Last night was noisy here in Texas.  Blitzortung showed a few lightning strikes in Louisiana and Illinois but the reports were not consistent with what I was hearing.  It seems others were experiencing noise as well.  WSPR reports generally seemed down but there were numerous positive S/N reports that seemed oddly out of place compared to other reports during the same period.  WSPR activity at 0400z included 56 active MF stations, as reported by on the WSPRnet activity page.  Several stations were operating other modes, off air due to wet conditions, or in a receive-only capacity listening for other stations running other modes.

The geomagnetic field stabilized a bit  through the session, peaking at Kp = 3 but the Bz component was southerly, as reported by the Space Weather Prediction Center.  Solar wind remained above 500 km/s.

The  Kyoto DST remained at or near zero through the session.

In the Caribbean, Eden, ZF1EJ, has reports for active stations in the south:

Trans-Atlantic activity was once again limited to the path between DK7FC and WD2XSH/17:

In Alaska, Laurence, KL7L / WE2XPQ, appears to have been in receive-only mode, reporting only WH2XCR.

In the Pacific, Merv, K9FD/KH6 / WH2XCR, had another strong session with two different reporting stations in Japan:

WH2XCR 120115

WH2XCR 24-hour WSPR activity


WH2XCR JH3XCU1 120115

Paul, W0RW / WA2XRM, operated QRSS30 overnight with very good results and reports from a number of stations. A few screen shots are shown below:

wa2xrm QRSS60 SWLK9 120115

WA2XRM QRSS30 “RW” signal reported by Ken, SWL/K9, in Indiana


WA2XRM QRSS30 XIQ 120115

WA2XRM QRSS30 “RW” signal reported by John KB5NJD / WG2XIQ in Texas

Larry, W7IUV / WH2XGP, saw a partial call sign at 0221z but with heavy QSB.

Paul was audible here in spite of the broadcast spur adjacent to his signal.  Its Paul’s belief that the sinusoidal nature of his signal is the result of his furnace cycling off and on during the transmit period.  My station also lacks frequency stability over a QRSS30 time scale so the receiver drift does not help matters.

Neil, W0YSE/7 / WG2XSV, Toby, VE7CNF, and John, VE7BDQ, operated a few digital modes in the later evening as beacons, coordinating the mode and making reception reports in the ON4KST chat/logger.  The group started with MFSK8, with Toby reporting Neil from -5 to -18 db S/N.  Switching to frequency modulated Hellschreiber, Neil was reported by Toby and John.  Joseph, NU6O (pending WI2XBQ), also noted that he was both seeing and hearing the signals.  Neil sent this print of Toby’s signal:

Other anecdotes and statistics follow:

Mike, WA3TTS, reports that the northwest EWE is quieter than the southwest EWE and this may the reason that Merv, WH2XCR, is decoded so often while listening to the northwest.

Doug, K4LY / WH2XZO, indicated early reports from Rudy, N6LF / WD2XSH/20.  Doug also called CQ on 474.5 kHz CW before bedtime and received a reception report from Bill, N3CXV / WH2XRR, starting at RST 439 and building to RST 559 moments later.

This morning’s CW session at WG2XIQ was cancelled due to a number of computer problems that took precedence.
