Transmission problems at Montreal's Haitian radio station are forcing it off the air on weekdays, because its signal interferes with a neighbour's phone system.

Since the end of September, CPAM has not been able to broadcast its programming weekdays between 7 a.m. and 6 p.m.

CPAM host Henry Salgado said the problem is temporary and caused by the location of the station's transmitter, which was recently moved.

The limited broadcast time has caused a 20 per cent drop in ad revenues for the station over the past few weeks.

And more importantly, said Salgado, it has silenced a valuable resource Haitian Montrealers rely on.

"This is a big problem for the Haitian community," he said.

Station manager Jean Ernest Pierre said the community depends on CPAM for the latest news from Haiti.

"We have a lot of problems in Haiti and we have to know the news of the day, the music, the culture, all of it," he said. "For some people, it's the continuation of Haiti here in Montreal."

Pierre said the problem should be resolved by next spring, when a plan to share an antenna with the CJMS radio station in the Montérégie region goes into effect.

In the meantime, the station is in talks with its neighbour's phone provider, Telus, to come to a short-term compromise.

The business owner next-door to CPAM told CBC News that Telus will begin setting up a new phone line for them on Friday.
