Hola a todos.

Hace mucho que no dedico tiempo a escuchar señales mas o menos raras. En este caso y no estoy seguro me parece una transmisión de la OTAN en modo ASTANAG o algo parecido.
Repito, no estoy seguro.
Saludos.

No conocía eso así que busqué y...

STANAG 5066

Escribió:

STANAG 5066 (Profile for High Frequency (HF) Radio Data Communication) is a NATO specification to enable applications to communicate efficiently over HF radio.

STANAG 5066 provides peer protocols that operate above an HF modem and below the application level. STANAG 5066 includes the mandatory SIS (Subnet Interface Sublayer, sometimes called Subnet Interface Service) protocol that enables an application to connect to an HF modem through a STANAG 5066 server over TCP/IP. This enables a clean separation between application and modem.

STANAG 4285

STANAG: Used by the military, comes in many different variations. Pretty much all Stanag traffic is encrypted. STANAG 4285 is the NATO standard for HF communication. It consists of several sub modes (75-2400 bps) and two different interleaving options (short and long). The receiver should be in USB mode and provide flat frequency response from 600 Hz to 3000 Hz. Another Stanag mode is 5066, which includes mode identification in it’s data and can therefore be detected correctly by multimode auto detectors that are built into some software.

Hola,

A todo esto, veo que usan un programa llamado SIGMIRA que descifra ese código de la OTAN...

Y por lo que veo en el vídeo, transmite texto bastante rápido, para ser HF;

Buenos días.
Supongo que habrá varios programas capaces de decodificar esas señales, yo utilizaba el SkySweeper.
Saludos.
