It was noisy in the southern US as a storm system progresses to the East.  Europe was mostly storm-free except for activity through the Mediterranean.  Australia is becoming more active in the southeastern population centers and points to the North.

11-hour worldside lightning summary

 

Geomagnetic conditions remain at quiet to elevated-quiet levels. The Bz is pointing to the North this morning and solar wind velocities are averaging near 350 km/s.  DST values are variable but trending towards negative levels this morning.

 

 

 

Domestic propagation was decent early but very fast and deep QSB continued through the night.  Transcontinental openings never developed very well and shorter hops went flat by mid-evening.  Early trans-Atlantic paths looked promising but were a bust and reports suggest that those openings were one-way, with signals primarily moving from Europe to North America.  This seemed to change as the session progressed with more equality in paths.  Spotlight propagation was also suggested during the early part of the session.  Trans-Pacific propagation was reported as average at best.

Reverse beacon network reports follow:

 

Joe, VO1NA, reported that he was QRV on 477.7 kHz CW during this session.  PA0RDT reported that the trans-Atlantic path to Joe was down but provided the following capture:

Bill, VE1YY, reported that North American JT9 stations were strong and submitted the following JT9 receptions early in the evening:

Rolf, LA2XPA, submitted these JT9 stations that were heard at his remote outpost in northern Norway:

Mal, G3KEV, reported during the trans-Atlantic test that “Condx very variable tonight, rapid QSB on signals around EU, up and down by several dB.  Things could change but I am not hopeful…no decodes of any NA stn although I am getting reports from VE1YY and NO3M at present, looks like one way propagation…I was getting decodes from VE1YY, VE9GJ, NO3M propagation seemed to be one way E > W. but strangely N1BUG did not see me.  I did not decode any NA stns.”  The test turned out to be a bust as everyone’s luck finally ran out.

Rik, ON7YD, reported that “Not a single TA copy so far, neither way.  Even Mal is getting no further than Nova Scotia.  Propagation is going downhill I’m afraid.  I will stop transmitting but leave the RX on JT9 all night.  Tomorrow I will see what I missed.”

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!):

Scott, N2BJW, completed his first reported JT9 QSO’s during this session with NO3M, K9KFR, N1BUG and WA3ETD.  He reported to WA3ETD that he is using a ground dipole with about 250 watts applied.

Wayde, K3MF, completed JT9 QSO’s with NC8W and N3FL.  Wayde also worked Sal, K1RGO, using CW.

Eric, NO3M, reported a CW round table with K1RGO and N3FL on 474 kHz during the early evening.  Later he called AB5S who was calling CQ but both stations faded on each other so no QSO was completed.  Early in the session Eric worked N2BJW using JT9 for a new grid and heard G3KEV’s JT9 transmissions:

2320 -26 1.8 1201 @ CQ G3KEV IO94

2354 -27 1.9 1158 @ CQ G3KEV IO94

Paul, N1BUG, completed a JT9 QSO with N2BJW for a new grid.  The trans-Atlantic test didn’t go so well and he reported during the early evening that “It’s not looking promising here. I will continue for a while but I am afraid propagation is going down hill. We missed the really good stuff a few days before we started this JT9 activity !”  This morning Paul indicated that “Propagation was not kind at my location last night. I was heard fairly well by LA2XPA but I did not decode any European stations on JT9.  WSPR confirmed poor conditions. As one example, the best signal I saw from G0MRF was -19. On better nights he is often in the -15 to
-12 range.

John, WA3ETD, completed JT9 QSO’s with N2BJW, N1BUG, WB4JWM, NC8W, KA1AL and VE3CIQ.  John called me on JT9 but the window closed rapidly and never really opened very well again.  John indicated that he checked the band again at 0230 AM ET but the band was completely flat.

Tom, WB4JWM, completed JT9 QSO’s with K5DNL, K3MF, N3FL, KA9OKH, VE3CIQ, K2BLA, KC3OL and WA3ETD.  Using FT8, Tom worked K9KFR.

Phil, VE3CIQ, made a valiant JT9 QSO attempt with KA1AL as the band was crashing.  Both stations stayed with it for a very long time but  Phil never received a confirmation that KA1AL received his report.

Al, K2BLA, reported that he “Worked WB4JWM and NC8W last night amidst a lot of noise. WSPR: Heard by 62 and heard 15. Nothing exciting; some west coast and no TA.”

Ken, K5DNL, operated WSPR during this session, reporting 24 stations and receiving reports from 94 unique stations including LA2XPA, F59706, G8HUH, G0LUJ, EI8JK, GM4OAS, ZF1EJ,  ZF1RC, KL7L,  YV7MAE and eight Canadian stations.

Neil, W0YSE, indicated a rough, meager night using WSQ.  He reported that:

“I beaconed my WSQ all night again. Dont know if anyone received it other than John VE7BDQ with whom I had a short QSO using WSQ. I think Roger ve7vv was in there also but I did not decode him, altho I believe that John did.

I am thinking that I will not beacon with WSQ tonight, unless someone requests it. I am also open to trying other Non-Linear modes for QSO’s or experimentation. Otherwise I will get back on JT9 and WSPR for now.”

Clemens, DL4RAJ, reported WSPR stations from North America later in the evening following a poor path earlier in the evening:

Clemens noted that “K4SV is quite rare here and W3LPL even more.”

Stefan, DK7FC, reported that “Yes the condx were down a bit but i still got some good reports from remarkable distances. So the path E > W was not so bad.

The -6 dB at AA1A is good for arm chair copy in CW, normal speed…”

Activity at KB5NJD was short-lived.  I started out with JT9 but when the TA test flopped I transitioned back to CW for a bit.  I worked K8TV for the first time in several months.  Ken’s signal was very nice prior to calling him but once he responded it was obvious that the band was on its way down and he completely disappeared.  I never heard him again during the session.  I returned to JT9 for a few minutes, working K3MF and attempted another QSO with WA3ETD but the band was crashing and a QSO was not going to happen during this session.  My brief calls with CW resulted in no reverse beacon reports so the band was a bit erratic and not at all in a good way.  I’ll be back tonight, weather permitting.

KL7L session WSPR summary

 

Roger, VK4YB, reported that “QRN was moderate but got worse later. This hampered tests with the new W5EST Top Fed Delta Loop. I have a temporary low voltage tuning capacitor in the loop, which I will replace with a wide spaced one, when I discover the correct value. In the meantime I can only run low power on it.  The noise floor is about the same on the TFDL as my NE beam. It receives VK signals better than the beam but W7IUV was much weaker on the TFDL. This is as expected. On low power Tx, VK3ALZ was receiving the TFDL at about the same strength as the Bottom Hat with the same power into both.  I am not sure that the TFDL is tuned correctly. The capacitor peaks the neon tube nicely at about 400pF. The inductor in the other leg is an arbitrary value and I have not tried changing it.  I don’t know if the current in the inductor peaks at the same time. Very early days yet, but encouraging.  Propagation was only average. My JT9 was decoded by KL7L, VE7SL and VE6XH as reported by PSK. WSPR reports extended as far as K5DNL.”  Roger reported two WSPR stations and he received reports from 23 unique stations including 7L1RLL4, JA1PKG, JA3TVF, JA5AEA, JE1JDL, K5DNL, KL7L, KPH, KR6LA, KR7O, N1VF, TNUKJPM, VE6XH, VE7BDQ, VE7CNF, W1CK, W6SFH and WB7ABP.  He shared two-way DX reports with W7IUV.
