[Elecraft] This morning on 40 meters: some DX, and over-the-horizon radar

 Testing the K4.  It's a dirty job, but somebody's got to do it.

 Two things were booming in this morning on my K4D: very loud over over-the-horizon radar (Chinese? Russian?), and Thailand (E29TGW). I'm pleased to report that the new K4 noise blanking algorithm completely suppressed the former, and that I worked the latter. 

The radar signals presented as an undulating "dragon" on the panadapter, blanketing about the lower 20 kHz of 40 meters. The panadapter's own noise blanker slayed it, though, knocking it into the atmospheric noise.

Next time this pops up I'll do a video.
