Interesting Teotwaki? Same at this location.
Over the few years I've monitored "A", I always thought it might be groundwave to me, but after this winter "A" defiantly has a sky-wave component to it, fading out after 0300Z.
Although "A" can just barely seen on the Kiwi, even with the QSB, its gone from sight and sound after 0400Z. Keeping that in mind "A" is very good copy at TOKEN's Kiwi site (579) as well as Utah, Las Vegas and Winnemucca Kiwi sites (579 respectively).
