Radio: it's not just a hobby, it's a way of life

Current Operating Frequency and Mode

OFF AIR; Storms expected overnight into Saturday morning. Planned start time for WG2XIQ in Field Day demo is 1800z on 474.5 kHz CW, WX permitting

Geomagnetic storming continues but overall terrestrial storm QRN was down for many and stations in the South fared better than those in the North; Great trans-Pacific openings between North America and Oceania; Strong night for WH2XCR on Molokai

This was the first relatively quiet night in many day here in Texas.  There were storms present in the southeastern US but it was my impression from listening that lightning was not a constant feature, however, Doug K4LY / WH2XZO, located in South Carolina reported more damage to his antenna top loading and above average noise level.  It just depends on where you are located.

Geomagnetic conditions continue to be active, with the Kp ranging between 5 and 6 through the session.  The Bz continues to point to the South this morning but less so than the previous session.  Solar wind velocities are averaging near 730 km/s this morning.  DST values are, as expected, quite negative and suggests severely disturbed band conditions.  Based on both indicators presented below, the southern hemisphere seems to have fared far worse than the North but this assumes that measurement methods are the same.  Trans-Pacific results suggest an enhancement was observed on paths to and from North America and Oceania.

 

 

 

I recently reported that I received a note from a European station asking why I did not include OPERA reports in my daily summaries to which I provided a response.  In the last few days there have been some very rational discussions that may help clarify the situation in the long term.  I am not an OPERA user so I am relying on the information that I have been provided.  It seems there are multiple flavors of OPERA available.  One version purportedly uses Internet correlation and something called “dynamic spots” which may cause angst with many operators while a second modified version does not utilize these functions.  There are apparently other variations but it seems the modified version also has a documented emission scheme for its on-off-keying although there is some question about whether that documentation is currently available in the public domain.  I have a PDF file that was sent to me but I don’t know which version it actually represents (I suspect this documentation is for the favorable version).  What I have expressed to the individuals that have been engaging in these rational discussions in an effort to clear up any misconceptions is that their mode has a serious public relations problem.  An Internet search reveals that the narrative has not changed for OPERA in several years and that in order to change public opinion an effort is needed to distance from the objectionable version in addition to addressing the issues that have been part of the original narrative.  That should probably be done on a website and should probably be very thorough, including clear evidence and detail that differentiates the versions.  How can I tell while looking at the data that the version in use is OK compared to another version?  Where is a link that allows me to download the documentation?  Those are just a few of the types of issues that will need to be addressed, I think, before there will be any opportunity for real changes in public opinion to be realized.  My position doesn’t change at this time.  I am staying out of the matter aside from politely accepting the details that have been provided to me on both sides of the argument.  None of this is a change for me as I have never reported OPERA data and the first time that I have actively referenced the mode was just days ago in response to the original question.  Once clarifications about OPERA are made for all to persistently see (posting the information on email reflectors does not count!) I may be able to rethink my position and perhaps begin including some details.

David, G0MRF, reported that EA4GHB was QRV on 476.24 kHz QRSS3 and was nearly at CW-levels at 2216z.

There were no trans-Atlantic CW or WSPR reports during this session.

Al, K2BLA / WI2XBV, reported good band conditions.  He decoded nine WSPR stations and was decoded by 21 unique stations.  Al indicates that he shared two-way reports with WH2XCR at a distance of 7567 km as well as WH2XGP and WD2XSH/20, both stations near or in excess of 4000km.

Phil, VE3CIQ, reported strange conditions in Ontario where he only decoded WG2XKA in Vermont.  He was decoded by eighteen unique stations.

John, WA3ETD / WG2XKA, reported light rain, high local QRN and 100-watt TPO for the session.  He decoded nine WSPR stations and was decoded by 23 unique stations.  The path to the Pacific Northwest was missing and most of his reports were East of the Mississippi River.

Neil, W0YSE/7 / WG2XSV, reported many JT9 reports for VE7BDQ at his station with the best report at -2 dB S/N.

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

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

Roger, VK4YB, enjoyed enhanced propagation and provided these comments for his evening operation:

“Tonight conditions were very good. I had 5 DX stations, WG2XXM, WH2XGP, WH2XXP, WH2XCR and WD2XSH/20, in the log soon after sunset. After just a few transmissions, S/N reports were in the mid teens in the Pacific North West. Even JA3TVF was decoding my signals as early as 11:00z. Neil, WG2XSV was in there too. Clearly something was afoot. Time to issue a code 7 alert and go for a 2xCW QSO with Steve, VE7SL. Only a faint trace of Steve’s CW made it to Brisbane and nothing at Steve’s end. We abandoned the attempt as the sun rose in VE7. I switched back to WSPR  and discovered WH2XCR was decoding my signals at +1 S/N. My all time high has been a +3 at his QTH, so this was indeed very good propagation. I mused that had Merv been at the station controls with the cans on, He would have heard my CW and Steve’s pounding in at Q5 and wondering why we couldn’t hear each other.”

Roger’s complete list of receive reports includes JA3TVF, VE7BDQ, W7IUV, WD2XSH/20, and WG2XSV.  He also shared two-way reports with WH2XCR.

John, VK2XGJ, reported early openings down to -20 dB S/N for WH2XXP:

Rudy, N6LF / WD2XSH/20, provided reports for ten WSPR station and he received reports from 34 unique stations.  He shared two-way reports with VK4YB.

Ken, K5DNL / WG2XXM, reported that he decoded nine WSPR stations and he was decoded by 49 unique stations including VK4YB.

Larry, W7IUV / WH2XGP, provided reports for eight WSPR stations and he was decoded by 35 unique stations including VK4YB.  As W7IUV, Larry provided reports for eight unique stations including VK4YB.

Ward, K7PO / WH2XXP, received reports from 47 unique stations including VK4YB and VK2XGJ.

With geomagnetic conditions as they are currently I opted to run only WSPR through the session.  Amazingly, reports were not that bad.  Plenty of stations, including higher latitude stations like WG2XKA and WH2XGP, were reports here and I didn’t seem to have significant problems moving my signal to the North.  My transmission report details can be viewed here and my reception report details can be viewed here.

Eden, ZF1EJ, provided reports for ten WSPR stations including WH2XCR and he was decoded by ten WSPR stations.

Laurence, KL7L / WE2XPQ, experienced an identical session to the previous session, sharing two-way reports with WH2XCR and providing reports for WD2XSH/20.  I am sure the aurora is amazing at Laurence’s QTH right now.

WE2XPQ 24-hour WSPR activity

 

Merv, K9FD/KH6 / WH2XCR, experienced what seems like a fantastic session, with DX reports from 7L1RLL4, JA3TVF, JH3XCU, VK2XGJ, and ZF1EJ.  Merv shared two-way reports with VK4YB and WE2XPQ and provided reports for VK5FQ.  In the eastern US, Merv shared two-way reports with WI2XBV and reports, two-way and otherwise, in the central and western US were nominal.  Merv’s DX report details can be viewed here.
