History

Single-frequency network

UAM Radio originally broadcast on 94.1 FM from five 20-watt transmitters at various UAM facilities, each of which is located at a different UAM facility in Mexico City:

The XHUAMR-FM transmitter

It is estimated that the transmitter network covered 70% of Mexico City.[2]

The permits for these stations were awarded by Cofetel on January 27, 2010. The network signed on March 11, 2011, bringing the 94.1 FM frequency back to use in Mexico City for the first time since the closure of XHFM-FM in 1957.

Conversion to a single transmitter

In July 2017, the Federal Telecommunications Institute authorized UAM Radio to begin using one transmitter, from the Cuajimalpa site, using the callsign XHUAM-FM and with a power increase to 3,000 watts, expanding reception to eastern portions of the State of Mexico. The university sought the change because its single-frequency network was "not sufficient to provide an efficient FM radio service to Mexico City".[3]

Testing began for the higher-power transmissions from Cuajimalpa in March 2018.

Format

The format is largely cultural in nature. Some programs utilize UAM resources and are produced by departments at the various UAM units.

gollark: Just split it into two right angled triangles. Easy.
gollark: So it's 1/10 * 1/10 = 1/100.
gollark: The probability of two independent events both occurring is the probabilities of each multiplied together.
gollark: I think the axioms are satisfied fine if you just remove all numbers except 0.
gollark: `(= (lim x 0 (/x x)) 1)` ← definitely very* readable and certainly much easier to parse.
