Ordinary and extraordinary? I.e. different polarisations being refracted at different heights.
I am surprised it is that much delay though. If it was the other way around then Ground wave vs Sky wave would be a reasonable explanation but this is ruled out if the vertical was receiving the crashes later and in any case the extra delay would be very short. Alternative explanations: One antenna was favoring the short path and the other the long path. The vertical radiation pattern could cause this. The Vertical would ideally have a low radiation angle and may then favour long path, so local storms might travel around the world to reach the vertical but also arrive at a high angle on the horizontal via a shorter hop. You were hearing different crashes or an echo that was vertically polarised. There is a known DSP delay on the K3 that depends on the filter bandwidth, but that would only be a few 10s of ms at the most. So if you have the 150Hz filter set the audio may be 10ms behind that of a wide open filter. You have programmed the K3 to have a longer delay than I thought plausible (AFX?). I don't think the K3 delay is more than a few ms. You have a longer delay from one ear than the other or a problem in your wetware. I hope it is not this. It would imply you have become unbalanced, but you might expect this would happen all the time even on a single receiver, so it is not likely.
