[4][5] WHEB is the home of regional comedy radio show, The Morning Buzz, hosted by Greg Kretschmar.

In 1947, construction began on an FM station that could also provide nighttime service, WFMI on 97.3 MHz, licensed to Portsmouth, but with a remote transmitter site located atop the middle peak of Saddleback Mountain.

This in turn reduced the value and revenues of advertising, and when WFMI contracted sponsorship for a basketball tournament in March 1949, it was only able to charge 20 percent of the standard rate paid for WHEB.

[12] The economics for FM stations had somewhat improved in the early 1960s, and Knight Broadcasting of New Hampshire started to make plans to return to the band.

In March 1962, a fire destroyed the WHEB (AM) studios,[13] and a year later operations moved into a newly built facility.

Assigned the call sign WHEB-FM, it began broadcasting on January 14, 1964, with a reported 60% duplication of programming of the AM station.

In the early 1980s, WHEB-FM got an ERP boost to 31,000 watts, coupled with its own separate programming, a Top 40 format.

In 1991, Knight Broadcasting decided the AM station was no longer needed, and was shut down, and the license handed in to the Federal Communications Commission for deletion.
