Weak Signal Propagation Reporter (WSPR) spots on 20m during the 2024-04-08 eclipse

I ran my Flex 6400 at low power (5 W) to generate propagation data for the HamSCI project during the 2024-04-08 total eclipse. The WSJT-X program generated the signals. With the SmartSDR iOS and MacOS apps and Google Remote Desktop, I was able to monitor the station and control it remotely.

The radio telescope did not get built in time. Nor did I participate in the Solar Eclipse QSO Party.

It’s fun to see just how far a decent antenna–my end-fed half-wave (EFHW)–got out with only 5 W. And I’ll look forward to the report about how the eclipse affected the ionosphere.

As the website itself claims,!
