Understood on the Morning Asia Pipeline to the NW US (and probably much of the Western states & Western Canada.True, 2 to 5 decades in the past it was truly wonderful. However 31 and 41 and 49 meters are still well populated starting pre dawn on the west coast, at around 1130 UTC and going on until almost 1730 (0330 to 0930 PST) those bands are lit up with many Asian, Indonesian, Japanese and other oceanic stations. China is ubiquitous in their presence and influence on shortwave with many differing programs and broadcast services. It's interesting because as China has come to DOMINATE the shortwave spectrum, they also at the same time are absolutely FLOODING the market with very cheap shortwave portables for the third world citizens without internet access. An XHDATA D219 just went on sale at ALI for under 7 bucks US. So yeah, the bands aren't as populated as was once the case, but they are very alive in the night time third world and eastern hemisphere.
Only about 80 minutes to go for KDWN, a station of legends.
But the 31 Meter Band generally is el deado at night. Partly due to propagation, partly due to there being less stations on the air.
When prop finally gets dependable for 31, 41, and 49 meters at night there hopefully will be more to hear. Until then, it's tune in Asia during the morning, especially when the ionosphere is cooperative...
