There are $20 USB dongles, but > they lack the frequency range and bandwidth I'm talking about. The dongles typically do 60MHz-1700MHz--I doubt that you'll do better by hooking an ADC to the BBB. The dongles do it by having a front-end tuner and specialized signal processor. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
