I think I have a misunderstanding regarding tuning the USRP. I have connected the TX-A directly to RX-A. I am plotting the FFT of both the transmitted and received signal. I have tuned RX to 0 Hertz so I expect the positive frequencies to look the same up to noise affects.
What I get instead is mostly noise, with occasional blips at an offset frequency. I.E. 5 KHz input gives me occasional energy at about 3 KHz. But most often I don't see any signal at all. I have posted the GRC graph and FFT plots at http://wyoinnovation.blogspot.com/. Thanks in advance for any help you can offer.
