Problemas con el modulo lab_ofdm

Hola! 

Al abrir el archivo layer_a o layer_b  y ejecutar, gnu crea las GUI pero no duran mucho tiempo, no importa si en el bloque file source le ponemos repeat o no. Tenemos el throttle_rate en samp_rate/8192 (con throttle_rate=samp_rate/1.0 ni siquiera abre) y se mantiene unos segundos mostrando graficas que cambian muy lento antes de cerrarse automaticamente.

Alguna idea de qué podemos estar haciendo mal?

Saludos, Santiago

Hola,

Necesitaríamos más detalles para poder ayudarte. Por ejemplo: escribe algo en la terminal cuando cierra? qué versión de GNU Radio? es en el docker o instalado nativo?

saludos

No parece un error, pego la terminal abajo. Es GNU 3.8.1.0 corriendo en ubuntu 20 (una VM en VirtualBox)

Ademas, mirando el top no parece una falta de recursos

Hola,
Así, sin mayores pistas, la veo difícil de diagnosticar. Hablamos mañana en la consulta, pero probaste usar el docker?
