While reading about the February 26 Incident I learnt that Kita Ikki knew of it and provided some support to the coup by phone. A documentary about Asian 20th century history contains a small portion of one of these calls made by the rebels to Kita to inform him of their coup attempt, however it's barely intelligible. Where can I find this recording and possibly those of other calls made? Are there transcripts of any of them?
For reference, the documentary is by PBS and it's called "The Pacific Century". The call I'm referring to can be found in this video starting at 42:18
