Owned by Cynthia Citlalick Cano, through licensee Cano's Broadcasting, LLC, WMJH broadcasts with 3,600 watts of power during the day, which, along with its lower dial position, allows it to be heard as far north as Kalkaska, Michigan, as far east as Redford, Michigan, as far south as Three Rivers, Michigan but must sign off at night to protect WGY in Schenectady, New York.

In 1996 the stations calls were changed again and from 1996 to 2004, WMJH was known as "Magic 810," airing a satellite-fed Adult Standards format from Westwood One.

"Magic 810," which also broadcast in AM stereo for a time, had a loyal audience and respectable ratings for an AM daytimer, but was chiefly popular with listeners aged 55 and older, which led Birach to switch the station's format to brokered Spanish programming, under the name "La Poderosa" (Spanish for "the powerful one") using the slogan "Con Sentimiento Mexicano".

On November 7, 2008, the "La Poderosa" programming and format moved to WMFN AM 640, after that station's prior lessee, Tyrone Bynum, vacated the station, which, at that point, WMJH retooled its format to lean more towards Spanish-language Adult Contemporary.
