    Tras muchos quebraderos de cabeza, y mucho tiempo invertido en probar soluciones infructuosas para poder trabajar en FT8 desde mi estación móvil, dada la imposibilidad de configurar debidamente la entrada/salida de audio por un problema de RF, decidí probar este Choke, con el siguiente resultado:

    INCREÍBLE: Ha sido poner este Choke (1 minuto de instalación) y se han abierto para mi las puertas del FT8, las cuales antes tenía totalmente cerradas ?. La RF ha desaparecido por completo: se ajunta mucho mejor la ROE, no interfiere en mi ordenador portátil, puedo ajustar los niveles de audio, etc.
    En unos minutos de prueba he conseguido trabajar varias estaciones Usa, varias de Argentina, Venezuela, Israel, Turquía, y prácticamente toda Europa.

    Muchas gracias, !Buen trabajo!

    Lo instale hace tres días, yo no había utilizado nunca un Choke de RF y la verdad es que estoy muy sorprendido de los buenos resultados conseguidos. Un saludo cordial de EA1GOZ Julian.
