The owners of WJJB, a Portland sports talk radio station known as the Big Jab, will begin simulcasting Boston sports talk station WEEI in southern Maine on Sept. 1.

WJJB's owner, Atlantic Coast Radio, has finalized a contract to simulcast WEEI through 2013, said Jon Van Hoogenstyn, general manager of WJJB. Jim Rushton, vice president of sales for Entercom New England, confirmed that the contract had been finalized. Entercom owns WEEI.

Rushton said the announcement of the contract is very different than the announcement made last summer, when Nassau Broadcasting declared its intent to simulcast WEEI in Portland.

At that time, Entercom and Nassau had signed a letter of intent, said Rushton, but the contract was not finalized and the simulcasting never happened. But Entercom and WJJB have a signed contract.

WEEI will be heard in southern Maine at two dial positions, said Van Hoogenstyn. One is 95.5 FM, currently the FM home of WJJB. The other is 95.9 FM, currently a hip hop station owned by Atlantic Coast Radio, WRED. Van Hoogenstyn said the hip hop station will go off the air.

WJJB's programming - which includes eight hours of local talk shows, syndicated shows, and Boston Red Sox games - will remain in tact and will continue to be broadcast on 1440 AM.

The station's FM signal will be heard on 96.3 FM, which is currently the FM signal of Atlantic Coast's news talk station WLOB. Van Hoogenstyn said WLOB will still be heard at 1310 AM, but will not have an FM signal.
