*Brian McKnight’s three-year-old morning radio show in Los Angeles has come to an end. The R&B singer is scheduled to announce his departure from KTWV-FM “The Wave” during his 6-9 air shift this morning, reports the LA Times.

McKnight’s busy schedule, which forces him to prerecord some segments for KTWV, played a part in the station’s decision to let him go, according to the Times. The multi-platinum R&B star has also hosted his own TV show, a syndicated radio show, still performs live and is writing a book. Station managers now prefer a live and local host in the time slot.

“I have thoroughly enjoyed my time the last three years. I love the one-on-one with the fans,” McKnight told The Times, but “it seemed like a good time to get out.”

Friday will be McKnight’s last day. Taking over on Monday (May 17) will be Kim Amidon, who for 22 years co-hosted mornings at adult-contemporary station KOST-FM (103.5), until the station replaced her in November 2007. She’ll join co-host and producer Pat Prescott, who has been on mornings at KTWV, better known as “The Wave,” since 2001.

Although listeners might miss McKnight, Prescott said she’s certain they can understand his scheduling constraints.

“I really feel fortunate to have had these three years working with Brian,” she said. “This is the first radio show he ever did, and he took to it so naturally.”
