Probably QRT tonight and in the morning due to storms in the area

Another night of ‘pretty good’ domestic openings; Less prolific trans-Pacific openings but path between VK and JA, KH6 continues to perform reliably

IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet.  Please continue to be patient and let the FCC finish their processes.

There were fewer storms in and around North America during this session but I noticed during the evening that storms in West Texas were making quite a bit of noise here in the DFW area.  Fortunately this activity dissipated overnight leaving primarily activity in the north central US that seemed to ramp up as sunrise approached.  Domestic openings were pretty good but trans-Pacific openings were fewer in number.  Trans-Atlantic openings continue to be completely cut-off.

Solarham is reporting that the forecast coronal hole is now geoeffective and solar wind velocities should begin to increased over the next 24-hours.  Thus far geomagnetic conditions continue at quiet to elevated-quiet levels although the Bz is pointing to the North and solar wind velocities are averaging near 395 km/s with several excursions into moderate territory above 400 km/s.  Proton numbers have been observed at high levels for short periods  but have generally been elevated over the entire session.  DST values are beginning to exhibit signs of degradation as levels are approaching or have moved below the center line.




Ken, K5DNL / WG2XXM, reported that he decoded five WSPR stations and he was decoded by 46 unique stations including WE2XPQ, WH2XCR, ZF1EJ and six  Canadian stations.

Doug, K4LY / WH2XZO, reported that his QRN was down a bit.  He provided reports for ten WSPR stations and he was decoded by 33 unique stations.

Rick, W7RNB / WI2XJQ, provided reports for six WSPR stations and he was reported by eighteen unique stations.  Rick’s unique report details can be viewed here.

Dave, N4DB, reported that he decoded ten WSPR stations with ZF1EJ representing his best session DX.  Dave noted that stations in the Pacific Northwest and British Columbia were not represented at his station overnight.

Mike, WA3TTS, indicates that the previous session was better but he reported  “12 stations decoded overnight, using SE, NE, SW EWE antenna directions in the evening and then NW after 0400 for overnight. Station results by distance and best SNRs…

Neil, W0YSE/7 / WG2XSV, reported that his WSPR program crashed during the night but he provided eight JT9 reception reports to VE7CNF, best at -8 dB S/N.

Al, WD4AHB, reported:

“I switched over to using an Inverted “L” antenna for last night’s Rx session. It runs NW-SE and is ~135’ in length.  I use it with a 73-material binocular core 9:1 un-un and for this session a 530 kHz 7-pole low-pass filter at the receiver end. I was curious about what differences I might get trying something other than the PA0RDT design mini-whip I normally use.

With this antenna configuration there was more noise to deal with but very at manageable levels. The two antennas seem to be very similar in their response.

I’m characterizing this period as “May Madness” and so I present my “Elite Eight” which have been pretty consistent spots over the last few days.”

Hideo, JH3XCU, provided a link detailing VK -> total JA DX  and VK -> JA peak S/N for the session.

Roger, VK4YB, reported, “Low to moderate QRN but not able to detect any long haul DX tonight. I could not even make it to NA on 160m. Thus a double blank with VE6XH.  Path to Hawaii is holding strong and Japan is still receiving.”  Roger received reports from 7L1RLL4, JA1NQI, and he shared  two-way reports with WH2XCR.

Larry, W7IUV / WH2XGP, provided reports for four WSPR stations and he received reports from 34 unique stations including ZL2AFP.  As W7IUV, Larry provided reports for six WSPR stations.

I once again started the session with CW about 20 minutes before sunset in North Texas.  Noise was elevated and noticeable as storms in West Texas moved eastward.  Those storms dissipated rapidly and noise was down by morning.  I expected to have a quick sked to check out another operators station but the timing did not work out so I called CQ for about 45 minutes or until I was about half-way to full darkness.  I transitioned to WSPR and, like the previous session, received almost immediate decodes from the Midwest and Southeast.  My transmission reports were very good with QSO-quality levels observed.  Those report details can be viewed here.  With previous counts normalized to my 17% duty cycle, my number of reports were at typical levels for this time of year.  The same can be said for my reception reports.  Reports were up significantly from the previous session and those report details can be viewed here.
