The WWV signals on 25000 and 20000 kHz have been routinely audible lately up here near Seattle. But just after midnight locally this morning, I heard WWV on all of its shortwave frequencies at the same time; been a long time since I remember that last happening. Good to excellent signals on 5000, 10000, 15000 and 20000 kHz. The two "end" frequencies -- 2500 and 25000 kHz -- were fair at best.
