Well, I heard 'em on the way to my Cactus League ballgame late this morning, and then tried to listen this afternoon after the game.... POOF! They weren't there! Must have some bugs to work out yet.
I WILL say, listening with a non-critical ear, they seemed to be the same signal strength as before... I'll listen closer the next time I hear them...whenever that might be... (Sincere wishes for good luck to the engineer folk!)
