How come I can pick you up perfectly fine one day and barely at all the next? |

WMJS-LP broadcasts on 102.1 MHz, the same frequency as WRXL in Richmond, VA and WIOQ in Philadelphia, PA. WRXL puts out 20,000 watts at 750 feet HAAT. WIOQ puts out 27,000 watts at 640 feet HAAT. Fortunately, the earth's curve puts those stations down below the horizon from Prince Frederick and they don't interfere with our signal in central Calvert County...normally. Certain weather conditions can mess things (and us) up! A warm front (warm air above cooler air) or a "temperature inversion" (cooler air trapped below a layer of warm air) will reflect FM signals back to earth or "duct" them for many miles, keeping the signals bent nearer the earth's surface instead of headed on a straight line off into space. When this happens, the two powerhouses on 102.1 to our north and south will be stronger than normal here and will capture your FM radio from our little 100-watt signal. Our reception circle then shrinks down tighter around Prince Frederick until the weather changes.
