Chinese Numbers station, Morse code, ENIGMA ID M95, 9153 kHz, 31 March, 2024, 1310 UTC

This is the Chinese numbers station ENIGMA ID M95. M95 is not a traditional "spy numbers" station, it is probably military related but the purpose behind it has never been confirmed.
M95 is typically active on multiple frequencies, during its periods of activities. It has a loose schedule, with start times being inexact and only roughly defined. It does typically transmit several times a day. Most often it is found on at least 3 different frequencies when it is active. In this case it was transmitting on this frequency, 9153 kHz, and was also simulcast on 7553 kHz and 4243 kHz.
In this case the Morse code is on 9153 kHz (center freq, or zero beat), but as I am using the receivers USB mode to demodulate the Morse I have tuned the radio to 9152 kHz, in USB mode.
The M95 signal is associated with two other signals, a voicesister signal, known as V26, and a digital signal, Chinese 4+4 modem format, known as Q26. All three signals carry traffic with similar formats.
A description of the format can be found here: www.numbersoddi....

Disclaimer: Many of the radio reception recordings on this KZbin channel pertain to unusual, uncommon, unknown, or mystery signals that might be found on radio, both shortwave and VHF/UHF. Among the subjects covered are numbers stations, utility stations, military transmissions (both in the clear and encrypted / encoded), aviation, maritime, ham radio, CB radio, radars, ionosodes, propagation beacons, ditters, dashers, whistlers, and just about anything else that might transmit, in any mode, USB, LSB, CW, Morse Code, FM, AM, FMCW, LFMCW, etc. Think of it as SIGINT (signals intelligence) / COMINT (communications intelligence) / ELINT (electronic intelligence) lite, the hobby version. All the recordings are made by me, most often at my home. Although there are a few mysterious things to be found here, you will not find anything paranormal, extraterrestrial, spiritual, or mystic. However, everyone can have their own interpretations of the sounds heard, make of it what you will.

Those little sounds in the back, almost like a futuristic zap , could those be images being transmitted with the encrypted code ?

No, the periodic "tweep" sounds you hear are unrelated to the M95 Morse transmission. Those sounds are chirpsounders, or chirpsondes. The chirpsounder is a specific type of ionosonde. Ionosondes are used to measure the current propagation properties of the ionosphere.
