WQXR-FM has less range and population coverage on 105.9 than it had with its old signal on 96.3. WQXR-FM's old and new signals both radiate from the same FM master antenna atop the Empire State Building; but while WQXR-FM's old signal is 6,000 watts ERP (effective radiated power—the energy concentrated toward the horizon), its current signal is 610 watts. The calculated signal strength of the current signal at 30 miles (covering about 14.5 million people) is less than the previous 96.3 FM signal at 42 miles (covering about 17.1 million people). Further compromising coverage is Hartford's WHCN, which also broadcasts on 105.9 MHz. While WHCN has a directional signal with reduced wattage toward WQXR's transmitter, the two stations do interfere with each other where their signals overlap.
