Earlier this week, I noted that Cuban medium wave station, Radio Progreso, was to begin broadcasting on 4,765 kHz shortwave, beginning October 1st at 00:30 UTC.
I listened between 00:30 and 2:30 UTC on Oct 1st, but heard nothing other than the weak carrier from (possibly) Radio Emissora De Educao Rural. However, the following evening at 01:00 UTC (October 2nd) I did hear a strong signal from Radio Progreso.
For your listening pleasure: the recording I made of Radio Progreso on October 2, 2013, starting around 01:00 UTC. Click here to download the recording as an MP3 or simply listen via the embedded player below:
