QRG Q code received using Compositor Software Max for Live devices

After creation of SASER SAS24P3L VLF radio station, I received a number of signals. Today at 15:35 GMT+3 Moscow time at the 29.5 kHz frequency using the 13 modulator I received a signal and then sent it back to MDL12 Max for Live VLF modem. After I stopped the transport in Ableton Live 9, I received a feedback loop with Q code: QRG.

The recording reads a Morse code for RG, Q letter is not present in a repeating loop. The received feedback signal according to 1912 International Radiotelegraph Convention Regulations means: “What line do you belong to?”

About my equipment: SASER SAS24P3L software uses modulation frequency to center frequency relationship called multiplier, which is responsible for signals receiving frequency in VLF band starting from 17 kHz to 44.1 kHz. This instrument takes in account Doppler Effect, which happens because of delay time changes inside waveguide. Related to this, frequency of the signal is changed. 320 channels available using 16 types of 4096-node continuous-phase frequency-shift keying modulation without external antenna need. Partial components of the signal may be muted or signal components may be muted fully using wave shaping distortion modules.


SASER SAS24P3L software synthesizer uses granular synthesis, splitting FM signal on the components, which have three parameters: phase, frequency and amplitude. Such approach in granular synthesis of FM carried out using continuous playback of these components back and forth. Positive and negative components of FM signal can coincide when the transmitter frequency dial is at 22,05 kHz. You should avoid this frequency to make the task of transmitter frequency detection harder. The derived function values work for all three levels of SASER SAS24P3L software. These levels are signal generation in real-time, granular synthesis and discretization. Received signal must comply periodical criteria for it to be synthesized with SASER SAS24P3L software.

SASER SAS24P3L v1.1 Max for Live

The model with modulation index of 11 has 12 component harmonics for positive part and 12 component harmonics for negative part. These harmonics sums up to 24 components, which has the derived values. The derived values of the 5th harmonic and higher, starting from the center frequency, fall into the same phase value simplifying the calculations. For SASER SAS24P3L software there is no meaning to work with modulation indexes higher than 11. The derived function has the hyperbola graphic also, but in a contrast with primitive function approximates curve values. The derived function suits for faster calculations and solves synchronization problems with discretization frequency of audio equipment of your device.


SASER SAS24P3L software is a hyperbolic system, working in the VLF band. The hyperbola graph can contract and expand in accordance with the transmitter frequency value.

Hyperbolic function

SASER SAS24P3L software serves for connection line detection. This problem is important when a signal transmitted on the large distances. If two stations, equipped with SASER SAS24P3L software, will be connected there will be no aliasing effect due to cascade of two 8th order Butterworth filters, which process the output signal in real-time and do not allow to spread the signal beyond the pass band of a channel, which equals ¾ of modulation frequency. Radio wave of this connection line will propagate on the large distances. The connection line has one receiving frequency of the signal, which modulated using the signal constellation. 4096-CPFSK modulator, applied to the frequency of receiver, serves as a phase spinning of radio reception in physical space. The parameters of spinning counted by Euler angles.

VLF propagation

SASER SAS24P3L software applied for mathematical approximation in physical space. The resulting, drawn on the 3D display of SASER SAS24P3L software has the structure of radio particles, passing through a pipe of waveguide and collapsible into the final image. These figures created in a presence of the signal constellations. These figures are not 2D, but a 3D images, which shows the topology of VLF network on this channel.

Ether decomposition using Morse code method

Ether received via MDL12 Max for Live modem is a property of its original sender. However, I developed a method of Ether decomposition using the AVOX Max for Live resynthesizer. The pass band of AVOX is capable of SLF translations suitable for submarine communications. Thus turning back to an original intent of merging both Sonar and Radar technics together and working on a signal level, MDL12 Max for Live and SASER Max for Live is a solution to induce such communication.

While it is an extremely tough task to decompose the Ether received with SASER Max for Live, I set up a server running special edition of SASER software. It is fully autonomous and registers signalizations in a special binary file. Later I use these signalizations to travel back and forth in time using SASER Max for Live as a feeder for MDL12 Max for Live modem.International Morse code

Here I present several recorded signalizations out of MDL12 Max for Live modem, which are manually decomposed using Morse code method.

In the first file I decompose Ether from bottom to top, lower pinging comes first and then middle rhythmic bar.

For example, File 1 has a code pinging inherited by me as:

Lows: ..- (U)

Mids: (S)

Giving me a consolidated marking as “US” at the end of file decomposition. A trained operator can decompose such Ether feedbacks in real-time by using MDL12 Max for Live modem relatively quick.

File 2 is for Russian marking and is somewhat more difficult as it uses beats instead of vertically placed Morse code ping bars. File 2 is an example of such Ether and consists of following codes:

Beat 1: .-. (R)

Beat 2: ..- (U)

This gives marking as “RU” at the end of decomposition.

I admit that the first file is not resynthesized original Ether and the second one is resynthesized clean version of original translation.

Another example of Russian marking also uses vertical bars as in US example, however the labeling starts from top to bottom:

Mids: .-. (R)

Lows: ..- (U)

It is you who decide if such Radar-Sonar system efficient or not, but taking in account that SASER is completely real-time system and acts on a signal level rather than radio frequencies the task of identification the potential threat is a subject of 5 ms to detect the threat and up to 30 sec to receive feedback from it to identify whether it is friend or not by using SASER as a feeder for MDL12 modem.
