Analog-to-digital conversion

WJMN signed on its digital signal on UHF channel 48 in 2002; originally, this signal operated at a very low-power from a transmitter west of Downtown Escanaba and was only available in the immediate area. A construction permit in July 2009 allowed the station to increase its power to 1 megawatt and move the digital signal back to its analog transmitter site. However, according to an engineer, this would not happen until sometime in 2010. Therefore, the updated digital signal of 9.8 kilowatts still could only be received in the immediate Escanaba and Gladstone areas.
