## History

### XEDF-AM

1500 AM began its life in the 1970s. Its original [call sign](/source/Call_sign) was XERH-AM. It called itself "La Tropical Grande de México" with [tropical music](/source/Tropical_music).[8] In the 1980s, it became XEAI-AM (call letters now on 1470 AM). It adopted several formats, such as tropical music and general music. In 1998, the [oldies](/source/Oldies) "Vida" format at 1470 AM, then known as XESM-AM, was moved to 1500.

It was not until 2000 that 1500 AM was renamed XEDF-AM. It became a news/talk station as part of Radio Fórmula's second national talk network, "Segunda Cadena."

### XEDF-FM

The station [signed on](/source/Sign-on) the air in 1984. It was known as "Jazz FM", a station remembered as a milestone in the history of jazz in Mexico. Despite praise for a format not otherwise available on Mexican radio, the ratings were not sustainable.

In 1992, XEDF-FM became [tropical](/source/Tropical_music)-formatted Radio Uno, attempting to compete with [XEQ-FM](/source/XEQ-FM) 92.9 "Tropi-Q" and [XHFO-FM](/source/XHFO-FM) 92.1 "La Z". During this era Radio Uno was considered an important station in the promotion of new subgenres of [cumbia](/source/Cumbia_music) as well as [grupera](/source/Grupera) music.[9] After eight years, management decided to end music on the station.

In 2000, XEDF-FM became the keystone of Radio Fórmula's Segunda Cadena (or Cadena Radio Uno, as it was known for a time). It began broadcasting a news and talk format different from the original Radio Fórmula feed.
