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

Typical Operating Schedule

Usually QRV CW most evenings, tuning between 472.5 kHz and 475 kHz with CQ's on or near 474.5 kHz. Occasionally QRV JT9, 474.2 kHz dial + 1000 - 1350 Hz. QRV some mornings starting around 1100z on CW. Sked requests are welcome. All activity is noise and WX permitting

Poor session in spite of relatively normal band activity as unsettled to G1 storm conditions continue; Uncharacteristically noisy for a December night in North America; G0MRF portable operation begins on December 19 with a focus on JT9 for North America

It was noisy in North America due to a storm system ranging from the Pacific coast of Mexico across to the Gulf coast.  The Mediterranean and southern Europe remains stormy and a few storms are active this morning in parts of northern Japan.  In Oceania, the northeastern population centers are clear but continue to be impacted by storms to the south and south central regions of the of the continent.  VK4YB reported continued high noise but enough of a relief to hear Hawaii during this session.

Geomagnetic conditions remain at unsettled to storm levels due to a geoeffective coronal hole according to Solarham. The Bz is pointing slightly to the South this morning and solar wind velocities are averaging near 600 km/s.  DST values remain at negative levels with a few rapid, deep decreases observed.  The A index is currently 24.

 

 

 

Propagation was weak and impacted by QSB but there were a few bright spots on shorter hops across North America.  Noise was high for December and elevated A indices suggested that absorption was high, particularly for the poor souls at higher latitudes.  Most signals were down during this session making it a tough night that is uncharacteristic for this time of year.

Reverse beacon network reports follow:

 

David, G0MRF, reported an upcoming remote operating activity starting on December 19 that may give North American stations a very good chance to work him using JT9.  David will be using an Icom 7300, amplifier and filtered preamp from a very quiet site that he has used in the past.  The antenna will be 114-foot tall and located at a high location if I am recalling correctly.  Mark your calendars as David is planning on losing sleep to make this event a success.  More details will be forthcoming as the date nears.  David notes that this event will go through the New Year or until the antenna falls down.

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!):

Terry, W8ARE, reported a JT9 QSO with K9SLQ this morning,  He also observed JT9 activity from KB5NJD, AE5X and ZF1EJ “…But conditions just not quite good enough for me to get a signal back to you all.

Wayne, K9SLQ, was a hot commodity during this session, completing JT9 QSO’s with K2BLA, K8TV, NC8W, WB4JWM, W8ARE, and ZF1EJ.  This morning Wayne completed a CW QSO with KB5NJD.

Wayde, K3MF, continues to test his transverter, completing a CW QSO with K1RGO during the early evening.

 Tom, WB4JWM, completed JT9 QSO’s with K5DNL and K9SLQ.  He called me on JT9 and I answered him but botched one of the transmission cycles so no QSO.  Since we have a number of JT9 QSO’s in the past, we left it at that, acknowledging QSB and weaker signals in the MF/LF chat.

Ken, K5DNL, reported a JT9 QSO with WB4JWM.  Using WSPR overnight, he reported 26 stations which is a new record for Ken and an indicator that transmit activity is increasing.  Ken received reports from 88 unique station including K9FD (/KH6), ZF1EJ  and nine Canadian stations.  He received forty WSPR decodes from YV7MAE.

Roger, VK4YB, reported the “Usual storms here but it just relented sufficiently to get a decode of Merv. No good for 2 way stuff though.

Neil, W0YSE, reported a tough night for propagation and noise at his QTH:

“Pretty poor night from Vancouver WA this session. I was heard by 36 WSPR stations, and got to W. PA and Hawaii and S. TX, so coverage was not too bad. Here is my DX for this session.

…and I heard these 9 WSPR stations: AE5X, AH6EZ, K5DNL, K9FD, KA7OEI, KL7L, KR6LA, N1VF, NU6O

I discovered that my “neighborly QRN” (which comes on intermittently year around) spans from 465-476.5 kHz and it is absent from 477 and up. So I might be using the upper 2 kHz for scheduled QSO’s on CW at least, and maybe some other modes. My ANC-4 noise canceler usually takes care of most of it, but not always.”

Robert, KR7O, reported that the band was OK at his QTH:

Conditions not bad despite ugly ST numbers, but very low activity.  Only VE7VV and N1VF on JT9 last night and copied K9SLQ working K2BLA from 1029-1058Z.  17 spots on WSPR including TC WD8DAS (-29), K4SV (52/-18), K4LY (8/-23) and ZF1EJ.

ZF1EJ 7 spots, -25

KL7L 36 spots, -18 (surprising)

K9FD 109 spots, -2 (signals improved after 0700, but pretty much normal CDX).

VK4YB 1 spot, -27

 

Larry, W7IUV, reported JT9 from VK4YB this morning:

1156 -26  0.2 1098 @  DE VK4YB QG62  

1212 -27  0.0 1098 @  DE VK4YB QG62  

1218 -27 -0.1 1098 @  DE VK4YB QG62″

 

It was a  noisy evening at KB5NJD.  I had weak detection of K3MF during a brief, early CQ session on CW.  Wayde was gone by the time I returned from dinner but the band was deteriorating as the evening progressed.  K9SLQ responded to my CQ on CW this morning with a strong signal.  We exchanged RST 579 reports and went on our way.  I had no CW sked this morning and QRT’ed earlier than normal to get the day started.  Late this morning I received an email from Alan, KB5CUS, located about 30 miles away who reported hearing my CQ’s on CW last night at S9+ using a 75-meter dipole.  I am working to convince Alan to get on the air as he, like so many others, has incorrect preconceived notions about what is necessary to get on the air.  I referenced the exhibits that were presented in the last few days by W8ARE who is using an 19-foot-tall vertical on the patio of his condo.

Eden, ZF1EJ, completed a JT9 QSO with K9SLQ and was reported to be CQing at times through the evening.  Using WSPR overnight, Eden reported fifteen WSPR stations  and he received reports from 59 unique stations.  He shared two-way reports with K9FD.

Aaron, AL4Y, reported WSPR signals for what may have been the first time on 630 meters, including  reports for AH6EZ, K9FD, KL7L, KR6LA and W0YSE.

Laurence, KL7L, operated a bit of JT9, receiving a report of a trace of his signal from N1VF, who was also calling CQ on JT9 at the time.  Ben indicated that the signal, which was presumed to be Laurence, did not decode.  Overnight Laurence reported three WSPR stations including VK4YB and he received reports from twelve unique stations including JA1PKG. He shared two-way reports with K9FD and W0YSE.  This morning Laurence reported that he observed a “Blue Green weak Au glow to North 15deg above horizon at 10Z but nothing I can see now – temps dropped to 10F, so MF tuning just about dead on.  K peaked 5 here around 9Z but quietening down…overall depressed a bit but not awful yet… unimpressive iono above me – https://lgdc.uml.edu/common/ShowIonogramPage?mid=27667829&ursiCode=GA762&time=2017.12.18%20(352)%2014:45:10.000

Merv, K9FD (/KH6), reported high evening noise and low expectations for the session.  He managed to report fifteen WSPR stations overnight, sharing two-way reports with AE5X, AH6EZ, K4LY, K4SV, K5DNL, KR6LA, N1VF, NU6O, VK4YB, W0YSE, W7IUV and KL7L.  Merv received reports from 63 unique stations including 7L1RLL4, JA1NQI/2, JA1PKG, JA3TVF, JE1JDL, JH3XCU, TNUKJPM.
