If only Moses could part the airwaves too.

South Brooklyn listeners of the Big Apple’s only classical radio station are livid that a pirate broadcast of a man preaching the Torah often drowns out their Tchaikovsky.

The irked orchestra fans lodged several complaints to WQXR (105.9 FM), which recently reported the pirate broadcasts to the Federal Communications Commission.

But the religious screeds are still spoiling the station’s soft crescendos.

“It’s my favorite radio station and I can’t even listen to it anymore. It’s gotten so bad,” said Kensington resident Patrick Russell, 65.

About a month ago, “I was reading and trying to unwind listening to WQXR when suddenly I started to hear this crackling and a weird voice,” Russell recalled. “I was like what the hell is this? Then I turned the dial and boom!”

The illegal airwave — located very close to the classical station’s frequency, at 105.7 FM — features religious tunes, but is mostly a man “yelling and lecturing about the Torah” in English and Hebrew, Russell said.

The FCC confirmed that “there is no licensed operation on that frequency in New York City,” said spokeswoman Margo Davenport.

The illicit station chiefly affects Kensington, Windsor Terrace and Park Slope, and hijacks the frequency from about 6 p.m. until 8 a.m., Russell said.

“I like classical music to wake me up in the morning nicely. I don’t want somebody screaming at me,” Russell added. “Same for when I’m going to bed.”

Kensington resident Julie Semkow, 73, is also shielding her ears.

“The override has been driving me crazy,” she said. “I wish I had my favorite station back.”

WQXR said there have been “several complaints” about 105.7 “bleeding into” their station,” according to spokeswoman Jennifer Houlihan Roussel. The identity of the rogue broadcaster remains unknown.

But it’s not just the classics that are being robbed of their sound, said Jayjayel Whycee in a closed Kensington Facebook group.

“I get interference from them all the way from 104.3 to 106.7,” he wrote.

Pirate stations are a big problem in the city (especially in Brooklyn) with about 100 operating illegally throughout all five boroughs — up 58 percent this year compared to last, according to New York State Broadcaster’s Association president David Donovan.

“Illegal radio operations are not like the movies — the rock ’n’ roll ship off shore. They are a real problem transmitting from rooftops across New York City,” Donovan said.

The stations “pose a direct danger” to human safety by interfering with the Emergency Alert System, airplane frequencies and do not comply with the FCC’s radiation rules, Donovan said.
