Portions of southern North America remain stormy, particularly in coastal regions.  European storms are more widespread than the previous sessions impacting Western and Mediterranean regions primarily.  Isolated storms continue to impact central Japan and lightning is more widespread across Australia and New Zealand as storms expand in the region.

Geomagnetic conditions were quiet. The Bz is pointing to the North this morning and solar wind velocities are averaging near 305 km/s. DST values were very good and remain at positive levels.  Solarham reported a minor halo eruption CME at 0210z that may impact Earth’s magnetic field by February 15.

 

 

 

Propagation was quite good during the evening and overnight.  QSB remains active but domestic paths were open to somewhere and trans-Atlantic openings yielded a few elusive QSO’s overnight.  Reports suggest that the path from West to East was better than  the reciprocal early in the session.  Transcontinental openings were brief but reported late.  Trans-Pacific openings were average for the session.   Long haul over-land reports were present in Europe into Asia and across the equator into the Indian ocean.

Reverse beacon network reports follow:

The following stations provided reports of their two-way QSO’s and/or any additional activity that might have occurred during this session (this is not necessarily a complete list – only what was reported!):

Eric, NO3M, completed a JT9 QSO with PA0A at 0544z.  Eric indicated that Albert peaked at -17 dB S/N.  Eric indicated early in the session that he was being reported by G3KEV and OR7T at 0427z.  He was hearing quite a few European stations using WSPR:

Paul, N1BUG, completed a JT9 QSO with PA0A and posted the following details on the 600 meter research group reflector:

“We had decided to try JT9 attempts early in the window but also just before European sunrise, starting at 0530z. Conditions were not good early but during the night WSPR signals came up to very good levels.

NO3M and myself were calling CQ. I saw PA0A call CQ a little higher up and moved up to work him. Albert sent me a report but then lost my signal and completed with NO3M. Albert’s signal peaked -20 during that time. A little later I had him at -13 on WSPR. A few minutes later I found him calling CQ on JT9 again. We were able to complete a QSO but his signal was never better than -22.

I saw a weak signal on my CQ frequency a few times but could not decode it. Could this have been OR7T calling me? Rik had reported that he heard me several times.

Even with better conditions and good peak signal levels, QSB was a major problem… still quite deep with short peaks. I do not see how QRSS at any speed could have survived this.

Note: I had some problems with my internet service during the night. I’ve just seen that not all of my WSPR spots were uploaded…

 

Steve, VE7SL, reported JT9 QSO’s with KL7L and W0YSE overnight.  Steve was also reported in the East during the 0500z hour.

Ted, KC3OL, completed a JT9 QSO with WB4JWM.

Neil, W0YSE, reported at 0500z the completion of his WSQ session.  Neil was heard in Kansas and completed a QSO with KR7O.  He submitted these comments and statistics:

“I had announced on the chat that I was going to CQ on WSQ after 0400z. Before I could even CQ, I saw KR70 on my WSQ screen. We had a bit of a chat before conditions deteriorated. Here is the best part of what I decoded of our QSO:

I believe Robert is still operating at 4w TPO. If so, that was a good test of this mode. He is 614 miles south of me in Madera CA.

Also, in the middle of our QSO, I got a note on chat from Ted KC3OL that he had decoded some of my WSQ. Ted is in Lawrence KS, 1461 miles from my Vancouver WA QTH. That is my best reach so far in this mode. 

I am thinking I need to be available an hour sooner to get more action to my east, so will try to start at 0300z when I can.”

This morning, Neil reported a number of additional successes from the late evening and overnight:

After my WSQ activities last evening I had a JT9 Q with Steve VE7SL.

When I got up this morning, I discovered that WSPR had crashed about an hour after I went to bed. So I was heard by only 35, but managed to nab some DX by that time anyway:

That was the first time in awhile that Eden ZF1EJ decoded me.

 …and I was able to decode these 5: K5DNL, K9FD, KR6LA, KR7O, VE7BDQ before my program crashed.

Robert, KR7O, reported Good TC propagation and reasonably quiet conditions.  On JT9 I copied NO3M, K9KFR, N1BUG and KL7L.  Had a brief chat with W0YSE on WSQCall.  On WSPR I was copied by 31, including several TC stations that I have never reached before, including KB0PPQ, W0JW, W0DJK, KI3SW/5, N9LYE, SWL/K9, KU4XR, N1DAY, NO3M and DX stations  ZF1EJ, KL7L and K9FD.  Surprisingly, I only copied 12 stations, including WD8DAS, W3LPL, KL7L and K9FD.  Good to see Merv back on again.

KL7L 64 spots, -7

K9FD 86 spots, -4

Robert also successfully transmitted and received QRSS3 during the evening as he sorted out the software and SDR, captures presented later in this report.

Al, K2BLA, has built a U3S that he tested during this session with great results.  Its a rather unique setup designed to keep his main stations and home safer from lightning by using fiber optic isolation.  Al submitted this description of his setup.  He operated at 2 mW ERP during the evening and this morning and had very good results, as evidenced by these statistics:

Mal, G3KEV, reported that “last night I was in RX mode and early morning N1BUG was –19 at best and NO3M –15 at best, suitable for FT8 QSO mode.  My best DX on WSPR was FR5DH.”

Ken, K5DNL, operated WSPR during this session, reported 26 stations including PA0A,  G0MRF,  K9FD, KL7L and  ZF1EJ.  He received reports from 96 unique stations including PA0LSB,  G0LUJ,  F6GEX, F1AFJ,  PA0RDT,  G0VQH,  PA7EY, G8HUH,  F59706,  GM4OAS, K9FD/KH6, KL7L and  YV7MAE.  Ken reported nice receive conditions using his transmit vertical.

This was a fun night at KB5NJD.  I started making a few calls on CW, receiving a few reports from the reverse beacon network from WZ7I.  Ike, KW7T, also reported me with QSB at RST 579 in Colorado.  I was listening back West for Robert KR7O who was operating QRSS3 on 476 kHz.  The hope was for us to test QSO capabilities.  The complication was that we were working split so this was more of a fact-finding activity for future consideration.  We had good success as I was seeing Robert in spite of high QSB.  We will attempt a QSO in the future once I get a few problems worked out and get sensitivity and contrast properly balanced in Argo.  I think there might be a real possibility for QRSS CW in order to work a few of the more difficult  stations.  What’s old is new again…

Laurence, KL7L, operated JT9 during the evening, receiving reports from W0YSE and KR7O (but probably also others that were unreported!).  Laurence reported seven WSPR stations and he received reports from 24 unique stations including JA1PKG. He shared two-way reports with K5DNL, K9FD, KR6LA, KR7O, VE7BDQ, W0YSE and W7IUV.  Laurence added that “Sort of a mixed night with very strong sigs out to PNW but lukewarm elsewhere – JA closed…except for two 12/13z decodes from JA1PKG.”

KL7L session WSPR summary

 

Roger, VK4YB, indicated that “Local thunderstorms moving out to sea later. Very narrow spotlight centred on the PNW indicates a return of the Mackerel Sky, which has been absent for some time. No decode at KL7L but -8 at VE6XH. No decode South or East of K1YQP.  Only VE6XH decode my JT9 CQs. Merv made it once through the QRN for a 2 way WSPR exchange. Similar weather forecast for the rest of the week.”  Roger reported K9FD using WSPR and received WSPR reports from fifteen unique stations including 7L1RLL4, JA1PKG, JA5AEA, JE1JDL, K1YQP, K9FD, KPH, SWLCN74XP, TNUKJPM, VE6XH and VE7BDQ.
