      DttSP, the Linux sdr-core, will support as many simultaneous receivers
      as your CPU can handle. John g0orx/n6lyt is doing a lot of SoftRock
      work in that arena. Bob G3UKB had a prototype console running multiple
      receivers about a year ago.

        Tom,

        with Winrad it is straightforward. You just launch two (or more) instances of the program and tune in each instance
        the segment desired, in the mode desired, specifying in all instances the same input card and the same output card.
        If you are concerned with CPU utilization, just throttle back a little the upper waterfall speed, which is the main CPU
        consumer. The actual signal processing needs very little CPU. You can then switch among the various instances of Winrad
        with the Alt-Tab key combination. This only for the visualization. The audio output from each instance is mixed with
        that of the others, regardless of which one is on the screen.
