    It is not clear to me why you would want to change the channel. All
    information is transmitted on both channels. If you were to change
    the channel on a one channel unit you would be likely to miss it,
    whereas if you receive constanmtly on a single channel you will
    eventually get all of the data that is being transmitted in your vicinity.

    Because ship characteristics are only transmitted once every six
    minutes, a two channel receiver is desirable, to make sure you get
    that in time to do something about it.

    Best,

    Steve
