Current Operating Frequency and Mode

Probably QRT tonight and in the morning due to storms in the area

Weird, slow start to domestic session with signals originating from atypical directions but was a very solid night after band settled down; WA1OJN first JT9 QSO with K9MRI; Good CW signals from K9KFR; Good trans-Atlantic and trans-Pacific including first time AE5X -> ZL2AFP using WSPR; N1BUG takes maiden voyage using WSPR as he continues to improve his system; K3MF QRV first time and making station improvements

It was a quiet night in North America in spite of a few storms off of the Atlantic coast in the Southeast.  The Mediterranean and southern Europe continues to experience strong storms while much of Northern Europe was quiet.  Japan is once again experiencing lightning-rich storms at the northern end of the island.  Eastern Australia is currently struggling with more strong storms resulting in almost no reports by those stations.

11-hour worldwide lightning summary


Geomagnetic conditions were very quiet although G1 and G2 storm conditions are possible in the next few sessions according to Solarham. The Bz is pointing to the North and solar wind velocities are averaging near 340 km/s. DST values have been very stable and at or near positive levels.




Propagation was very good and improved significantly as the evening progressed.  QSB remained an issue but the effects moderated as propagation improved later in the evening.  QRN was exceptionally low.  An activity boost should come for this session and next as the 160-meter contest comes to an end.  Changing geomagnetic conditions may figure into that activity.

Reverse beacon network reports for the session follow:


We were joined for the first time during the evening by Wayde, K3MF, located in Pennsylvania.  He started the session reporting my CW CQ’s , noting that I was RST 539 while listening with a 500+ foot beverage while his hardware was still on the bench.  He went on to report JT9 from VE3CIQ, KB5NJD, K9SLQ, WA3ETD, WB4JWM and ZF1EJ.  That’s the list I have but there could be more.  Wayde is working toward getting a transmit antenna on the air and has quite a bit of space to work with so I have high hopes for his future on 630 meters.

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

Ken, W8RUT, completed JT9 QSO’s with K9KFR, WB4JWM, K2BLA, AA1A, KC3OL and VE3CIQ.

Bob, WA1OJN, completed what I believe is his first reported JT9 QSO with K9MRI.  Joe indicated that Bob was -19 dB S/N during the QSO.

Matt, KA1R, completed a JT9 QSO with W3XY.  Matt also indicated that “…It’s possible, but unlikely, that I completed a JT9 QSO with K9SLQ.  (I sent him -15 five times, he sent me -26 twice, and I sent him RRR four times, but did not see anything at all after the second -26.)

John, WA3ETD, reported a JT9 QSO with VE3CIQ and attempted a QSO with K9MRI but John indicates that QSB scuttled the final reports.  John also noted that NC8W and WA1OJN were QRV and new stations for this session.

Bob, K9KFR, sounded better than I have ever heard him on CW last night, completing a QSO with my station (KB5NJD) and followed up by a QSO that ended with QSB with W3LPL.

Tom, WB4JWM, completed JT9 QSO’s with K9SLQ and K0KE.

Keith, K0KE, completed JT9 QSO’s with WB4JWM and ZF1EJ.

Ted, KC3OL, completed JT9 QSO’s with W8RUT and K5DNL.

Steve, K5DOG, completed a JT9 QSO with K9MRI and reported JT9 from K0KE at +1 dB S/N.  He also heard W0YSE which is a pretty good haul from central Texas.

Ken, K5DNL, completed JT9 QSO’s with W3XY, ZF1EJ and KC3OL.  Using WSPR overnight he decoded a record 27 stations and noted that activity is increasing steadily.  He received reports from 88 unique stations including nine Canadian stations.  Ken shared two-way WSPR reports with VE3CIQ, K9FD (/KH6) and ZF1EJ.

Joe, K9MRI, completed JT9 QSO’s with K5DOG and WA1OJN.  He attempted a QSO with WA3ETD but QSB intervened.  He also reported CW from my station, indicating that my signal was stronger than he has heard in the past.  He made a few calls after resolving a frequency discrepancy (my suspicion) and he was light but audible briefly before fading due to QSB.

Al, K2BLA, reported “…vy low noise this AM but no JT9 activity. did wrk new one, W8RUT, last nite on JT9. WSPR: hrd by 62 and HRD 25. 2 way K9FD.

Neil, W0YSE, reported that he completed a JT9 QSO “…with K0KE in CO last night (S,R) -18, -23.”   Neil offered the following comments for the remainder of the session:

I also heard AH6EZ/W7 on CW just barely on 472.5 kHz. I tried to call him, but later discovered that, in my haste, I had not also switched the VFO-B over to that freq. Operating my xcvr in SPLIT mode is awkward at times, but it is what I am stuck with for now.

As for WSPR, out of 38 spotters, Eden, ZF1EJ decoded me 3x with a best of -25. I got as far east as WA3TTS in W. PA and was also heard in AK by KL7L. Here are those over 3000 km distant…

Now that the 160m contest is over we might see more activity tonight.”

Roger, VK4YB, reported that he is experiencing computer problems again and working to resolve those issues.  He added that “Unable to use 2-way modes owing to massive QRN. All my WSPR transmissions are heard in NA but always by the same 4 or 5 stations. A “Mackerel Sky” may be responsible.

John, W1TAG, reported a good night on 630 meter WSPR.  He offered the following comments and statistics for his activity:

“Heard by:
F5WK (1x)
LA2XPA (3x)
LA3EQ (1x)
G0VQH (1x)
G0LUJ (1x)

F5WK (8x)
PA0A (1)

Reception times were spread through the night. 0300 – 0330 seems to have been good. Hoping for another good night tonight. Expected solar coronal hole flow might kill the northerly paths by Tuesday. The last one was a weak event that just took the edge off of 630m propagation.

John, AE5X, indicated surprise at receiving WSPR reports from ZL2AFP.  He was one of two mainland stations during the session to be reported in New Zealand and wonders about the propagation mode.  Given his location with respect to salt water and the length of the path, I always place those openings in some type of ducting category.  I suspect noise in Australia limited his ability to receive reports from those stations.  John offered this write up on his blog.

Mike, WA3TTS, reported  that he “Heard 31 overnight. NE EWE early then NW EWE 0646 to past SR. Interesting I picked up my last F5WK decode a few minutes after switching to NW antenna direction and decoding K9FD…

Nice daytime decodes of W0YSE yesterday.  You can see the SR/SS transitions in signal strength in the log.  Neil was off air for some of the gaps in this sequence.

…There appears to be a daylight skip zone between ground wave and E (or whatever layer this is).  I regularly copy N6GN (319km) throughout the daylight at 0dB +-1dB.  I almost never copy NU6O or KR6LA during the day.  Not sure if they are transmitting.  N1VF has copied my 20mW ERP or so signal mid-day with decent strength also.  I have noticed the lack of these stations when there is extended daytime propagation.”

Terry, W8ARE, returned to air for the first time since the band opened under part-97 rules after repairing his antenna followed damage from a fallen tree.  Recall that Terry lives in a condo but made an arrangement to place a 40-meter vertical in the woods behind his house, out of view.  The antenna is now relocated to his patio but he expects that the HOA will ultimately give him trouble.  He is masquerading the antenna as a bird perch and bird feeder for now.  He had a strong session, reported F5WK and receiving reports from many others:

Paul, N1BUG, took his maiden transmitting voyage during this session and experienced good results at low EIPR.  He indicates that his antenna is a 90-foot tall Marconi-T with three, 100-foot long top loading wires, spaced five foot apart.  Total power out using the U3S is 200 mW for an anticipated EIRP of 15 mW.  Paul notes that his resistive loses are a bit high at the moment but he is working on that and he is currently using a variometer from a 1920’s receiver which he indicated in a previous discussion would have to change before any power increase is possible.

This was a good session at KB5NJD.  I started the session listening and found that the band was slow to develop with deep, but slower QSB than previous sessions.  Signals were also arriving from weird elevation angles, resulting in a profound lack of directivity from my receive antennas at times.    During the mid evening, I could not null K4EJQ’s CW calls around 473.75 kHz.  I found that the best receive antenna for the session was the multi-turn resonant loop and completed a CW QSO with K9KFR at levels that might be a record for him at RST  569 by the end of the QSO (his official report was RST 539 at the start.)  I heard Bob working W3LPL but Frank was just at the noise and subject to deep fades.  I noticed the same from K4EJQ through the session, which is atypical.  KR7O indicated that I was RST 519 during a few evening calls.  AH6EZ/W7 was at detection levels but never peaked enough for a call.  The same could be said for K3MF earlier in the evening.  Wayde called me with ten watts to his beverage and remarkably I could detect his signal but it was far too low for a QSO.  This report coincided with peak reports at WZ7I’s reverse beacon node in Pennsylvania.  I suppose those reports are the big news for my evening activity as they have been lean over the previous few sessions.  The band got better as the evening progressed.  I slept in this morning, missing any enhancements that might have been present.  With coming storm conditions, perhaps those will coincide with darkness and we might observe an onset enhancement.

Merv, K9FD (/KH6), reported a strange session:

“Strange conditions last nite,  came on about 0400 Z and not a signal on the screen, saw terribly weak trace on JT9,  no decode of course,  and nothing on WSPR.   Thought something wrong,  seemed like the band was noisy,  but not QRN, just a solid noise level. Was surprised this morning at the activity over nite.  but was dead again early this AM..”

Using WPSR, Merv reported seventeen stations including WE2XPQ at just milliwatts to a 50-foot tall vertical. He shared two-way reports with VK4YB and ZF1EJ. Merv received reports from 51 unique stations including 7L1RLL4, JA1PKG, JE1JDL, KL7L, VK2XGJ and ZL2AFP.
