Radio: it's not just a hobby, it's a way of life

Typical Operating Schedule

Usually QRV CW most evenings, tuning between 472.5 kHz and 475 kHz with CQ's on or near 474.5 kHz. Occasionally QRV JT9, 474.2 kHz dial + 1000 - 1350 Hz. QRV some mornings starting around 1100z on CW. Sked requests are welcome. All activity is noise and WX permitting

Very quiet geomagnetic conditions result in a very rare and unlikely first time opening between K9FD (/KH6) and LA2XPA; Big night for JT9 and CW QSO’s as quiet terrestrial conditions continue for much of North America including transcontinental QSO’s between VE7VV and NO3M and also reports for W3LPL by stations in the Pacific Northwest

North America was reported to be very quiet in spite of a few storms surrounding the continent.  Southern Europe was covered with storms containing lightning while central Japan was the target of a few storms this morning.  Australia remains active with strong storms impacting population centers in the South.

11-hour worldwide lightning summary


Geomagnetic conditions were very quiet. The Bz is pointing slightly to the South this morning and solar wind velocities are averaging near 345 km/s, down from the previous session. DST values look great, with both presented indicators at positive levels.  Solarham reports that G1 storm levels are possible beginning on December 17.




Propagation was very good during the evening and overnight in spite of fast, deep QSB.  Noise conditions were extremely low in North America and activity was high.  A number of high latitude transcontinental openings were reported.  A transpolar opening was reported between the Pacific ocean and northern Europe.  It was a good session.

Reverse beacon network reports follows:


David, G0MRF, reported an upcoming remote operating activity starting on December 19 that may give North American stations a very good chance to work him using JT9.  David will be using an Icom 7300, amplifier and filtered preamp from a very quiet site that he has used in the past.  The antenna will be 114-foot tall and located at a high location if I am recalling correctly.  Mark your calendars as David is planning on losing sleep to make this event a success.  More details will be forthcoming as the date nears.  David notes that this event will go through the New Year or until the antenna falls down.

Jim, W5EST, submitted the following screen capture of his WSJTx console showing JT9 activity observed at his station in Little Rock, Arkansas (click to enlarge):










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!):

Neil, W0YSE, listened for my CW this morning and submitted the following report for that activity as well as his JT9 QSO list and overnight WSPR activity:

I just barely (but definitely) heard a couple of “cq”s this morning on 474.5, but no call sign. Then, later, when I was back to 474.2 USB I could see a thin line off and on at the 300 hz mark on the waterfall. It might have been you. The line would be about 20 or so seconds long and then a pause and then show up again. It did that for about 3 or more times as I recall.

My JT9 Q’s for last evening were: NC0B (CO), KA7OEI (UT), K5DNL (OK), VE7CNF (BC)

…and PSK reporter showed several west coast decoders of my JT9 from VE6 to So. California as well.

RBN showed this on my cw cq:

VE7AB   W0YSE 474.2     CW CQ  13 dB     16 wpm   0442z 16 Dec

This morning Ken, K5DNL, and I had a JT9 QSO. Ken struggled to get my report. but finally did. He was -19 at best. 

As for WSPR, I was decoded by 57 stations which might be my best so far, even as part 5 “XSV” perhaps. Here are those over 3000 km….quite a bunch:

(It sure would be nice to be heard by some of them on JT9 !!!)

And Eden came thru for me with a best ever of 13 decodes…. Wow.

…and I heard these 10 WSPR stations: AE5X, AH6EZ, K4SV, K5DNL, K9FD, KA7OEI, KL7L, KR6LA, W3LPL,  and W8RUT…

Al, K2BLA, reported that he “Worked 3 new stations on JT9 last night; W8CDX, KA7OEI and KK1W. Worked W8ARE and WB4JWM for fun.”  Using WSPR overnight, Al reported 24 stations including K9FD and he received reports from 47 unique stations.  Al also completed a CW QSO with me this morning, sending RST 559 as I reported him at RST 539 while listening Northeast so I suspect he was significantly stronger.

Eric, NO3M, completed JT9 QSO’s with VE7VV on a very long and often difficult transcontinental path.  He also completed a CW QSO with me.

Basil, W8CDX, completed JT9 QSO’s with K2BLA, KB5NJD, W8ARE, W4JWM, W7IUV, N1DAY and NC0B.

Tom, WB4JWM, reported JT9 QSO’s with W8RUT, K5DNL, W8CDX, K2BLA and KC3OL.

Frank, W3LPL, reported good propagation to the Pacific Northwest as was heard using JT9 by W7IUV and VE7SL.  Frank added that he shared two-way JT9 reports with CF7MM but based on his comment, he did not complete a QSO with Mark.  No ‘new’ initial QSO’s were completed but Frank noted that the path to the Pacific Northwest was also very good using WSPR overnight.

Terry, W8ARE, completed JT9 QSO’s with W8CDX (new), K2BLA, KK1W (new), W3XY and K5DNL.  Using WSPR overnight, Terry reported 29 stations and he was received by a personal best 55 stations using only a 19-foot-tall modestly-loaded vertical on the patio of his condo with approximately 40 watts TPO.  You can view a description of his bird-feeder antenna here.  No one should ever claim that they can’t get a station on the air!  Ever.

Roger, VE7VV, reported a JT9 QSO with KA7OEI and a very long transcontinental JT9 QSO with NO3M, which Roger indicates is his best DX over land.

Ken, K5DNL, reported JT9 QSO’s with VE7CNF,  WB4JWM, W0YSE, KC3OL and W8ARE.  Overnight using WSPR, Ken reported 21 stations and he received reports from 94 unique stations including KL7L, K9FD (/KH6) and eleven Canadian stations.  Ken shared two-way WSPR reports with ZF1EJ and VE3CIQ.

Ted, KC3OL, completed JT9 QSO’s with WB4JWM, W8RUT and K5DNL.

Larry, W7IUV, completed a JT9 QSO with me, KB5NJD, quite early in the evening and reported KA7OEI on CW shortly afterward.  He also completed JT9 QSO’s with NC0B, W8CDX, and NC8W located in Ohio, which was a new state for Larry.

Rob, NC0B, reported that it was an “Odd night with some very strong signals, but sometimes no decode in the middle of a QSO with KA7OEI with a solid waterfall each time and with over +5 dB both ways.  W7IUV was +3 to +5 all night.  W8CDX was a new contact for me.”  Rob reported that he also completed JT9 QSO’s with W0YSE, NC8W and K9KFR.

Roger, VK4YB, reported that “TP is locked into the same pattern as yesterday. If ZL was active, there would be a parallel path to S. calif.  Looks like there might have been a similar pattern over the Atlantic with ZF getting in to LA but no where else in EU.  I suspect that the pattern, I call the Mackerel Sky, only forms over the oceans. There is no evidence of it over land. It is strong.”  Roger added that over the holidays he hopes to experiment with the “Special Top Fed Delta Loop Antenna” as described by W5EST in this description.  Roger submitted the following picture of the capacitor he plans to use for the project – its almost as big as he is!

Ed, W0SD, was reported on DXSummit by W7XU so I contacted Ed to see how his station building was coming.  He added that he was operating at around 0.25 mW TPO but has work to do before his system is ready, including the construction of an amp.  He was reported by Arliss,W7XU, who is located about 25 miles away.  At last check, Ed indicated that he was working on a slant wire antenna attached to his 190-foot tall grounded tower that uses 36 radials that are 70-foot long.  He was still working to find the 50-ohm point.  His activity marks the first transmissions on 630 meters from South Dakota under Part-97 rules.

Robert, KR7O, reported “Good conditions in the evening with quite a bit of activity on JT9.  Copied W8RUT early at 0101Z along with K2BLA and K9KFR prior to 0400Z and many other western stations.  19 decoded on WSPR including TC from K4SV, VE3CIQ, W8RUT, W4BCX and ZF1EJ No overnight WSPR reports because I was monitoring 2200M.  Heard by 17 during a short pre-sunrise transmit session on 630M.

It was a very good night at KB5NJD as noise was very low and propagation, particularly early, was very strong.  I started the session with a JT9 QSO with W7IUV.  Larry and I made short work of that contact which I followed up with JT9 QSO’s with KA9OKH, W8CDX and W8RUT.  Ken, W8RUT, and I have been attempting a QSO for quite  along time now so its great to finally get him in my log.  W7IUV reported that KA7OEI was calling CQ on 473 kHz so I began listening.  QSB was very active and Clint was up an down which was not helped by the very slow CW speed he was sending.  I called on a few peaks and it was obvious that he heard me but it took about five to ten minutes to get his attention enough to complete a QSO.  He was RST 559 on peak and he initially reported me at RST 339 followed by RST 559 on a peak.  Thanks for the new state Clint!  I worked NO3M on CW a few minutes later and we chatted and compared notes in spite of QSB.  During this QSO, Richard, K5NA, was listening from Austin, about 200 miles to the South and reported that he was hearing me and Eric and added that he should be on the air shortly.  Richard has a big station with a great 160-meter system so I expect we will see good things from him in the near future.  I listened around a bit but decided to call it a night so I could be back by 1100z.  That was optimistic but in spite of being a few minutes late I had detection of my CW on 474.5 kHz by W0YSE.  I also listened for VE7VV on JT9 but was not hearing him at all.  The path to VE6 opened around 1130z with a number of reverse beacon reports at audible levels so I suspect that future JT9 QSO attempts with those guys will have to come a bit later.  K2BLA called me from Florida at 1135Z with a nice RST 539 signal in the clear as I was listening Northeast.  I suspect Al was RST 559 to 579 had  been listening in his direction but since he was strong enough, I didn’t move the antenna.  He reported me at RST 559.  I heard NO3M calling CQ at strong levels as well around 474 kHz but did not call him.  It was a very strong session.  Stormy weather is possible tonight into Sunday morning so my evening and morning activity will be at the mercy of mother nature.

Laurence, KL7L, returned to air after stabilizing his  antenna system following damage from a falling branch to one of his capacitive top loading wires.  He had a strong WSPR session, receiving reports from 25 stations including 7L1RLL4, JA1NQI/2, JA1PKG, JA3TVF, JE1JDL, TNUKJPM  and JH1INM.  He reported seven stations including VK4YB.  He shared two-way WSPR reports with AH6EZ, K9FD, KR6LA and W0YSE.  Laurence received JT9 reports from KR7O at -19 dB S/N and he heard W7IUV calling CQ on JT9.   PSK reporter also indicated that VA7MM was reporting him.  Laurence added that it was  “A much better night from here especially TP/JA. That Merv KH6>LA went straight over the top of me but No Eu here at present…

Merv, K9FD (/KH6), had a bit of a crazy session, reporting a software problem that might have resulted in a show stopper had he not found a solution.  That would have been unfortunate as a first time ever opening between LA2XPA (or any European station) and his station was reported using WSPR.  This is a remarkably long haul (10524 km) across or around polar regions that are only seen during very quiet geomagnetic conditions.  Merv notes that this was a late report in Norway but he worked LA2XPA in 2008 on 160m at 1549z so it happens.

Using WSPR overnight, Merv reported seventeen stations and he received reports from 65 unique stations including 7L1RLL4, JA1NQI/2, JA1PKG, JE1JDL, JH1INM, TNUKJPM, ZF1EJ, VK4YB, VK2XGJ. He shared two-way reports with AE5X, AH6EZ, K4SV, K5DNL, KA7OEI, KL7L, NR6LA, KR7O, N1DAY, VE3CIQ, VK4YB, W0YSE, W3LPL, W7IUV, W8RUT and ZF1EJ.
