Broadcast Audio Transcript:
"This is Radio Kudirat Nigeria, the voice of democracy, human rights, and freedom. We broadcast across the darkness of dictatorship to keep the mandate of June 12 alive. They assassinated Alhaja Kudirat Abiola on June 4th in Lagos, thinking they could bury our voice. Her martyrdom will fuel the liberation of our people..."
Tactical Context: Launched in June 1996 by the National Democratic Coalition (NADECO) and exiled activists including Wole Soyinka, Radio Kudirat was named in honor of Kudirat Abiola, wife of detained elected president Moshood Abiola. General Sani Abacha's regime deployed heavy state jammer arrays in Lagos and Kaduna, but operators routed taped dispatches through clandestine offshore transmitters in Norway and South Africa, bouncing 7.185 MHz signals off the ionosphere directly into millions of Nigerian battery radios.
