Radio Martí is heard routinely on Cuba on AM on 1180 kHz, there are some funny situations that made that possible.
There is no secret on the long Cuba’s energy crisis, and as you may expect the local time 1700 (5pm) to 2100 (9pm) and some times up to 2300 (11pm) or later is the high demand period and they can’t supply the demand; then most of the country [but Havana, that is protected at all costs] got routinely blackout at that times.
As a result a few of the local AM transmitters get powered from diesel generators some times at reduced power; or usually just shut down altogether. Lately the AM transmitters are just powered off during the mentioned period and local diesel power is reserved for FM stations [also on reduced power].
So, almost every province has an AM transmitter on 1180 kHz to jam the Radio Martí one, but some AM listeners got a surprise when instead Radio Rebelde or a local station on the memory of his radio or they dial spot get Radio Martí, mind the surprise of the listeners.
Attached is a recording of right now, local Radio Rebelde Transmitter off and Radio Martí is coming strong, and here you have a picture of the SDR waterfall.
Receiver is a SDRplay with a 15m `long wire` connected to a 9:1 transformer for SW and MW monitoring, but you can pick it up decently with almost any AM radio, my PL-880 on local setting has no problem to hear Radio Martí on 1180 kHz most of the time.
So, with the blackouts they are turning off the jamming stations and at least in Camagüey Cuba it’s normal to hear it with battery operated radios.
