The station broadcasts on AM and FM frequencies, XEUAS-AM 1150 and XHUAS-FM 96.1, in the state capital of Culiacán, and on an FM radio station, XHMSA-FM 102.9, in Los Mochis.
XEUAS-AM came on air for the first time on October 8, 1971, on 1330 kHz.
In 2008, the station upgraded to 60 kW effective radiated power, making it the most powerful FM radio station in Sinaloa.
On December 19, 2017, the Federal Telecommunications Institute cleared a backlog of radio station applications in the Los Mochis area, one of them belonging to the UAS for an FM radio station there, given the callsign XHMSA-FM and the frequency of 102.9 MHz.
The Los Mochis station will broadcast with 3,000 watts, though it is capable of 10,000.
