Hi all, Simon - I've reviewed your code a bit. You're not (yet) shifting the magnitude values over as needed before trying to extract the channel power out of it all. Specifically: * each bin has a 7 bit value; * the bin value is scaled by max_exp; * there's a max magnitude value which I don't think you need for spectral FFT reports; only radar FFT reports (since in radar FFT reports, the reported FFT bins are between 0..7/8ths of the maximum magnitude value) You're not scaling the data by max_exp in your FFT dump program, so the values aren't entirely correct. Are you doing it in the kernel code? I've just finished my first pass at this and plotting whatever values I get from the spectral data frames. I'll post more updates as I find/fix more bugs.
