    Shortwave Radiogram, Program 349

    Hello friends,

    If you were close enough to its path, I hope you had a view of the April 8th eclipse. Even if clouds obscured the sun, the brief presence of darkness during the day is quite a phenomenon.

    I found the filter glasses that we had from the 2017 eclipse, so my wife and I took turns looking at the 88% coverage here in Arlington, Virginia. That, and the shadows on the ground, were unusual and amazing.

    I monitored WWV or 5 and 10 MHz during the afternoon. My thinking was the signal from Colorado would hit the ionosphere in the vicinity of totality on its way to Virginia. On an SDR, the 5 MHz signal went from nothing to faintly visible on the spectrum display, and back to nothing. The 10 MHz signal went, by my ear, from weak to fair and back to less audible, but I need to do some more precise measurements from the recording.

    Three photos of the eclipse will be among the eleven images (all MFSK64) in this week's Shortwave Radiogram.

    A video of last week's Shortwave Radiogram (program 348) is provided by Scott in Ontario (Wednesday 1330 UTC). The audio archive is maintained by Mark in the UK. Analysis is provided by Roger in Germany.
