The Voice of Turkey recorded shortly after the "official," though contested, April 16 2017 referendum. The following recording starts around 2315 UTC and begins with the end of the English language service (at marker 14:00). The German language service follows. This recording was made on 9830 kHz with a WinRadio Excalibur and sky loop antenna in North Carolina, USA.
Here is an additional recording of the referendum results broadcast by Richard Langley. This Voice of Turkey broadcast recording begins a minute or so before 22:00 UTC on a frequency of 9830 kHz. The signal originates from a 500 kW transmitter in Emirler, near Ankara, Turkey, and was beamed 310° to Europe and North America. By the way, the announced broadcast schedule at the beginning of the broadcast was incorrect while that at the end of the broadcast was correct.
The broadcast was received indoors on an Eton Grundig Field BT receiver with its built-in whip antenna in Hanwell (just outside Fredericton), New Brunswick, Canada, in AM mode with narrow-band RF filtering. Reception was generally good with some radio-teletype interference at the start of the broadcast.
