Trans-Atlantic activity opens wider and a power outage leaves the Oceanic reports in the dark

With a pun-filled Oscar Wilde-esque title like that, I should be writing for the newspapers!

Conditions over night were very strong but QRN from storms in eastern New Mexico and western Texas made copy complicated at times.  It seems those storms diminished over night and receive conditions improved locally.

I am dispensing with the 24-hour WSPR map today because conditions were so good that there were a large number of phantom spots caused by mixing of signals with noise.  To show the map would misrepresent what the band was like.  It was very busy, however, with station numbers rivalling and sometimes exceeding those seen on 20- and 80-meter WSPR.

In the east, WG2XJM, reported G8HUH and PA0A.  Eric indicates that he was listening to Europe with the 630-meter 8-circle array.

Also in the east, W1TAG/1 and WD2XSH/17 report PA0A.  Additionally WD2XSH/17 reports DF6NM.

In the Caribbean, Eden, ZF1EJ, reported the usual suspects including WG2XKA in VT.

Laurence, KL7L / WE2XPQ, did well in spite of an unsettled magnetic field.

In the Pacific, Merv, WH2XCR, experienced a power outage during the prime time opening to VK.  As a result, there were no results to report for VK activity.  The path to the mainland US was as strong as ever in the period proceeding the outage.  Sometimes it happens.  Its like the one that got away.

Conditions to the Midwest were very strong. Ken, SWLK9EN61, in Indiana sent the following screen shot that shows signals from my station at very easy CW and even phone levels for a considerable period of time:

WG2XIQ S/N was strong enough for a phone QSO in Indiana

Finally, over the past few years a signal has manifested itself between  475.630 kHz and 475.640 kHz.  In fact, it appears to look like two close-spaced signals.  The signal is observed world wide and is particularly strong when the band is open, and often best seen here in the early morning hours.  Last night the band appeared to open very early and Eric, WG2XJM, commented about how strong the signal was.  He determined that the signal appeared to be originating out of the west or north west.  I found that I too was seeing the signal on the waterfall very early and was able to null the signal to the west / north west.  When at its strongest, the signal sounds like a slight increase in the noise floor but no modulation is detected and the signal appears to be present continuously.  Ken, SWLK9EN61, sent the following screen shot:

Do you know what this is?  If so, please send me a message on the Contact page and let me know.  We have all been wondering for a few years.
