RE: The Desert Whooper: FWIW, I did hear them several nights back, around midnight or later Pacific Time. I don't remember the night exactly, and my logbook is not handy....
They were just barely above the noise level, but I could hear the whoops.
Whether that was conditions improving on that evening, or something happened that improved the transmission, I wouldn't know. It was the first time I'd heard the DW in almost a year.
