How to get radio sound clips?

I’m doing this project that explores the relationship between radio and politics in Angola, both during the time of the revolution and in present day.
Part of this project involves the usage of clips from the modern day station, “Radio Despertar”. I am particularly interested in the broadcasts of Alberto Chakusanga, who was assassinated in September of this year.
The problem is, I have no idea how to access this source on the web. I’ve found some sites that look promising, but once I navigate to them, they freak out…also, many of them are in Portuguese, which I unfortunately do not speak.
Is there anyone out there in the Fluther community who can help, pretty please?
