Current Operating Frequency and Mode

CQ 474.5 kHz CW

Big opening between WE2XPQ in Alaska and OH1TSM in Finland; Very confusing propagation as unsettled/storm levels continue to permit many strong trans-Atlantic and trans-Pacific openings; 2nd annual Midwinter 630-meter activity night tomorrow night (Saturday!); VO1NA CW reported at G3XKR and PA0RDT

The summary for February 3, 2016 can be viewed here.

Noise may have been slightly elevated in North America during the evening but it did not seem to have a major impact on reports.  In fact, amazing trans-Atlantic openings continue for many in the eastern US and Caribbean.   In the Pacific, QRN levels remain high but a few cases where the noise decreased have been noted, allowing signals to be reported.  The most remarkable opening of the session may be a polar path report between WE2XPQ and OH1TSM.  All of these great openings seem oddly timed based on the current state of the geomagnetic field.

12-hour North American lightning summary

 

Geomagnetic activity continues to show periods of unsettled conditions.  The Bz is currently pointing to the South and solar wind velocities remain in the high category, averaging near 640 km/s.  DST values have varied significantly  but in all cases remain at negative levels.

 

 

Lets begin with what is arguably the most remarkable report of the session – the polar path opening between WE2XPQ and OH1TSM.  This opening occurred just prior to sunrise at Laurence’s QTH although it was technically during this session due to time of day.  Teijo sent Laurence the following comments via email:

“I had just great pleasure to receive your WSPR -station 475.7 kHz at 1640 UTC.  I am using 2 x Perseus SDR and 12 pieces farm of about 1000 meters longwire antennas to various directions. For your signal I used 1000 meter longwire directed to the north, 358 degrees.  We listen here in Lappland on whole week in our DX-pedition at Lemmenjoki dx-site.  You can find info about our place from here: http://www.tapiokalmi.net/~kn1460/dx/lem/”

Laurence submitted the following reply comments which not only describe his station but also the local conditions in Alaska:

“Thank you very much for the report – looks like a pre dawn in Alaska opening over what was a pretty disturbed path – delighted as you are my first Lappland station, and delighted to have been decoded from the Lemmenjoki dx-site. The station was running around 200W output to an inverted L about 70ft vertical height and some 300ft horizontal, some sections are 3 parallel top cap wires. The driver is the QRP labs U3, driving a Class D PA designed by W1VD. It can be a difficult path and there are mountains close by in your direction that can knock out low wave angle but there is a small gap for 10 miles between two mountains so perhaps we were lucky or the wave angle was quite high. In any case thanks for the report…”

Steve, G3XKR, reported that Joe, VO1NA, had a nice CW signals on 477.7 kHz with QRSS10 in spite of increasing noise levels.  Roelof, PA0RDT, also reported Joe and indicates very little fading through the course of the night.

Report trails for these stations can be viewed here.

John, WA3ETD / WG2XKA, submitted the following comments about this session and his trans-Atlantic reports:

“Although conditions have weakened compared to earlier in the week, last night featured a new path to the lower southwest not often seen here.  Reporting were deep southwest stations W1CK, NO1D, and W0OGH, all new calls here.  WH2XCR checked in both ways, and PA0RDT, G0LUJ and PA0O spotted from northern Europe.  This session also featured a large quantity bogus ‘mixing’ spots, mostly all due south of XKA.”

Doug, K4LY / WH2XZO, experienced another good session and submitted the following thoughts and statistics:

“Continued very good conditions and activity with 20 unique decodes, including EA5DOM, and 51 decodes of WH2XZO.  Two way with WH2XCR like last several days, and 48 decodes of him the past two weeks compared to his good ears and 127 decodes of XZO.

Also two way with Neil, WG2XSV, who decoded XZO once last night after 16 previous decodes in January. We decoded Neil five times last night compared to two first ever decodes in January.

I know from his web sites that Neil has improved his antenna and think EA5DOM must have also because I was not decoding him a year ago. WH2XCR and also VE7SL sure are doing something right with their excellent hearing which puts XZO to shame!”

 Neil, W0YSE/7 / WG2XSV, reported that “XSV heard by 30 wspr stations. These are the ones over 2000 km”:

“Tried JT9 off and on until bedtime. Was heard by Toby/VE7CNF.  Joe/wb9sbd and Dick/w7wkr both listened for JT9 signals last night. Dick decoded John/ve7bdq at least once.  Thanks guys for listening for JT9.  I will beacon JT9 for Saturday’s event starting around sunset and for several hours, if weather permits.”

Neil also submitted a note to the 600-meter research group email reflector about his operating plans for the Midwinter 630-meter activity night on Saturday:

“In order to promote the use of JT9 on 630m, WG2XSV will be running  JT9 during the special event on Saturday [February 4th Pacific time] from about sunset (05 zulu) for several hours, then probably transition to WSPR for the remainder of the night until Sunday morning.

On 630m JT9 we use the same “dial” frequency as for WSPR, which is 474.200 kHz (USB) with an audio frequency near 1000 Hertz (+/- 200 hz) on the waterfall. If you decode my JT9 please email me at w0yse <at> msn <dot> com .

Thanx for watching for any and all activity by a lot of stations on Saturday night.”

 

Larry, W0OGH, submitted a report of the session via email:

“It was an amazingly good night for copy.  A couple of Canadian stations, a couple from Vermont, one from the Carolina’s, one from Florida, one from Arkansas, one from Oklahoma along with you out of Texas and one from BL11 out in Hawaii who was in here till 1402 gmt.  What a pleasant surprise.  At one time the WSPR screen looked busier than 20M!”

John, VE7BDQ, reported that he received ten WSPR stations and was reported by 31 unique stations after just five hours of transmitting (three transmissions each hour.)  John also operated some JT9 during the evening, with reports from VE7CNF, WG2XSV and W7WKR.  John noted that he would be transmitting until approximately 1600z.

Rick, W7RNB / WI2XJQ, reported “Well, not so cold this morning but we have had a little snow, not that it affected anything but just interesting, since yesterday was so nice with the sun out, etc. Conditions seemed to be about the same for the is session and the spotlight was not focused on anyone part of the country. Again it looks like there were less folks on WSPR this session.” Rick provided reports for nine WSPR stations and received reports from 36 unique stations.  His unique report details can be viewed here.

Paul, N1BUG, indicates that this session was poor from Maine but he did manage reports for EA5DOM.

The trans-Pacific path showed a bit more activity.  Report details, excluding KL7 and KH6, can be viewed here.

Roger, VK4YB, reported that “Improved TP propagation, QRN still high but enough gaps to pull through some DX. VK-JA path returns strongly, all on the NE beam.”  Roger received reports from JA1PKG, JA3TVF, JH3XCU, TNUKJPM, VE6XH, and W1CK.  He provided reports from WG2XXM and WH2XXP.

Phil, VK3ELV, experienced his strongest night in some time with reports from 7L1RLL4, JA1NQI, JA3TVF,  JH3XCU, and TNUKJPM.

Ken, K5DNL / WG2XXM, reported that he decoded nineteen WSPR stations and was decoded by 66 unique stations including VK4YB.  He added that WH2XCR reported him as a session best of +4 dB S/N.

Ward, K7PO / WH2XXP, received reports from 75 unique stations including JA3TVF, VK4YB, and VK2XGJ.

Mike, WA3TTS, reported that he was “Surprised with the overnight results as propagation did not seem all that enhanced early on in the evening…”  He submitted the following detailed statistics and comments:

“A good path to the south to ZF1EJ.  I used my NE antenna up to about 0300 then went to the NW direction. 3 dB points on the EWE cardio patterns about 120 degrees”

I did not get much operating time in the evening, instead relying on WSPR to evaluate the band conditions.  I was very surprised, like many others, at just how good the band was in spite of the current geomagnetic scenario.  My receive numbers returned to above 1000 reports and my transmission reports exceeded 2500 – just an amazing night of domestic activity.  My WSPR transmission report details can be viewed here and my WSPR reception report details can be viewed here.

WG2XIQ 24-hour WSPR activity

 

There were a lot of stations active during this session but I only took a single census at 0200z when 132 MF WSPR stations were observed on the WSPRnet activity page.  It was another very busy night on the band.

Laurence, KL7L / WE2XPQ, experienced an amazing session with the previously reported decode at OH1TSM.  The data was not uploaded to the database but a screen capture posted above provides proof.    It was a remarkable report from an unlikely path, even on a quiet day.  Laurence shared two-way reports with VK4YB and WH2XCR and received reports from JA1NQI, JE1JDL and TUNKJPM.  He also operated a second receiver, designated as KL7L.   DX report details for JA, KH6, VK, and OH can be viewed here.
