The longwave transmitter of the Nador facility, which works on 171 kHz, had originally a transmission power of 2000 kilowatts. After 2009 the original equipment had been replaced by a new set of Thomson Broadcast S7HP solid-state transmitters with an output of 1600 kW. This modernization project[4] incorporated a refurbishment of the three guyed masts, each 380 metres tall, thus the tallest structures in Africa after the demolition of the OMEGA Navigation System in Paynesville, Liberia in 2011.[5]

In addition the Nador facility is also equipped with two Thomson 250 kW shortwave transmitters.[6] One of these transmitters carried the main program of Morocco's state broadcaster SNRT on varying frequencies around 15345 kHz until it was switched off in September 2012.[7] The other transmitter was used for Medi 1 on 9575 kHz, unheard since May 2017 as well.[8]
