Thanks for running the test again Alex! First off, is this really IMD we're looking at? Aren't you injecting a single signal? Isn't this harmonic distortion, not IMD? Looking at the s9 agc off pre on plot, the worst "distortion" product is still >60dB down. It would be nice if we saw zero distortion products, but I suspect that the distortion seen here is completely inaudible. 73, Barry N1EU -- View this message in context: http://n2.nabble.com/in-band-IMD-test-tp1491448p1493610.html Sent from the [K3] mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
