Comparing tuners.

Hi All, The rtlsdr dongles come with different tuner chips. Have a look at this video: http://www.youtube.com/watch?v=cVU5X1d2XYU Four dongles are run simultaneously with the same input signal. A seven port resistive combiner is used to combine a noise source, a signal generator and a sweep generator and to distribute the combined signal to the four dongles. The screen shows three instances of SDRsharp running the three tuners plur one instance of Linrad with the E4000 tuner for which Linrad allows a different gain distribution that provides a much better suppression of false signals. The Linrad screen is pixel-oriented so the video should be looked at with high quality. Regards Leif / SM5BSZ
