SDR recording catch, on 1620.008 kHz from 2300-0026 UTC per the high resolution Carrier Sleuth Waterfall. A much weaker carrier than the MoR pirate that turns up on 1620.010 kHz. So I am not sure if this is a different station, or the same one and just weaker and slightly off frequency tonight.
Weak music heard under Cuba around 0020 UTC.
