WREY (630 kHz, "94.9 El Rey") is a Spanish-language AM radio station with studios located in the Westside neighborhood in St. Paul.

The station's owners, the Tedesco brothers (Vic, Nick and Al), had previously launched WSHB in Stillwater, Minnesota, and attempted the following year to get into television on channel 17 but financial backing fell through.

WCOW was not very successful, so the station transitioned to a female-oriented format with the call sign WISK in 1957, and the frequency was changed to 630 kHz.

The Top 40 format of those stations was used to launch the new KDWB on October 1, 1959, with “Charlie Brown” by The Coasters being the first song played.

[6][7][8] Ratings for the country format did not meet expectations, and in September 1992, the station temporarily returned to a simulcast with KDWB.

[10] Borgen bought the silent WDGY in October 1996, and returned the station to the air in January 1997 as a Hudson, Wisconsin-based entity with the same call letters, airing a talk radio format that featured hosts like Don Imus, G. Gordon Liddy and Don and Mike, with oldies music from 6 PM to 6 AM.

A group of local Hispanic broadcasters had leased weekend time on WMIN for several years as "Radio Rey."

On January 1, 1998, WMIN went full-time Radio Rey, broadcasting from studios in a grocery store on the west side of St. Paul.

For most of 2005, WMIN ran a complementary Regional Mexican format, "La Nueva Ley," also programmed by the Radio Rey group.

WDGY eventually secured a transmitter site closer to the heart of the metro area, which allowed it to boost its power and change its city of license back to St. Paul by the end of 2005.

Subsequently, sister station WMIN, a True Oldies Channel affiliate at 740 AM, changed its call letters to WDGY.
