Radio Máxima, Managua, on 660 kHz, which is not included in mwlist.org and listed as ‘off air’ in WRTH 2022 is indeed still broadcasting. The official schedule is daily at 1200-1600 UTC. However sign on is often as late as 1245, and often the transmitter is kept on the air long after 1600 UTC into the local afternoons. The station mostly identifies as “Stereo Caliente 89.3 FM” – but Radio Máxima station ID’s are also heard.
