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

Historic JT9 QSO completed between AA1A and G0MRF as trans-Atlantic propagation continues to offer nice surprises; Polar path between KL7L, W7IUV to LA2XPA continues while others in the East also enjoy these high latitude openings to Scandinavia; Many good, late transcontinental openings but probably not as robust as previous session; K1UTI first reported JT9 QSO with K2BLA

Storms continue in the south central US into the Southeast during the evening and overnight.  Central Japan continues to be a focal point for lightning-rich storms while southern Australia continues to experience storms that are generating noise all along the East coast of the continent.

Geomagnetic conditions began very quiet only to end at elevated-quiet levels ahead of forecast unsettled conditions according to Solarham. The Bz is pointing to the South this morning and solar wind velocities  are averaging near 345 km/s. DST values look very good and remain at positive levels but expect these values to decrease at the onset of unsettled conditions.

 

 

 

Propagation was pretty good although activity was a bit light ahead of the Christmas holiday weekend.  A number of transcontinental openings were reported in addition to trans-Atlantic openings that led to one historic QSO during this session.  Polar openings from the Pacific region continue while trans-Pacific openings were 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!):

Dave, AA1A, and David, G0MRF, completed a historic two-way JT9 QSO which is believed at this time to be the first of its kind on this trans-Atlantic path operating under amateur radio rules.  Dave, AA1A, submitted the following text transcript:

Following acknowledgements from both stations, AA1A requested a CW QSO but G0MRF had to decline as he is operating remotely which complicates the process.  At receive levels into the mid -20’s I have serious doubts that a CW QSO would have been possible without a very significant and fortuitous peak.  David’s activity will continue through the new year beginning around 0000z for North America.

Neil, W0YSE, reported good success at reduced power and offered the following statistics and comments:

“My power supply issue is temporarily resolved. My old home-brew PSU 22 volt supply has been spewing spurs +/- 120 hz (and maybe more) that have been polluting the band near my signal. No amount of filtering would tame it. So I have had to opt for my Radio Shack 13v back up PSU, which puts my EIRP down to ~1w.

In spite of the lower power, last evening I had an easy JT9 Q with Rob, NC0B in Colorado (S,R: -6, -15). Rob is running a Monitor Sensors transverter at 50w TPO which seems to be doing very well for him.

My JT9 screen this morning shows these stations were active overnight: VE7SL, CF7MM, KA7OEI (UT), N1VF (ca), NO3M (W.PA), VE7VV, and KL7L (AK).

As for WSPR, my 1w EIRP WSPR was decoded at 33 stations. I got into AK to KL7L nine times with a best of -18, and out east to NO3M eight times (best -25), and to K9FD (KH6) 20 times (best = -18). Here are those most distant:

…and heard these 8 WSPR stations: K1YQP, K5DNL, K9FD, KA7OEI, KL7L, KR6LA, N1VF, W7IUV.

Thanks to those who submitted suggestions as to how to tame my old PSU. I may be trying those out after the holidays.”

John, WA3ETD, reported a JT9 QSO with N9RU, which was a new station for John,  and also  he observed K8TV for the first time operating JT9.

Al, K2BLA, reported that he “Worked two new ones on JT-9; K1UTI and K8TV. Worked WA3ETD just for fun. Saw NC0B calling VK4YB and could see a weak trace on the “other” sequence but no decode. I watched for a while in great anticipation but nothing came of it. On WSPR heard by 55 and heard 22 including G8HUH and two-ways with K9FD. Quiet last night but moderate noise this AM.

Bob, K9KFR, completed JT9 QSO’s with VA7MM and K5DNL.

Tom, WB4JWM, completed JT9 QSO’s with K9SLQ and KC3OL.

Rob, NC0B, submitted the following detailed comments and statistics for the session:

“Not much happened tonight except working the regulars.  I’ll attach my log at the bottom of this e-mail.  WA1OJN decoded me at -14 and we e-mailed back and forth, but I never saw a peep out of Bob.  A QSO with N0GMT never completed as to me copying a signal report, though I kept trying.  AA1A and N03M were calling G0MFR to no apparent avail.  Two stations I would have liked to have worked never called CQ.  W3ETD and K8TV.  Saw N1VF call N03M once, but nothing came of it.  QRN got worse over the night.”

Rob completed evening JT9 QSO’s with CF7MM, W0YSE, KC3OL, VE7VV and WB4JWM.  He added that he “decoded VK4YB twice this morning, 1116Z @ -26 and 1126Z @ -27…” and completed a JT9 QSO with K8TV this morning.

Larry, W7IUV, reported that there was “Little to report, no JT9, WSPR overnite gave usual suspects, including VK4YB, LA2XPA, ZF1EJ, KL7L, and lots of other NA stations.

Roger,  VK4YB, reported that the “Session started very promising with a decode of Merv 20min before sunset. Nice early peak but now it has collapsed in a heap.

Robert, KR7O, reported a number of transcontinental openings and offered these comments and statistics:

Still some lightning crashes, but noise down overall.  Good JT9 activity with 10 including NO3M, K9KFR and KL7L.  Also copied NC0B calling VK4YB from 1121-1135Z.  21 copied on WSPR including K4SV (38/-14), W3LPL (-27), KC4SIT (29/-16), W4BCX (21, -21), W8RUT (18/-20), K2BLA (-21) and ZF1EJ.

ZF1EJ 5 spots, -25

KL7L – 39 spots, -16

K9FD 87 spots, -8

VK4YB 6 spots, -23

John, VK2XGJ, reported very early openings to K9FD (/KH6):
