Current Operating Frequency and Mode

OFF AIR but hope to be back by 1115z Saturday morning if I don't oversleep

Evening CW explosion in North America sounds like a QSO party with big signals, mostly low noise, and wild QSB; K2BLA takes maiden voyage with new CW transmitter; Big night for trans-Atlantic openings but high noise impacts trans-Pacific reports in Oceania

The UTC amateur registration database is here.

HERE are a few mode-specific comments addressing where modes are located now and probably where they are best placed in the future

Curious about who is on the air making two-way QSO’s? Roger, VE7VV, is maintaining this list. If you complete QSO’s, be sure to let us know so he can add you to the active operator list.

Storms were a dominant feature in parts of the Midwest into New England overnight and this morning.  A few isolated storms were also present in the central and western US.  Strong storms continue to  across parts of Europe, particularly southern region.  Strong storms continue to impact Australia and particularly coastal areas of the sea of Tasman.  Remarkably, it was almost deafeningly quiet here in North Texas during the evening and this morning, which enhanced the operating experience for me possibly more than any other night since the band opened to amateurs.

11-hour worldwide lightning summary

 

Geomagnetic conditions are currently very quiet although another G1 storm may be on the horizon  according to Solarham. The Bz is pointing slightly to the North and solar wind velocities are averaging near 370 km/s.  DST values remain near the centerline at negative levels.  The Kyoto measurement was not accessible today.

 

 

Propagation was fantastic during the evening session once the band settled down.  QSB was very active through the first hours of darkness but signals were reaching true RST 599 levels for many stations that I was hearing and working from here in North Texas, only to have them disappear into the noise again after a brief peak.  It meant keeping transmissions short.  It helped that there was a tremendous amount of activity on the band during the evening to test and validate propagation.

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!):

“Basil”,W8CDX, completed CW QSO’s with K0KE and and attempted a QSO with K9SLQ that ended in QSB.

Eric, NO3M, reported his three week totals as follows:  81 QSO’s with 35 unique stations including  43 CW, 2 SSB, 30 JT9 and 6 FT8.  During this session Eric completed CW QSO’s with K0KE, KB5NJD and K2BLA and a  JT9 QSO with W7IUV.

Wayne, K9SLQ completed JT9 and CW QSO’s with KB5NJD.  Wayne attempted a CW QSO with W8CDX but apparently QSB prevented reports from being exchanged.

Keith, K0KE, completed CW QSO’s with VE7SL, W7IUV, W8CDX, NO3M, and KB5NJD.

Larry, W7IUV, completed JT9 QSO’s with KB5NJD, K5DNL and NO3M.  He worked K0KE and NO3M with CW.  He received a JT9 reception report from KL7L at 1219z at -29 dB S/N.  Larry added that his 3-week breakdowns include 62 QSO’s with 31 unique stations.  On WSPR this morning, Larry reported VK4YB as W7IUV/W.  He also received a report from JA1PKG/2.

Ken, K5DNL, reported JT9 QSO’s with W7IUV, K9SLQ and VE7VV.  On WSPR overnight Ken decoded nineteen stations including K9FD (/KH6) and VK4YB.  Ken received reports from 91 unique stations including K9FD (/KH6), ZF1EJ and ten Canadian stations.  Ken also reminds us to please check the WSPRnet activity page to make sure stations are not on top of one another.  Co-located stations benefit no one.

Steve, VE7SL, completed a CW QSO with K0KE and a JT9 QSO with Ben, N1VF.  Steve noted that Ben does remarkable well from a station that is located in the city.

Al, K2BLA, completed his CW transmitter and was on the air making QSO’s last night!  Al worked me (KB5NJD) and NO3M through local QRN.  Al and I also completed a CW QSO this morning at RST 589 / 559.     He also operated some JT9 but I do not see any references from the ON4KST chat transcript to suggest that he posted any QSO details.  On WSPR Al reported thirteen WSPR stations and he received report from 56 unique stations with fifteen stations in excess of 3000km away from his QTH in Florida.  Those stations were located in VE2, VE4, VE6, and VE7.  Al shared two-ways WSPR reports with K9FD (/KH6).  He also submitted the following details about his new CW station and I bet he would be open to questions about the details for those that might be interested in replicating:

“The design was driven from what was in the junk box. It uses a VFO that operates at twice the output frequency at around 950 kHz. Since it is not in the 630m band it is not received by the receiver and runs continuously to minimize frequency drift. The VFO is varactor tuned with t ten-turn potentiometer which gives a nice tuning rate and ten turns to play with. I used this technique about 40 years ago for a project in one of my books.
When transmitting, the VFO is divided by 2 with a flip-flop and then ANDed with the 950 kHz VFO to produce 25% duty cycle in-phase and an out-of-phase digital signal to drive the MOSFET gate driver ICs. The amp is push-pull. There is some adjustment that can be made to optimize the duty cycle of the output MOSFETS.
For spotting a separate flip-flop is activated to produce the on-frequency signal and is coupled to the receiver input. This low power signal will not radiate anything as there is a preamp between the antenna and the receiver and this is injected after the preamp. The preamp is not so much for its gain but to reduce all the strong out-of-band signals in that frequency range. Even though the Icom 756 PRO II receiver covers 630m its receiver performance is pretty bad unless some good bandpass filtering is provided.
The amp is modulated with a P-channel MOSFET to eliminate key clicks. The Vdd is nominally 28 volts and is adjustable. Remember, this is a stand-alone xmtr and is not tied to the 13.5 volt power supply required for the PRO II.”

As has been the case for the previous few sessions, the band was slow to open at KB5NJD on some paths until about an hour of darkness was achieved.  NO3M was calling CQ on 473 kHz CW, peaking intermittently around 0030z.  I called him as the band was on the way down and we missed one another until around 0037z when we completed a pretty solid exchange of reports.  Learning my lesson from other QSO’s I cut this QSO short but in reality the band was probably stable enough for both of us to carry on for a few minutes at least.  The band was quiet but QSB was active from time to time.  I was able to sneak JT9 QSO’s with K9SLQ and W7IUV and then caught K9SLQ for the second time on CW in less then 24-hours.  Keith, K0KE, made an appearance on the band, making contacts with four stations by the time that he and I had a chance to chat again.  He was a very strong RST 599 but QSB took him away only to bring him back two-minutes last while CQing again.  I sent “QSB 73..” and left it at that.  I think Keith worked VE7SL shortly afterward so the band was really making the rounds.  I heard a station calling CQ on 474.5 kHz from the other room, a loud station, but I was distracted enough to not copy who it was.  It wasn’t any fist that I recognized, however.  Coming back into the ham shack, the station began calling again and it was K2BLA!  I’ve been waiting for a few years to work Al on CW so this was a treat.  As he was finishing up his CQ, I heard another carrier zeroing in.  I made a quick call and Al and I exchanged reports through QRN in Florida.  We signed fairly quickly and Al went on to work Eric, NO3M.  The carrier “swooshing in” was Eric coming on frequency and lining up the transmitter and receiver.  I worked Al again this morning with RST 579 / 579 reports with low noise and high stability.  The band was good but the time change  creates problems for everyone so there will be some realignment of operating schedules in the coming days and weeks.  With earlier darkness in the evening there may be more possibility to take advantage of nice evening openings without staying up until midnight.

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.

Roger, VK4YB, reported extremely high noise, which kept him off of JT9 due to the likely inability of hearing anything.  Transmitting with WSPR, Roger indicated that it was a “Good WSPR session. Heard 2, heard by 29 (21 DX), best John, N3FL,(15308km), then Ken, K5DNL.”  Roger received reports from JA1PKG/2, JA3TVF, K5DNL, KL7L, KPH, KR6LA, KR7O, N1VF, N3FL, N6GN, N6SKM, TNUKJPM, VE6JY, VE6XH, VE7BDQ, VE7CNF, W6SFH and W7IUV/W.  He shared two-way reports with K9FD.

Robert, KR7O, reported no sign of KL7L during the session but he reported VK4YB  thirteen times between 1114z – 1230z, best report at  -18 dB S/N.  Robert also reported that K9FD was heard all night best at -6 dB S/N.  His longest transcontinental WSPR report was of W1IR, providing four decodes, best at -24 dB S/N.

Roger, VE7VV, reported “WSPR RX last night, 8 uniques, 6 of those over 2500 km, including K2BLA (FL) & W1IR (VT). Amazing long skip!  Also some amazing one time QSB peaks. W7IUV at +20 and K5DNL at -5.”

Doug, K4LY, decoded nineteen WSPR stations through moderate QRN, indicating “no real DX”.

Dave, N4DB, reported that he decoded eighteen WSPR stations with W7IUV as his best DX.

ZF1EJ session WSPR activity

 

Laurence, KL7L, indicates that he was in a receive-only capacity overnight, reporting  five WSPR stations including VK4YB.  He transmitted a bit of WSPR this morning, receiving reports from twelve unique stations including 7L1RLL4, JA1NQI, JA1PKG/2, JE1JDL, JH3XCU and TNUKJPM.  He shared two-way reports with KR6LA and K9FD.  Laurence also called CQ for a bit with JT9 this morning but indicated that he had no known takers.  Yesterday Laurence received a late JT9 reception report from JH3XCU so the path does open at levels conducive to complete two-way contacts.  Select WSPR DX report details can be viewed here.
