Morse code transmission over the Voice of Turkey's signal

I have been regularly recording the small spectrum window containing the endangered stations I mentioned in one of my previous posts. Three days ago I noticed something strange: a morse code transmission superimposed onto the Voice of Turkey's signal on 9460 kHz (video below):

Using SDR# I extracted the coded signal while suppressing the rest of the audio (recording embedded in the player below):

My Morse knowledge is patchy to say the least, so I decoded it using Fldigi. At the start of the recording, the sequence "8T1" is repeated a dozen of times. I Googled around and found another YouTube video of a Morse code transmission from a numbers station, reportedly codenamed M01, which also had multiple repetitions of "8T1".

Numbers stations are still sending messages from many different corners of the world. However, if I indeed captured an M01 transmission in this instance, what makes it unusual is that it was embedded inside a signal from a broadcast station and that it was strong enough to be heard clearly. I'll watch out for further occurrences of M01 on the airwaves.

Update: I received the following pointer from @priyom_org:

@LondonShortwave Not M01, but rather M14. Sends daily 1900 UTC on 9463 kHz and repeats 1930 UTC around 7353 kHz.

While the station supposedly operates daily, it's the first time I heard it over the Voice of Turkey's broadcast at that time of day.
