Year. Later that year, Costa-Eagle purchased W275BH, a
construction permit for an FM
translator at 102.9 MHz in
Newton, New Hampshire. Costa-Eagle moved it to 92.1 FM in Lawrence in 2009 (thereby changing its call letters to W221CH). It signed on that March as a
simulcast of WNNW. In June 2011, the translator was moved to 102.9 FM (reclaiming the W275BH callsign) due to interference complaints from
WFEX in
Derry, New Hampshire, and
WPHX-FM in
Sanford, Maine. ==Translators==
