Geomagnetic field receives another jolt of unsettled conditions yet trans-Atlantic openings for New England flourish; Trans-Pacific openings favored lower latitudes; ‘Goodbye to Winter ‘ MF QSO Party coming this week for Europe; Post-sunrise reports between WH2XCR and WE2XPQ

The details for March 12, 2016 can be viewed here.

Most stations seem to report that QRN was low during this session but anytime a station is near or even under a storm, it can be a completely different situation and that was the case here at my station overnight.  Even so, propagation seemed to be on the rebound in spite of addition geomagnetic activity.  Trans-Atlantic openings were observed by a few stations, although less wide spread than in recent memory but at least Europeans are being reported here in North America for a change.  Trans-Pacific openings seemed to favor lower latitude stations during this session although big openings to Asia were present from KH6.

12-hour North America lightning summary

 

Geomagnetic activity reached unsettled levels again after more than 36 hours of quiet conditions.  The Bz continues to point slightly to the South and solar wind velocities have increased to nearly 390 km/s, up from the previous session.  DST values decreased during the peak of unsettled conditions but began to rebound this morning.

 

 

 

Vinny, DL6II, reports that as Winter comes to a close in the northern hemisphere, there will be one last MF QSO party this weekend:

 

Vinny also encourages the use of WSQ2 which can be downloaded here.

Trans-Atlantic openings were present, at least for stations in New England and most notable is the return of reports for European stations which have been missing for a few days, likely due to high noise and impacted propagation.  Report details can be viewed here.

David, G0MRF, reports that he activated the SWUKSDR remote receiver.  David reports many serviceable decodes, adding “…there were a couple of periods when the signal was between -17 and -21 when QRSS3 would have worked for a QSO. Of course that does not help in getting a signal back in the other direction!”

Al, K2BLA / WI2XBV, reported relatively low noise at sunset which increased significantly about one hour after dark.  That would correlate well with sunset in my area where noise was high and likely propagating into the darkness.  Al indicates that noise was down some this morning.  He provided reports for ten WSPR stations and was decoded by 32 unique stations including VE7SL who, with two-way reports shared with WH2XCR, represent his best DX for the session.

Paul, N1BUG, reported low noise with transcontinental and trans-Atlantic openings to WH2XGP, EA5DOM, and G8HUH, respectively.  He decoded thirteen WSPR stations.

Doug, K4LY / WH2XZO, reported, “As rain turned to wet snow last night, I was able to transmit a few hours and was decoded by 37.  Continuing moderate QRN  limited decodes to 11, including WH2XCR.  Maybe the cold fronts predicted for this coming week will reduce QRN?”  I hope Doug sees QRN improvement with his cold front.  My cynicism suggests, however, that noise is here stay until October.  I hope I am wrong.

Ernie, KC4SIT / WI2XQU, reported that QRN was really tough for him.  By late evening he indicated only five reports, down from thirteen in the previous session.  By morning Ernie had provided reports for twelve stations.   Part of this may be the fact that many of us were QRT for storms, DX and contests.

Rick, W7RNB / WI2XJQ, reported high winds in the Seattle area, forcing him to shut down early.  For the time he was on the air, he provided reports for seven WSPR stations and was decoded by twenty unique stations.  Rick’s unique report details can be viewed here.

Mike, WA3TTS, indicate that the Spring edition of the Stew Perry Topband DX challenge may have “…limited the PNW activity, best dx overnight was XCR and XGP, other PNW stations were no shows….”  He provided these statistics for the transcontinental openings that were present:

Trans-Pacific report details, excluding KL7 and KH6, can be viewed here.

Hideo, JH3XCU, posted links to two tables showing US -> JA DX totals and US -> JA peak S/N for the session.

Roger, VK4YB, has recently experienced a number of improvements in long haul reports but those seemed to have dried up in this session for some reason.  He received reports from VE6XH and W7IUV and provided reports for WH2XXP.  As has been previously reported, Roger has been engaging in some comparison between 630-meters and 160-meters with Dan, VE6XH.  Roger reports that there isn’t enough data to draw any conclusions yet but with this interim data there do not appear to be any correlations.  In fact, he indicates that “the worst day on 630m turned out to be the second best day on 160m.”  Roger had this to say and provided the dataset to date and graph:

“On 160m I am running 100 watts TPO to a sloping dipole with one end at 100ft high. It slopes exactly towards VE6XH. On 630m I am running 220 watts TPO to my North East beam, which is a 900ft long wire incorporating a 120ft vertical section at the max current point.

On the receiving end, VE6XH is using the same medium sized loop and low noise preamp on both bands. His loop is broadside to VK.
Here’s a prediction from Mr Murphy. Next weekend is going to be super good on 630m.  That’s the weekend I will be running a 40m contest station for the local radio club and I will be QRT on 630m!”

 

Ward, K7PO / WH2XXP, received reports from 63 unique stations including JA1NQI, VK2XGJ, VK4YB, and ZL2AFP.

Larry, W7IUV / WH2XGP, provided reports for twelve WSPR stations and was decoded by 48 unique stations.  As W7IUV, Larry provided reports for seven WSPR stations including VK4YB.

Laurence, KL7L / WE2XPQ, had nice coverage of the western portions of North America.  The path to JA and VK was completely cutoff, however.  One of the highlights was what appears to have been late, post sunrise reports between Laurence and WH2XCR.  Sunrise in Alaska was around 1624z, but the last report came at 1648z.  Paul, N1BUG, indicates that this was just eight minutes after sunrise in KH6.  Still its pretty remarkable and these late openings seem to be more common this time of year.  Laurence’s other two-way report details with WH2XCR are included in Merv’s report details.

Merv, K9FD/KH6 / WH2XCR, experiences another consistent session with reports from 7L1RLL4, JA1NQI, JA3TVF, and JH3XCU as well as two-way reports with VK4YB, ZF1EJ and WE2XPQ.  See WE2XPQ’s entry above for information and report details on  a late report of WE2XPQ that occurred after sunrise at both ends of the path.  Merv also noted in an email that he had early evening storms that were quite close to his QTH.  At sunset during one of these storms, he received strong signals from ZF1EJ.   Its clear that Merv was hearing very well during this session, with reports for WD2XSH/17 in the Atlantic coast of Massachusetts as well as WG2XPJ in Vermont.  Reception of Merv’s signal was also good in the Midwest by a number of stations and Merv also shared two-way reports with WI2XBV this morning.   DX report details can be viewed here.
