Check out this news by Sheldon Harvey of The International Radio Report:
As reported by many DXers worldwide, Radio Guinée, from the Republic of Guinea in west Africa has returned to shortwave on 9650 kHz. Check between 0000 and 0300 UTC as well as around 0600 UTC. Programming is in French with lots of African music. Here is an article from March about the state of radio and TV transmitters in the Republic of Guinea. Perhaps this is what spurred them to reactivate the shortwave transmission. The article is in French.
Thanks for the heads-up, Sheldon! I start listening for Radio Guinée again.
