Hi all
I am new to HF underground but an active HF listener.
I came across this strange broadcast on 4755khz and wondered if anyone had any thoughts what it might be. New to me but might be familiar to others.

Yes catmandoes, this is a numbers station called S06 (ENIGMA designation) and "The Russian Man". Specifically this is what is called a "null" message, meaning no actual encoded groups were sent, and so there was no message.
For future reference, it is best if you include not only the frequency, but also the time and date (both in UTC) to help identify a signal. Sometimes the date and time can narrow down options with a less identifiable signal.
At a guess, if you recorded this today, it was at 2000 UTC. This station has a regular schedule the 1st and 3rd Saturday of each month (in March) at 2000 UTC, on 4756 kHz.
T!
