Did you get my report on XRS startup last night? I sent three reports but never got one here so I gave up.

Dex started out OK and got stronger right up to sunset (the yellow marker, at 6:29 PM CDT).  Both experienced a little fading after that, somewhat more intense on /5, then recovered to a nice solid level.

At 1750 m, noise was similar to 2200, which was more of a challenge for a Part 15 signal, but SIW came through in barely recognizable bits and pieces.  It was already down in the 30s two hours after sunset, so I abandoned my post.
