    Sorry, but, I doubt that any userspace application developer will find those descriptions
    useful.

    For the threshold: I understand that this is the carrier strength used to detect a
    channel, right? If so, please improve the description.
    Also, The better is to associate its scale to a carrier level in some unit like dB.

    The second control means absolutely nothing... It is not a boolean value, and what
    is "alternative" frequency mode?

    Cheers,
    Mauro.
