Gr-scan - Scanner de frecuencias

ANTRAX · Octubre 28, 2019, 01:36:00 PM

Gr-Scan es un programa escrito en C++ y compilado sobre GNU radio, rtl-sdr, y el codigo de bloque OsmoSDR.Está previsto para escanear rangos de frecuencias e imprimir una lista de señales descubiertas.

Debería funcionar con cualquier dispositivo que funcione con el bloque, incluyendo dispositivos Realtek RTL2832U.

Este programa fue desarrollado utilizando un Compro U620F, que utilizan un sintonizador E4000. El producto parece no estar disponible en los sitios de US, aunque el nuevo receptor DVB-T (dispositivos Rtl2832U/E4000) tienen buenas revisiones.

Ejemplo de uso:

Iniciar a escanear en los 100Mhz (-x 100) y finalizar en los 105Mhz (-y 105), pausar por 5 segundos en cada canal (-p 5):

Código: bash

root@kali:~# gr-scan -x 100 -y 105 -p 5

Código: bash
