Licensed to RCRQ, Inc.—a company owned by veteran broadcaster John Garabedian —the station plays a mix of adult standards and soft oldies music from the early 1990s and earlier.

In 1976, the Harvard Crimson wrote: "The least pretentious station around is WCAS at 740 AM, which mixes country, soft rock, and folk nicely, and goes easy on the ads.

It paired local acts with national headliners at Passim's coffeehouse such as Ry Cooder, Tom Waits and Jimmy Buffett (the latter two then relatively obscure).

One of these, "Somerville",[5] was a satirical comment on that local city, written by David Misch, who later wrote for the TV shows Mork and Mindy and Saturday Night Live.

However, in both of those situations, there was a loud public outcry which disrupted the sales, and enabled WCAS to last as long as it did—singer David Misch played a key role in organizing these.

WCAS finally went under in early 1981; the rest of the 1980s saw a revolving door of owners, call letters, and formats, eventually becoming black gospel station WLVG ("We Love God").

In the summer of 1991, Bob Bittner purchased WLVG, and changed the station's format to "Earth Radio" (a blend of contemporary music with environmentally-aware public service spots) under the call letters WWEA.

[9] In January 2024, Bittner's estate announced that John Garabedian—broadcaster and former host of the syndicated radio show Open House Party—would acquire WJIB and translator W267CE.

Bittner specified that donations should be personal checks; no credit cards would be accepted, since doing so would direct fees to lenders who encourage America's mass indebtedness.

In ensuing years, Bittner conducted similar annual fundraising drives, and thanks to loyal listeners, he was able to raise the money to keep the station on the air.

In addition to listener donations, some Sunday-morning programming time was sold to local churches and religious organizations, which added to the station's revenue.
