The first radio station associated with the university broadcast unofficially in the 1930s, when it was the National School of Agriculture (ENA); another, "Radio 6.6 Chapinguito", broadcast from the university in the 1950s under the auspices of professor Hebert del Valle.
[3] More broadcasting efforts were discussed in the late 1970s and 1980s, but it would not be until 1989 that a group acquired a 30-watt transmitter and started the modern Radio Chapingo.
[5] On January 25, 2017, the Federal Telecommunications Institute approved the award of a new public concession to the university for XECHAP-AM 1130.
The new dial position was made available in the area when XETOL-AM in Toluca migrated to FM.
The new station broadcasts with 2,000 watts, less than before, but with increased population coverage compared to 1610.
