That's an interesting observation and there is an easy way to check it out. If you feed the stereo Line Out signal from your K3 into your sound card while using Spectrogram (a free program) to observe both channels, you should be able to get a direct comparison of the two receivers. Spectrogram will even let you take a jpeg snapshot of the spectrum display. Any chance you might be willing to do that? If you don't want to mess with it, just record some of the audio as a stereo file and I'll run it through Spectrogram for you.
Just be sure to have all the same K3 settings (gain, bandwidth, shift, etc) for both receivers and tune both receivers to similar portions of the band. 73, Dave AB7E Richard Ferch wrote: > HB9ANM wrote: > >> what puzzles me is why this topic now suddenly pops up more >> two years after the first K3s appeared in the ham community?
