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

Current Operating Frequency and Mode

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

Good late evening JT9 activity as band stabilizes after 0300z including QSO’s for new station KA7OEI in Utah; Kp spikes to unsettled levels which may have given spark for decent propagation including a few transcontinental openings; WA3ETD two-way CW QSO with NO3M; Path opens again for KL7L -> JA1PKG on WSPR

Continental North America was mostly lightning free but rain static reported from a system in the Great Lakes region increased noise levels for a number of stations in the Midwest.  Strong lightning-rich storms off of the southeastern US Atlantic coast also offered quite a bit of noise for the mainland until those storms were in full sun.  The storms were also reported to be causing problems in coastal Massachusetts this morning.  Northern Europe once again experienced evening storms with a few lingering into the morning and  the western Pacific continues to experience seasonal storm conditions from southeastern Australia into Indonesia.  Japan is also surrounded by at least one system containing lightning but those stations seem to be making the best of the situation.

Geomagnetic conditions reached unsettled levels for a single reporting period over night followed by periods of elevated-quiet.   The Bz is pointing slightly to the South this morning and solar wind velocities are averaging near 395 km/s, up from the previous session.  DST values have generally improved with a trend towards the centerline, which was achieved by both of the presented measurements.  A slight decrease accompanied the unsettled Kp levels reported previously but this episode may have provided a necessary spark for relatively good propagation late last night and this morning.




Propagation was very good later in the evening as the band settled down.  Activity was down overall for this session, probably the result of many stalwart operators working the CQWW CW contest this weekend in addition to Thanksgiving holiday hangover.  Propagation remained good enough for transcontinental openings to develop overnight and a number of QSO’s were completed as a result.  QSB remained very active and was more evident during the evening than this morning.

Reverse beacon network reports for the session follow (note that many RBN nodes have probably been repurposed and refocused for CQWW CW contest this weekend):

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!):

David, G0MRF, reported a good night of FT8 QSO’s  and also some additional help for IC7300 users in his following comments and statistics:

“Very nice to see a few people active this evening making QSOs on 630m.

I managed to work  Ian G4GIR from home with a minimalist 4W  TPO  at my end using FT8.  Sent +6 to Ian, received -20After QSYing to the radio club for our regular Friday night meeting, we managed 2 way QSOs with.
DL6TY      FT-8     sent -11  received -19
EA4GHB   FT-8     sent -17  received -10   (1200km)
EA4GHB  JT-9      sent -25 received  -22
and finally DG3LV where we struggled through some deep QSB, but finally manage to complete using JT-9  with -23 and -22 reports.
A quick FYI for IC7300 owners.  If you go to ‘settings’ and ‘function’. The menu allows you to switch the medium wave attenuator out of circuit. – Thanks Philip G7JUR for that tip.”

Eric, NO3M, completed  a CW QSO with WA3ETD and a JT9 QSO with KA1R in Massachusetts (latter is a second-hand report).

Phil,  VE3CIQ, completed JT9 QSO’s with WA3ETD and K9KFR.

Bob, K9KFR, completed JT9 QSO’s with WA9CGZ, K2BLA, VE3CIQ, WB0DBQ and WA3ETD.

Neil, W0YSE, reported a new broadband static-type noise in his neighborhood that he is investigating.  Even with the noise, Neil found success and submitted these comments and statistics for the session:

“I had two JT9 Q’s last night. VE7SL (s,r) -24, -14 with a lot of QSB. At one point Steve was at a -14 also.

The other Q was with Rob, KC0B in CO (s,r) -18, -20. 

Some others I saw on my JT9 screen were N1VF, W7IUV, CF7MM, VE7CNF

Most of the JT9 activity seems to start around 03z until about 0430z, and then an occasional CQ here and there thru the rest of the night.

Toby [VE7CNF] tried to hear my WSQcal signal but was not able to even see me on the watefall with his WSQcal program nor with his other SDR waterfall. Rain at his end hampered his reception. We will try again some time. 

As for WSPR this session, I was heard by 33, including Merv K9FD (/KH6), but heard only 5, including Merv. “

John, WA3ETD, completed a CW QSO with NO3M and JT9 QSO’s with K9MRI, VE3CIQ and K9KFR, the latter of which was subject to strong QSB during their first QSO attempt followed by a solid QSO completed about 30 minutes later.

Al, K2BLA, reported a morning JT9 QSO with K9KFR.  During the evening he completed a JT9 QSO with WB4JWM.  Al reported thirteen WSPR stations and received reports from 49 unique stations.

Rob, NC0B, completed JT9 QSO’s with K9SLQ, WB0DBQ, W9XA, VE7SL, N1VF, K9KFR, KA7OEI and W0YSE.   Rob indicated that he heard NO3M’s half of a JT9 QSO with KA1R.

Clint, KA7OEI, a new station in Utah, completed JT9 QSO’s with VE7SL, NC0B and W7IUV.

Larry, W7IUV, completed a JT9 QSO with KA7OEI and reported VK4YB’s WSPR signal.

The evening session was slow at KB5NJD but I managed JT9 QSO’s with W9XA and K9KFR.  CW activity was low but not unexpected given the concurrence of the CQWW CW contest.  The band was once again a bit noisy to the East and quiet to the West.  I never heard K4EJQ around 472.3 kHz but he was reported to be there.  This morning’s CW session yielded similar results although noise decreased significantly and rapidly after sunrise along the Atlantic coast where storms were present.  I’ll be back tonight, probably alternating between JT9 and CW through the evening after dark.  That approach has been active in filling in holes in my “station’s worked” list.

Hideo, JH3XCU, submitted this link detailing DX -> JA decode totals and DX -> JA S/N peaks for the session, as reported on the Japanese language 472 kHz website.

Robert, KR7O, reported “Average conditions, but some good western JT9 activity.  Heard 14, nothing beyond the typical 2400km stations.”  Robert’s session best DX includes:

K9FD 85 spots, -1

KL7L 44 spots, -18

VK4YB 11 spots, -20

Trans-Atlantic WSPR report details can be viewed here.  The trans-Atlantic WSPR summary follows:


Ken, K5DNL, called CQ with JT9 at one point during the evening to no avail.  He received seventeen WSPR stations and received reports from 81 unique stations including eleven Canadian stations.  He shared two-way WSPR reports with K9FD (/KH6).

Stefan, DK7FC, reported that he received a communication from Martin, YV5MAE, who indicated that he has been off air for a while due to a lightning strike that impacted his station and Internet.  Martin recently returned to receiving 630 meters and reported to Stefan that he decoded the following WSPR North American stations on November 23, 2017:

171123 0112   2 -28 -1.2   0.475790  K5DNL EM15 37

Mike, WA3TTS, reported that, using WSPR, he “Hrd 22 overnight on 630m including K9FD, N6GN, KA7EOI…

Keith, K0KE, reported that he “Let WSPR receive run all last night, decoded K9FD numerous times over course of night, highest signal read was -14 at 0910Z  Otherwise just stateside stuff..”

Ken, SWL-EN61, located in Indiana, reported daytime activity of K5DNL and WD8DAS in addition to comparisons with the “racing strip” that is present in the WSPR window.  W5EST also noted K5DNL during the day on a ground wave path.
