Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

Very poor session with ‘selective’ propagation as northeastern stations attempt another night of trans-Atlantic JT9 tests; East -> West trans-Atlantic paths dominated the early part of the session; QSB was brutal once again; Trans-Pacific paths were impacted by noise and antenna damage at VK4YB; KL7L -> JA path opens this morning

Strong storms were present again along the gulf coast making listening a challenge in the South.  The Caribbean experienced a few isolated storms and a few Pacific storms persist East of the Hawaiian islands.  A few storms were present in northern Europe while the most active storms remain in the central Mediterranean.  Central Japan experienced a few isolated storms and Australia is largely unchanged from the previous session with an active system on the eastern coast that is creeping northward.  The west coast remains very active and storms in the Sea of Tasman may threaten New Zealand shortly.

11-hour worldwide lightning summary

 

Geomagnetic conditions were quiet. The Bz is pointing to the South this morning and solar wind velocities are averaging near 311 km/s.  DST values remain variable and the presented measurements were once again at odds with the other.  Proton concentrations were elevated during the evening, peaking at 70 p/cc for a number of reporting periods.

 

 

 

The band was extremely poor and “selective” during this session compared to recent sessions.  QSB was a major factor again, perhaps worse than we have observed in a very long time.  Openings were present but they were often short-lived and not very robust.  20 dB differences in signal level were not unheard of in the span of just a few minutes.  Trans-Atlantic paths improved overnight allowing reports into the central US.  Trans-Pacific paths were also decent but noise and antenna damage impacted one station in Oceania.  The path between Alaska and Japan opened again.

Reverse beacon network reports follow:

Mal, G3KEV, reported that he “…was decoded last nite by AA1A, W1VD, W1IR N3FL, N1BUG, VE3CIQ.  Condx not too  bad during the early hours.   N3FL received me at -9dB suitable for a CW QSO”   NO3M was also reporting Mal through a number of periods during the evening.

Rik, ON7YD, reported that “…TA propagation often has a final peak just before EU sunrise (6-7 UTC), about midnight at the East Coast. That might be another window to watch.”

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, reported a very nice CW QSO with WB3AVN on 474 kHz.  Eric indicated that Frank was using 40-watts TPO to a 100 foot inverted L.  Eric also reported G3KEV during the evening but the path was not reciprocal.

Tom, WB4JWM, reported JT9 QSO’s with K3MF, K9KFR and KC3OL.  Using FT8, he worked VE3CIQ, K9KFR and KC3OL.

Paul, N1BUG completed a JT9 QSO with N3FL in the early evening. He also reported that this session’s trans-Atlantic tests using JT9 were a bust.  He posted the following on the RSGB reflector:

“Last night was again not good here. I received G3KEV just once, with -25 signal at 2352z. Mal was working a SP5 station at the time. Looking at WSPR data, it appears conditions improved later in the night.

I want to thank everyone in Europe and also North America for being part of these tests over the past week. I hope some will continue but I will not QRV the coming night. I will be listening for EU on LF without making self QRM from MF transmissions.

I do want to try some more when it looks as if conditions have again improved. Many more QSOs are possible.

Paul also noted that “…It seems sometimes when I have poor propagation it is going further south and west. I did notice I had DK7FC at -14 last night (late), which is a few dB stronger than in previous nights.”

Ted, KC3OL, completed a JT9 QSO with WB4JWM and a JT9 or FT8 QSO with VE3CIQ.  The mode details were note clear.

Wayde, K3MF, completed an FT8 QSO with VE3CIQ.

Al, K2BLA, reported a very poor session, indicating “Horrific lightning noise from storms in the Gulf. Worked WA3ETD last night and that was it for JT9. Also low activity. On WSPR: heard 16 and heard by 43. Nothing notable.”

Ken, K5DNL, reported a JT9 QSO with WA3ETD.  Using WSPR overnight, Ken reported 23 stations including G0MRF and KL7L.  He received reports from 96 unique stations including EA8ARZ, PA0RDT, G0LUJ, PA7EY, KL7L, G0VQH, EA8BFK, F59706, G0KTN, YV7MAE, F1AFJ, G0MRF, ZF1EJ and seven Canadian stations.

Neil, W0YSE, took advantage of what openings were present using WSQ.  He explains:

“I had an hour long session on WSQ last night with John VE7BDQ. He was successful at pinging my machine for SNR reports at both .5 and 1 baud speeds. We both experience some QRN near the end of our QSO and John’s signal went way down as the QRN hit. The noise was wide and buzzing. Wondering if the earth was hit by solar wind… 

I had a carrier at our original dial QRG of 476.5 so I was sending messages prior to our sked to QSY down 100 hz. So we will stay on Dial 476.4 for a Sunday night session at 8pm PST.

Neil also reported JT9 from KL7L at -26 dB S/N at 0623z.

Laurence, KL7L, operated a bit of JT9 during the overnight period, receiving a report from W0YSE:

0623 -26  0.3 1101 @  CQ KL7L BP51

Using WSPR overnight, Laurence reported seven stations including VK4YB and he received reports from 27 unique stations including JA1PKG, JA3TVF, JA5AEA and TNUKJPM.  He shared two-way reports with K5DNL, KR6LA, N1VF, VE7BDQ, W0YSE and W7IUV.  Laurence was using the normal, full-power station through this session.

Roger, VK4YB, indicated that “Storm went through here late this afternoon. Only caught the edge of it but very strong winds. Several antennas are down. Mains Power failed and only now restored.  Bottom Hat 2 is still in operation and I got a couple of spots from KPH and VE6XH before their sunrise. Path to JA is good.  Luckily I slackened the tension on the TFDL, and I think that has survived. I will report full damage in daylight.”  Roger received WSPR DX reports from 7L1RLL4, JA1PKG, JA3TVF, JA5AEA, JA8SCD5, JE1JDL, KL7L, KPH, TNUKJPM and VE6XH.
