Hola Estoy trabajando en mejorar la calidad del audio transmitido  a travez de amateur radios & en la cancelacion de interferencias causadas por leds principalmente.

Este año estamos en la parte mas baja de la avtividad solar lo que dificulta la propagacion de las ondas radiales y hay dias en que no se puede  uno comunicar.

Los filtros pasivos ayudan algo, pero ahora con la posibilidad de digitalizar el audio remover las partes de interferencia y volver a analogica la señal.

Es un proyecto que  produce satisfacciones porque se logran resultados.

Hace unos meses encontre un dispositivo que su creador hizo hace mucho tiempo.

Puso 2 antenas, una para referencia y otra para transmision. aparte hizo un transformador donde las señales de las dos antenas estan en contrafase. Unos potenciometros y un amplificador atenuador para cada circuito.

Lo fantastico es que con practica uno logra anular una señal invirtiendo las fases.

Es increible lo que hacemos cuando debemos resolver un problema.

Saludos a todos
