Current Operating Frequency and Mode

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

Remarkable night of trans-Atlantic openings as DST surges; JT9 QSO between VE3CIQ and ZF1EJ; Openings to JA were present but noise may be impeding path to VK and ZL; VO1NA CW on 477.7 kHz at PA0RDT; Midwinter 630-meter Activity Night this Saturday night in North America!

The summary from January 30, 2016 can be viewed here.

Wow – what a night!  Extremely quiet band conditions and DST values that pushed to the high positive levels meant that openings to and from Europe were probably going to be pretty good.  In fact a few first time reports were registered on European paths.  While there were areas of rain around North America, the only lightning activity to speak of was offshore in the mid-Atlantic region.

Geomagnetic conditions were quiet although the Bz is pointing to the South this morning with solar wind velocities that are lower than reported yesterday, averaging 410 km/s.  DST values spiked upward to positive values during this session which is consistent with the observed high latitude openings.  Solarham continues to report that the next coronal hole should begin to impact the geomagnetic field by late on January 31.




Joe, VO1NA, was reported on 477.7 kHz CW by Roelof, PA0RDT, who provided the following comments and screen capture:

“Joe’s signal was quite strong last night and aural copy was no problem at all. The third harmonic of the keying sidebands can be seen in the overnight Linrad plot. Best regards, Roelof”

Trans-Atlantic openings were remarkable with first time reports in Europe for WI2XJQ in Washington state on a high latitude path very near the auroral oval to LA2XPA.  WI2XRM in Florida provided reports for EA5DOM for the first time and OH1TSM received WG2XXM and WD2XSH/17.  The trans-Atlantic breakdown for each station follows:










Report details for these stations can be viewed here.

John, WA3ETD / WG2XKA, submitted these comments  from his perspective on this amazing session:

“This was a record breaking session or close to it.  XKA heard 20 (after culling out the bogus spots) and was heard by 56…activity levels appear to increase daily this season.  WH2XCR going both ways, and WG2XSV was spotted here – a rare event!  All sections of the country were definitely happening, considering the high noise levels here.  PA0O, G3XKR, G3XKR/7, LA2XPA and LA2XPA/2 spotted XKA.  The PNW was very active both ways as well.”

Doug, K4LY / WH2XZO, reported a big night as well with these comments and assessments of his receive system:

“Conditions were quite good.  I used my TX antenna for RX all night for the first time ever.  With my previous transceiver to amplifier set up, I needed a relay in order to use the TX antenna for receive, and I never did that.  With the transverter you can easily RX with the TX antenna, but need a relay for an additional RX antenna, if your transceiver exciter doesn’t provide for that.

It’s a bit frustrating and embarrassing to find that with all the work I’ve put into my Delta and Kaz receive antennas, my TX antenna works as well or better on receive!  Last night a near record 53 decoded XZO.  XZO, however, decoded a record 19, including 3 VE7s.  We’ll try the TX on RX again tonight.”


Paul, N1BUG, was listening on 630-meters with his 80-meter dipole and found above average success during this session, decoding seventeen WSPR stations including EA5DOM, WI2XJQ, and VE7CNF.  He adds that “ZF1EJ always a good signal on any antenna.”


Rick, W7RNB / WI2XJQ, had a  very strong session if for no other reason than he was the only station in the Pacific Northwest to be heard by LA2XPA during this session.  This was his first long haul DX report for his signal.  Congrats Rick!  He submitted the following comments about the session:
“WOW! What a night — the band seems to have been wide open for most points from ‘XJQ, registering two new ones on receive — WG2XKA, and WH2XZO. On Transmit it was even better with 7 new stations including a reports from LA2XPA and Eden ZF1EJ for my best DX session ever. The New stations include N7BYD, K4RCG, VE4BLZ, K7BIZ, WA9CGZ, VE7VV. I guess we’ll just keep doing what we’re doing and hope that we have more of these — This one was fun to watch — “


Rick provided reports for thirteen WSPR stations and was decoded by 45 unique stations including the previously reported LA2XPA.  Rick’s unique report details for this session can be viewed here.


Ken, K5DNL / WG2XXM,  reports that he decoded twenty WSPR stations and was decoded by 73 unique stations including OH1TSM, G3XKR, G3XKR/7, WE2XPQ, and  WH2XCR.  Ken adds, “85 decodes fm WH2XCR best +6 — Also 123 decodes fm ZF1EJ Best +10.  Condx good – The Finland station was a new dxcc fer xxm.”


Ken, SWL/K9, located in Indiana, reported that he decoded twenty WSPR stations.  Ken added, “Strong overnight propagation… 20 decodes xcr best -24 db w/ 21 decodes of xsv best -19db”


Neil, W0YSE/7 / WG2XSV, reports a great night with these comments and statistics:

“Wow, what a night for a lot of stations, including XSV, which was heard by 34 for an all time high. And, I was heard for the first time by WH2XZO, WI2XFO, and by two NEW listeners, K7BIZ, VE7VV.It is also a rare occurrence for me to be heard by WG2XKA, indicating great propagation to my east. My “2 watts” is in EIRP units (or ~ 1.4w ERP).”

“…and I heard these 12, with FIRST TIME decodes of WG2XPJ (x1), and of  WH2XZO (x10, best -23), and of  WI2XFI (x1).  Laurence, WE2XPQ came in here with 30 decodes, best at -11. “


Phil, VE3CIQ,  reported great band conditions overnight, providing WSPR reports for twenty stations and receiving reports from 43 unique stations.  Also notable was the completed JT9 QSO with ZF1EJ.  Both stations have been watching the path for a few days so its great to see an opening like this develop when both stations were awake and ready to try for a QSO.  Phil provided the following screen capture from his WSJTx console showing the QSO details:

Phil, also reported that he completed his impromptu PA mentioned in yesterday’s report.  The PA is built around a pair of 2N5302’s in push-pull configuration biased for class-B.  This was a junk box project  using  EMI suppression ferrite for transformers taken from USB cables.  He indicates that he is planning on replacing those with proper core material but is reporting no heating and better than 80% efficiency after adjusting the turns.  So far nothing has smoked with 20-watts of drive for an output of 120-watts.  Phil submitted this photo.  It’s just amazing how simple PA’s can be:

Luis, EA5DOM, posted the following comments and map for his very successful session on the RSGB-LF reflector:

“Oustanding conditions last night. Check the worldwide spots in WSPR MF by distance and you will see a lot of TA and TP (trans Pacific) spots ZF1EJ from Cayman Is. was reported in EU by LA2XPA.   I got reports from the states and as low latitudes as W2XRM in Florida and ZF1EJ.  This is the map view of my results last night.”

On the other side of the globe, trans-Pacific openings have been a bit stingy but looking at the lightning map suggests that already noisy band conditions are probably worse during this session.   The path from North America to Japan was largely unimpeded.  Trans-Pacific reports details, excluding KL7 and KH6, can be viewed here.

Roger, VK4YB, received reports for this session from VE6XH.

Ward, K7PO / WH2XXP, received reports from 78 unique stations including JA3TVF and JE1JDL.

Mike, WA3TTS, reported, “Slowly improving propagation to XCR,  NW transcon path exceptionally good overnight….”:

Mark, WA9ETW / WI2XHJ, reported that he decoded 17 WSPR stations during this session but WH2XCR continues to elude him.

Andy, KU4XR, operated OPERA and WSPR overnight and submitted the following statistics and comments for the session:

“Garry got in on a test run last night .. It was on purpose.. I asked John – BDQ if he would run a combo OPERA – WSPR test on the same frequency .. Not to see which one was best, but rather to see how many ” MORE ” decodes of WSPR I could get from him on a quiet frequency .. My belief that I am ( lose-ing ) several WSPR decodes due to receiver desense became very evident when I saw 24 WSPR decodes this morning .. Even on the best night on the WSPR frequency, I have only gotten 7 to 8 decodes.  OPERA ” detected ” 1 more transmission in Deep Search than WSPR, but only because it was 45 minutes into daylight here .. Test results are below ..Thanks John – VE7BDQ for helping me with this test … and 73 to all:”


Don’t forget!  This coming Saturday night in North America will be the 2nd Annual Midwinter 630-meter activity night.  The dates and time have been mis-reported in a few locations but Steve, VE7SL, has it correct here on his blog.  There will be cross band  activity between Canadian stations and the rest of the world as well as experimental stations in the US looking for QSO’s and operating beacons.

This session was fantastic all the way around.  Had it not been for the coincidence of the CQWW 160m CW contest I would have spent some time calling CQ but I figured all of the guys I would normally work were  exhausted and probably not up for more CW on 472.  It seems that a number of those guys transitioned to 630-meters after the contest as activity numbers were at record high levels.  WSPR activity was very good and my receive totals exceeded 1000 for the first time this season while my transmit total exceeded 2500 over the same 12-hour time period.  Openings to G3XKR, G3XKR/7 and F1AFJ on the trans-Atlantic path, WE2XPQ on the high latitude path and two-way reports at WH2XCR highlighted my session.  These are the nights we wait for and dream about through the summer.  My WSPR transmission report details for the session can be viewed here and my WSPR reception report details can be viewed here.

WG2XIQ 24-hour WSPR activity


It was a record night of activity on 630-meter WSPR as Roger, VK4YB, reported that 137 MF WSPR stations were observed on the WSPRnet activity page at 0545z.  Roger adds that its only a matter of time before we reach 150 stations.  Just unreal!

Regional and continental WSPR breakdowns follow:

Eden, ZF1EJ, reported that this session was his “Best night ever…”  He was decoded by 41 unique stations including LA2XPA/2 and provided reports for 22 unique stations including EA5DOM.  Eden shared  two-way reports with WH2XCR and  also completed a JT9 QSO with VE3CIQ that was reported earlier.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, pushed his signals toward JA during this session, with reports from JA1NQI, JA3TVF, JE1JDL, and JH3XCU.  Laurence also shared two-way reports with WH2XCR with receptions into the south central US.  His JA and KH6 report details can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, received plenty of reports with JA and VK stations, including JA1NQI, JA3TVF, JH3XCU, and VK4YB (two-way).  Merv also shared two-way reports with ZF1EJ and provided reports for VK3HP and VK3ELV.  As previously reported, two-way reports were also registered in the eastern US at WG2XKA as well as WE2XPQ.  This was a very strong session for Merv.  His report details can be viewed here.
