Where my results differ from what I expect, is approximately above 100Hz. Using an baseband of 1200Hz, I no longer get a signal sweeping from -ive to +ive, I get [a constant frequency of 1200Hz on the waterfall](http://imgur.com/BqGsRtK ), and aliased multiples.I believe that my sample frequency of 48000 is sufficient as my mf is 2400, and baseband is 1200.BW is (2 * (1200 + 2400)) = 7200HzNyquist is 2*BW = 14400HzSo, what am I doing wrong? Thanks in advance!
