I'm also not convinced that this particular screen shot is non- linear distortion. It could be aliasing in the FFT software that's part of the decoder. On the other hand, the pdf below DOES show both harmonic distortion and IM distortion on the Line Output when the Line Out level is set too high (driving the transformer being driven beyond it's ratings). http://audiosystemsgroup.com/K3FilterStudy.pdf 73, Jim Brown K9YC _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
