As reported by ARRL, a few days ago, on July 7th the 25 MHz antenna for WWV was changed to circular polarization. http://www.arrl.org/news/wwv-25-mhz-signal-swapped-to-circular-polarization
Matt Deutch, N0RGT the Lead electrical engineer at WWV said it’s hoped that the latest antenna change to circular polarization might be helpful to anyone studying radio propagation (ionosphere) during next month’s total solar eclipse (August 21, 2017), which will be visible across the US. “My effort right now is focused on getting the word out, just to make people are aware that [the 25-MHz signal] is available, if it can be useful to them.” greg, w9gb Sent from iPad Air _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
