From a recording.
The carrier appeared at 0404, about 15 db above the background noise. There were excursions to about 20 dB over. I heard no audio until 0437 when there was some instrumental music (an oboe?). The carrier was gone at 0439.
The Elad suggested that the frequency was 6924.95.
In my corner of suburbia, with my ears, 15 dB over the noise in AM doesn't work. I need at least 25, but prefer 30.
