Sermons on radio in Africa

So many sermons on Sermonindex are life-changing. A lot of people in Africa can benefit from them. The internet is still out of reach for many Africans - radio is more accessible.

So, featuring sermons on the radio can be a huge ministry to English-speaking Africans.

I'm going to start exploring with some radio stations in African countries about airing sermons.

Does anyone have experience in this? Any advice that might be helpful?

Thanks.
