Current Operating Frequency and Mode

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

Very strong session for JT9 in North America and Europe as N1BUG and NO3M work G3KEV again and a number of North American stations are heard ”across the pond”; Many other’s make attempts for trans-Atlantic QSO’s; ”Toggle-switch” QSB dominated the session and path reciprocity took a lot of patience to find; Great transcontinental openings and a number of stations work new states; EA5DOM -> FR5DH; Trans-Pacific paths remain pretty good but are noise limited.

Lightning was active from Hawaii to Mexico with a few isolated storms in the Gulf of Mexico and Atlantic.  The bulk of storm activity in Europe was located in the western Mediterranean with a few isolated storms in the UK.  Australia experienced activity along the west coast and the southeast coast which made listening in the storm-free areas of the continent difficult.

11-hour worldwide lightning summary

 

Geomagnetic conditions were at quiet to elevated-quiet levels. The Bz is pointing to the North this morning and solar wind velocities  are averaging near 340 km/s.  DST values have generally been at positive levels but today’s presented measurements are telling different stories.

 

 

 

Propagation was very good, particularly on transcontinental paths.  Fast QSB was more active than the previous session and while trans-Atlantic openings were very good, the QSB may have left many thinking that the band was not as good as the previous session.  Trans-Pacific paths were good but noise in Oceania limited reporting of DX stations.

Reverse beacon network reports follow:

 

Jim, W5EST, submitted the following screen captures of his WSJTx console showing JT9 activity observed at his station in Little Rock, Arkansas:

Rolf, LA2XPA, received a number of JT9 stations during this session, reporting “Even more stations were received tonightStrongest was N1BUG peaking at 0301UTC SNR -12dB.

Rik, OR7T, reported that he “…had 4 copies in 20 minutes at AA1A arround 23 UTC, would heve been enough for a QSO.”  Rik made calls to NO3M and N1BUG in some cases exchanging partial reports but no QSO’s were completed.  That in itself is a remarkable feat as Rik is reporting to operate at 700 mW ERP.  Rik also noted that “Condx are not as good as last night.” and just prior to bedtime, he posted these receptions:

Rik added this morning that “Last night we close to comlete a QSO despite the rather poor conditions, so I am optimistic for a future QSO.  There often is a short propagation peak at NA sunset, maybe we can try to take advantage of that.”

David, G0MRF, reported reception of one of the attempts between NO3M and DK7FC from DK7FC’s perspective:

Jan, LA3EQ, reported that “N1BUG and NO3M came in first part of the night and then “puff” dx condx gone here in JO28XJ Norway”  One of those reports for N1BUG was quite early:  2303 -26 0.6 1327 @ CQ N1BUG FN55  !U.S.A.

Stefan, DK7FC, reported that,

“Indeed, last night was quite impressing. From my observation, February is the best DX month, from ULF to MF.

I guess it’s more than half a year ago that i visited the 630m band. The input modification of my PA worked much easier than expected.  It was very cold outside, the losses were low!

Got regular JT9 reports from 15 stations > 5000 km distance.

These were received from the NW/SE loop on the tree. From the city, there was no TA reception at all.  Late in the night, better said early in the morning, i got the idea to play with SpecLab as a pre-noise-reduction-stage in front of WSJT-X. Maybe a band filter, multi-notch filter and noise blanker would have helped? It was to late and i’ve been tired. Went to bed at 5:00 AM local time!!…”

Roelof, PA0RDT, reported VO1NA’s CW on 477.7 kHz overnight, noting that “propagation was worse last night.  Yes, the beauty of LF propagation is that not a single night is the same as the previous one. It should be rather boring if it was.”

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!):

Paul, N1BUG, reported another JT9 QSO with G3KEV.   He also worked VE7CNF using JT9 on a very long transcontinental haul and K9KFR with CW.  Paul submitted these comments to the RSBG reflectors.  Its sounds like there will be more action tonight, propagation permitting.

Eric, NO3M, worked G3KEV for a second consecutive night and like many others, spent considerable time trying to get DK7FC’s attention, exchanging partial reports through the evening.

Mal, G3KEV, completed JT9 QSO’s with NO3M and N1BUG and posted the following comments this morning:

“I checked the band a  couple of times later on during the night, early morning and you and NO3M were calling DK7FC but he was not responding, however both your signals were fairly steady for some time.  Might be around again tonight and if propagation was favourable maybe we could try FT8.  It is also possible to QSO using CW or QRSS.”

Al, K2BLA, reported that he “Worked KB5NJD, K0KE, K9MRI, last nite on JT9 and WA3ETD this AM. On WSPR heard 21 including EA5DOM, and G0MRF. Heard by 63, one of my higher tallies, including LA2XPA at an amazing -17. T storms finally moved off the coast and noise was low.”

Tom, WB4JWM, reported that this was a “Busy night, worked….VE7SL,W7IUV,N1BUG,K3MF, K0KE,K9MRI, K9KFR, WA9CGZ on JT9”

Steve, VE7SL, reported JT9 QSO’s with K3MF, WB3AVN and W1IR.  Steve also worked VE7CNF while Toby had the PA turned off, resulting in only 0.5w ERP.  Steve completed CW QSO’s with K3MF and K9KFR.

Wayde, K3MF, had an exciting night, reporting “What a night! I heard into EU and was received there. Worked VE7SL for new dx on JT9 then at 0550 worked him on CW 449 both ways.”  Wayde also worked N4WLO for what was likely a new state and W7IUV on a long transcontinental opening.  He was heard on JT9 by LA2XPA.

Bob, K9KFR, completed a JT9 QSO with VE7CNF.  He spent time calling DK7FC on JT9 and he worked VE7SL and N1BUG using CW.

Al, WB0DBQ, reported a JT9 QSO with WA9CGZ.

Bob, WA1OJN, completed JT9 QSO’s with W7IUV, WB3AVN and KB5NJD.

Keith, K0KE, completed JT9 QSO’s with WB3AVN, WB4JWM and K2BLA.  He called N4WLO on a few occasions but no completed QSO was reported (at this time).

Joe, K9MRI, completed JT9 QSO’s with WB4JWM and K2BLA.

Toby, VE7CNF, indicated that he had “JT9 QSO’s with N1BUG (new for me), W7IUV, K0KE, K9KFR.  Also worked VE7SL via FET feed-through with the TX PA supply turned off.

Larry, W7IUV, reported more “toggle-switch” QSB but he completed JT9 QSO’s with K3MF, WB3AVN and WA1OJN, who was Larry’s state #25 on 630 meters.  He was hearing WA3ETD in Vermont but the path was not reciprocal at that time.

Neil, W0YSE, operated WSQ for part of the evening with very good results.  He offered these details:

“I had a nice long chat on WSQ last night with Mark VE7MM. Mark had me move up-band another 900 hz so that he would be away from local JT9 spurs for better copy. It seemed to work pretty well as copy was apparently 100% on his end after that. Mark was running about -10 dB here most of the time. So, for next session I will move my dial to 476.5 kHz (RF at 478.0) for my WSQ operations.

I also decoded John VE7BDQ a few times last night, also around -10 dB level.

Then, this morning I received an email from Mark KU7Z in Ogden UT. He was receiving both Toby’s and my WSQ beacons at -19 dB around 0600 CST.

Also got several JT9 spots of Ken K5DNL along with the  regular PNW stations.”

Ken, K5DNL, operated WSPR overnight, reporting twenty stations and receiving reports from 88 unique stations including G0KTN, G0MJI, 2E0ILY, G0VQH, F1AFJ, G0LUJ, F6GEX, PA0RDT, F59706, EA1BNF, KL7L, YV7MAE and eight Canadian stations.

Luis, EA5DOM, was reported  by Pascal, FR5DH using WSPR.  He submitted these comments and statistics for the session:

“…Just as it happened in other seasons with Michel FR5ZX I was the only station spotted and just few times. Also very early.

2018-02-08 20:24              EA5DOM             0.475609              -27         0             IM98xn                1             FR5DH  LG78pw               8783km
2018-02-08 20:36              EA5DOM             0.475609              -27         0             IM98xn                1             FR5DH  LG78pw               8783km

Joined the JT9 party but just to make QSO with Stefan and Mal. Saw JT9 decodes in PskReporter from AA1A and VE9GJ but no copy here. So, the rest of the night I was in WSPR

TA results during the night were very good. Reacing inside US up to Minnesota, W0DJK. Florida, K2BLA and Venezuela YV7MAE.

To the East RN3AGC in Moscow. I think is the best “spots map” I have got so far, mostly due to the new stations QRV.  Not bad for only 80W to antenna. But in a 90m vertical, top loaded and top feeded.”

It was a fun night of JT9 at KB5NJD.  I completed QSO’s with N4WLO, who was a new state for me.  As he does not CQ, I decided to call him and he responded.  I also worked WA1OJN for a new state.  WB3AVN rounded out the evening.  JT9 activity was unlike anything I had ever seen, in some cases with ten calling stations in a cycle.  Transcontinental openings were strong and a few Europeans were receiving reports as close as the Midwest.  Its too bad that we did not have this much interest a month ago.  Perhaps this is what we needed to get people excited and working on their systems this coming Summer for the next season.  I look forward to tonight and may make a few calls on CW if the band is quiet enough.

Martin, YV7MAE, reported ten WSPR stations including EA5DOM.

YV7MAE session WSPR summary

 

Laurence, KL7L, indicated that he had an entire screen of JT9 reception reports and call signs by the late evening, including “K5DNL, VK4YB, VE7CNF (QSO attempt, but no cigar), K0KE (called), VE7SL, VA7MM, NC0B, VE7BDQ, N1VF, VE7VV.”  Using WSPR in a receive-only capacity overnight, Laurence reported eight stations.  This morning he transmitted a big, receiving reports from JH3XCU.  He also noted that “W1IR was new rx for me last night – promising over 5100Kms.”  Vermont to Alaska is a tough path.

KL7L session WSPR summary

 

Roger, VK4YB, indicated that “QRN was a little too close to be any good for receiving. TP was late starting again. My FT8 QSO with VK4AQJ was copied by VK3ALZ and VK5FQ. JT9 was copied by KL7L, VE7BDQ and VE6XH.”  Using WSPR, Roger reported two stations and he received reports from 23 unique stations including 7L1RLL4, JA1PKG, JA3TVF, JA5AEA, JA8SCD5, JE1JDL and JH3XCU.  Roger shared two-way reports with VK4AQJ.  N1VF reported a single JT9 transmissions from Roger at 1308z.
