Dave Plotkin (search) rocked around the clock — several times over.

The disc jockey at Rollins College's (search) WPRK-FM unofficially set a record Friday for the world's longest continuous broadcast by a single DJ.

Plotkin, 25, took to the airwaves at 9 a.m. Monday and signed off at 11:03 p.m. Friday, a 110-hour span. A DJ in Switzerland lasted 105 hours in July 2002.

"Everthing I did, every facet of my life for the past five days, I was broadcasting on the radio with a wireless (microphone) or here in the studio," Plotkin said Friday evening in the seconds before reaching Hour 106 and breaking the old record. "I miss the outside world."

The event, planned for more than a year, raised $16,150 for the 52-year-old radio station.

It will take Guinness (search), keeper of the world's records, four to six weeks to validate Plotkin's feat.

Under Guinness' rules, Plotkin had to speak at least once every 59 seconds. And there was no napping while "In-A-Gadda-Da-Vida" played: Songs could not be longer than six minutes.

The event, planned for more than a year, raised funds for the station. The broadcast, which also went out over the Internet, drew donations from as far as Peru.

In between spinning CDs from indie rockers, Plotkin hosted local bands, interviewed artists and civic leaders, gave interviews himself and took cold showers in a stall built down the hall from the studio.

He was watched by medical professionals, journalists, friends, family and assorted well-wishers in what turned into the small liberal-arts college's social event of the season.

"Since you've been down here in this hole of hell for so long," said a woman offering Plotkin a purple orchid, "I thought you needed something alive and beautiful."

Others seemed to be drawn by the curious sight of a man determined to stay awake for close to five days straight. Toward the end he tried to put CDs into closed trays, banged his head on the microphone and forgot his station's call letters.

"I'm a lab rat," said Plotkin, his face unshaven and his eyes fading in and out of glassiness.
