Live off-air recording of the clandestine station Radio Biafra on 19 December 2015 beginning at 20:50:31 UTC on a shortwave frequency of 11600 kHz. This was one of the first broadcasts after Radio Biafra's return to the air following the termination or non-renewal of their contract with the previous transmitter facility. The program begins with the Biafran national anthem at 20:50:36 UTC, followed by a piece of music and then extended commentary in English. The program abruptly ended at 21:43:36 UTC. Believed to be scheduled between 20:00 and 23:00 UTC, the delayed start of the program, some audio dropout during the program, and the abrupt end of the program, may indicate studio to transmitter link problems. The speaker announced that it was a live transmission. 

The broadcast is believed to be from the Kostinbrod (near Sofia), Bulgaria, transmitter site with a transmitter power of 100 kW and is directed to Southeastern Nigeria.

The broadcast was received by the Web-interface wideband software-defined radio at the University of Twente in Enschede, The Netherlands, with a "Mini-Whip" antenna in AM mode with 5.09 kHz RF filtering. Reception was fair with some fading.
