OFF AIR but returning after dark on Saturday night

Another night of different propagation as geomagnetic activity continues to stabilize; Trans-Pacific showing life on E / W paths but N / S less impressive; Night one European MF QRSS QSO party; UR5FFC -> FR5ZX; WH2XZO -> N1BUG 75 minutes after sunrise

– Posted in: 630 Meter Daily Reports, 630 Meters

Like yesterday this session showed another side of propagation.  The band wasn’t poor but openings were different and while highly productive North / South openings were observed during the peak of the most recent storm, East / West openings have returned as the geomagnetic field relaxes, providing good Asian coverage for North America at the expense of trans-Atlantic reports.  That’s what the data shows but we may observe variations and exceptions to this as the morning progresses and conditions have a chance to change once again in the Pacific.  Its like they say about Texas weather – if you don’t like it, wait a minute because it will change.  As I am writing this, Paul, N1BUG, in Maine is reporting remarkable full sun WSPR decodes of WH2XZO in South Carolina.

It was a quiet night and morning so everyone seemed to have a good chance to hear or be heard by someone.  We are expecting thunderstorms here this afternoon, overnight and tomorrow so this morning’s activity may be the last for a few of us for a few days.


11-hour North American lightning summary


Geomagnetic conditions have stabilized a bit to elevated-quiet levels as we distance ourselves from the recent Kp spikes.  The Bz is currently pointing slightly to the South but solar wind velocities are beginning to trend downward, with some periods reporting below 600 km/s and generally all recent reporting periods now below an average of 610 km/s.  DST values are beginning to smooth although the re-scaled Australian graph suggests periodicity to the data spikes.







Trans-African openings did not extend as far into Europe as in previous sessions but the streak continues as UR5FFC was received by FR5ZX.  Another call sign (8Q7IO) was also reported but the data suggests it was  phantom data born from noise and signal mixing.




UR5FFC, as reported by FR5ZX


The MF QRSS QSO party was this weekend and night one is complete.  A few QSO’s were reported and even more signals were only received.  Given the  slow nature of QRSS, completing many QSO’s can be challenging in a single session.  A number of stations indicated that they would be active in night two (tonight!) so I suspect more details will become available.  So far the raw reports follow:

Mal, G3KEV reported on the RSGB-LF reflector, “CQ DE G3KEV QRSS/DFCW NOW 476.150 Khz” early in the event.  He promptly reported “IQ2MI now visible in QRSS mode OOO copy”  Mal indicated that he was using “COMPUTER/SPECLAB 700 Hz tone TX / TS590 /USB / AMPLIFIER RX VISUAL ALSO SPECLAB.”  Mal also reported a QSO with G3XIZ: “g3xiz de g3kev tnx Chris qso qrss3 u are 20dB sig”

Andy, F6CNI, reported Mal’s QSO with G3XIZ, “I see your QSO with Chris, and now your CQ’s. Your signal on 476152.5 is strong ! Chris signal was also easy to decode on day time. Congrats !”  Andy added this morning:

I was only receiving during this QRSS party. I had bad local QRN and the cdx seems not very good. My SWL results : 12 Stations heard and 7 countries ( DK – F – G – I – LA – SP – VO ).  I hope many stations be QRV next saturday during the CW party !  Best 73 de Andy.”

Domenico, IZ7SLZ, reported, “A very good copy of DK1IS in JN80NU. Congrats Tom. I will join the party tomorrow evening, btw my receiver in on-line here: http://www.qsl.net/iz7slz/OPDS/grabber.jpg  GL. Domenico, iz7slz”

Joe, VO1NA, had planned on joining the action but due to a QSX related problem, he remained solely on 477.7 kHz.

Markus, DF6NM, reported that his MF grabber was active and apparently a significant number of signals were observed there.  The grabber can currently be viewed here.  This morning, Markus reported the following:

“Last night, good QRSS / DFCW signals were picked up here from IQ2MI, F4DTL, F6ACU, G3XIZ, DK7FC, G3KEV, I4DXW, SO5AS, DK1IS, and traces from VO1NA on 477.7 kHz.”

Laurence, KL7L / WE2XPQ, setup an MF grabber window.  He explains:

“Although over the pole isnt particulary good at the moment Ive put up a  temp MF window here in Alaskahttp://kl7l.com/MF00000.jpg   – subject to blocking etc when Im going for it on 137/475 –  signals from the Eu utility stations arent too shabby at the moment on 137/135kHz  at local midday- wspr2 rx also on 475m,and rx windows in usa and rest of the world viewable on http://kl7l.com etc”

I suspect there will be more reports forthcoming and with the CW QSO party next weekend, a lot more stations may be active.  I will report what is submitted.

Neil, W0YSE/7 / WG2XSV, reported that Toby, VE7CNF, was painting HELL on his waterfall very nicely during the evening session:




Paul, N1BUG, reported that he decoded WH2XCR as well as WH2XZO at 75 minutes after sunrise with the entire path in full sun at a distance of 986 miles.  Tis the season!

Neil, W0YSE/7 / WG2XSV, made some upgrades that helped his signal.  He explains:



WG2XSV session WSPR activity

Rick, W7RNB / WI2XJQ, characterized this session as more like normal at his station.  He decoded eight WSPR stations and was decoded by thirty one unique stations including ZF1EJ.  Rick’s unique report details can be viewed here.

Doug, K4LY / WH2XZO, reported good conditions, decoding ten WSPR stations and receiving reports from 38 unique stations.  He adds that he QRTed before seeing comments from Paul, N1BUG, regarding his reports of Doug so long after sunrise.

Mike, WA3TTS, reports, “Back to more normal numbers of WH2XCR decides, but the transcontinental path to the NW was enhanced to some locations…”



“I ran a split IF out of the LF/MF converter also monitoring 2200m wspr2.for 179 WH2XND decodes, with many CW IDs heard, best wspr2 at -4 SNR.  73 Mike wa3tts”

Trans-Pacific reports for the session are aggregated here.

Ken, K5DNL / WG2XXM, reports that he received decodes from 51 unique stations including VK4YB and WE2XPQ.  He also received 103 reports from WH2XCR, best at +3 dB S/N, at a distance of 6003 km.

Ward, K7PO / WH2XXP, received reports from 65 unique stations, including DX reports from 7L1RLL4, JA1NQI-2, JA1PKG, JA3TVF, JE1JDL, JH3XCU, VK2XGJ, VK4YB, and ZL2BCG.

Larry, W7IUV / WH2XGP, reported that operator error left him off air overnight but in spite of the incomplete session he did receive reports during the evening.  Those reports can be seen in this rendering provided by NI7J  Note that Larry’s other receiver, designated as W7IUV, decoded VK4YB several times over night:

Roger, VK4YB, provided DX reports to WG2XXM, WH2XXP, WH2XCR and WE2XPQ. He received DX reports from W7IUV, JE1JDL, VA7JX, VE7BDQ, VE7CNF, ZL2IK and VK7TW.  Roger also indicated that storms were approaching Brisbane and that an otherwise good night might be ruined.

Like the previous session, I did not have high expectations of finding a CW QSO in the evening or this morning since this is CQWW-CW contest weekend on HF but I continue in the interest of consistency.  WI2XBV has been making adjustments to his system so that it is “QSO-worthy” and I expect that I will be hearing his call sign returning to my CQ any day now.  Band conditions were very quiet and signals were strong, perhaps not quite as good as the previous session but nothing to complain about.  The band is changing on the approach to the Winter solstice so every night will likely bring something new.  My WSPR transmission reports can be viewed here and my WSPR reception reports can be viewed here.


WG2XIQ 24-hour WSPR activity


Activity on the band was very high once again.  WG2XXM reported at 0051z that 105 MF WSPR stations were observed on the WSPRnet activity page.  How high will it go?

Regional and continental WSPR breakdowns follow:


North American 24-hour WSPR activity



European 24-hour WSPR activity



African 24-hour WSPR activity



Central / Asiatic Russian 24-hour WSPR activity



Japanese 24-hour WSPR activity



Australian 24-hour WSPR activity


Eden, ZF1EJ, had a strong night, reporting VE7CNF in British Columbia and WI2XJQ in the Pacific Northwest in addition to WD2XSH/15, WG2XIQ, WG2XXM, WH2XCR, WH2XXP, WH2XZO, and WI2XBV.  Eden’s report details for these stations can be viewed here.


ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, experienced two-way openings with VK4YB and WH2XCR, and typical openings around North America.  No JA reports were observed during this session so evidently the recent storm conditions were providing a necessary enhancement for those openings.  Laurence’s DX report details can be viewed here.


WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, had another strong night, with reports in Maine at N1BUG.  Merv continues to have openings to JA1NQI-2, JA1PKG, JA3TVF, JE1JDL, and JH3XCU.  He also shared two-way reports with VK4YB and was received by VK2XGJ.  Curiously, WE2XPQ is displayed in the South Pacific instead of Alaska and is representative of intermittent map rendering problems observed on WSPRnet.org.  Hopefully they get those problems resolved quickly.  Merv’s DX report details can be viewed here.
