Hence the move of Italian programming to AM 1540. By the way, the call letters CHIN are a reference to the Italian language. CHIN-AM-FM were originally both Italian and the studios are in the Palmerston-Little Italy section of Toronto. But over time, Italian programming has taken up less time each week.
Here are the stations...
1540 CHIN ... 50,000 watts days - 30,000 watts nights. Directional antenna at all times.
100.3 CHIN-FM ... 8,500 watts - 13,800 feet.
91.9 CHIN-1-FM ... 1,760 watts / 5,000 watts max - 280 feet.
CHIN-1-FM used to be a translator for the AM station. But CHIN got it made into its own low-power station. I don't think this would be possible in the U.S.
