In Mexico's listing Radio Fórmula 103.3 (CDMX) lands at 34 of 444, which puts it on the first or second page of the country hub rather than in its tail.
Radio Fórmula 103.3 (CDMX) broadcasts in Spanish, which is the language most of Mexico's stations in the directory use. The country's listing records six languages in total, so the Spanish stations are the body of the dial rather than the whole of it.
103.3 fm is the station's own leading tag and no other entry in Mexico uses it that way. Worth reading as self-description: the directory takes tags as broadcasters type them and does not reconcile them.
Encoded as AAC, one of the three formats Mexico's stations use. The country page breaks all of them out with counts.
Radio Fórmula 103.3 (CDMX) publishes an HLS stream. That is a modern and perfectly good way to broadcast, and it is also why the button on this page may not start it: HLS needs a player that can read a playlist and fetch segments, which a browser audio tag does not do on its own.
The stream address on this entry points at mdstrm.com, which is where 23 other stations in Mexico are served from as well. Platforms of that size carry the long tail of a country's dial, and they are the reason a listing can look broken when it is one host having a quiet hour.

Radio Fórmula 103.3 (CDMX) is one of 1,290 playable stations the catalogue lists in Mexico, and one of the smaller number that say where in the country they transmit from.
These are counts of what people did inside the public radio-browser catalogue and the apps that read it, over the whole life of the entry. They are not our own figures and they are not an audience measurement: most entries in this catalogue sit under five all-time plays, so a small number here means the catalogue has little to say about this station rather than that nobody listens to it.
Broadcast by Radio Fórmula 103.3 (CDMX). Stream served directly by the broadcaster. Their own site is at www.iheart.com.
Listed in the directory as Radio Fórmula 103.3 (CDMX) - 103.3 FM - XERFR-FM - Grupo Fórmula - Ciudad de México. The heading above is that entry with the web address, the trailing keyword list and the block capitals taken out of it, which is a change to the spelling and to nothing else.
Station details come from the public radio-browser directory and are reproduced as recorded there. If you run this station and something here is wrong, or you would rather the page did not exist, write to us from the support page and we will fix or remove it.
