According to Arnie Coro at Radio Havana Cuba, the Cuban medium wave broadcaster Radio Progreso will begin an “experimental” shortwave broadcast on 4,765 kHz from 00:30 till 04:00 UTC on October 1st, 2013. For those of us living in North America, this broadcast will begin at 08:30 PM EDT tonight.
I will attempt to listen and record the broadcast tonight.
Many thanks to David Goren for the tip and for Bryan Mangawhai’s original report to DX lists.
