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

Decent session for western portions of North America but the East remains ‘blah’ as Gulf noise complicates some weak signal operating; Trans-Atlantic openings favor higher latitudes in Europe likely due to noise in the South; Standard fare for the Pacific

The Gulf of Mexico was a hotbed for noise in and around North America.  A few storms were also reported in the Midwest and off of the coast of southern California.  Southern Europe and the Mediterranean remain active, possibly explaining why many trans-Atlantic reports were limited to northern Europe.  Japan was once again an active recipient of strong storms in many population center as was the case to the South in Oceania.

Geomagnetic conditions reached unsettled levels.  The Bz is pointing to the South this morning and solar wind velocities are averaging near 490 km/s. DST values have decreased from highs but generally remain at or near the centerline.




Evening domestic propagation was weak and QSB was again prominent.  Eastern paths improved modestly by late evening. Trans-Atlantic openings seemed to favor higher latitudes which may have been a function of noise in southern Europe.

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!):

Neil, W0YSE, reported a JT9 QSO with VA7MM.  Neil added that he

“…also saw Laurence, KL7L calling CQ on JT9. I called him several times but no answer. Laurence’s signal was between -27 and -23, and I was probably 5 or 6 dB weaker in his direction. I even cranked my power up to over 2.5 watts EIRP to see if I could bust thru the ether, but feared for my final FET for that whole minute !!

My JT9 screen this morning shows that I also decoded the following this session: VE7CNF, NU6O, KR7O, N6PIG, and NO3M (-26 TO -23). 

As for WSPR, I heard these WSPR stations: K5DNL, K9FD, KA7OEI, KL7L, KR6LA, KR7O, NU6O, VA7MM and I was heard BY 38 stations…”  Neil submitted the following statistics and data for his WSPR activity:

Wayde, K3MF, reported a daytime CW QSO with Mike, W3TS, located about 50 miles to his North.  Wayde indicated that Mike was RST 459 and using  15 watts to a 200-foot long wire.  Wayde also completed a JT9 QSO with KB5NJD.  Second hand reports suggest that JT9 QSO’s were completed with W9XA and KC3OL.

Toby, VE7CNF, was observed in a JT9 QSO with NU6O during the early evening.  All indications are that the QSO was completed.

Ken, K5DNL, indicated that he operated WSPR through this session, reporting twenty stations and receiving reports from eighty unique stations including KL7L, K9FD (/KH6) and eleven Canadian stations.

Robert, KR7O, reported “Reasonably quiet conditions, but mostly fair propagation.  Primarily another west coast event, but there were some short waves of TC.  On JT9 copied N9RU, NO3M, W9XA, KL7L and one sequence of VK4YB.  On WSPR, I was copied by 18, but none exceeding 2000km during limited tests Only copied 15, including WD8DAS (4/-23), W9XA (2/-21), W3LPL (6/-25), W1IR (10/-22), WA3ETD (-29) and ZF1EJ.  Only one TC decode after 0700Z and none after 0728Z.

ZF1EJ 7 spots, -26

KL7L 18 spots, -18

K9FD 111 spots, -6

VK4YB 2 spots, -28

This was a noisy session at KB5NJD.  Signals were mostly weak and a few signals that are normally very strong exhibited strong QSB that appeared to be pretty fast.  I was seeing JT9 decodes of VE7CNF as he worked NU6O but subsequent calls to Toby following their QSO did not result in m own QSO.  I was fortunate to work K3MF during the evening using JT9.   Wayde indicated that he was not seeing my CW from just a bit earlier.  K4EJQ was uncharacteristically strong on CW here during the evening.  Reverse beacon network reports were received by late evening with two reports at surprisingly high levels.  This morning I had a sked with KF5RY at 1130z as I try to readjust to morning activity following the holidays.  W3TS was calling CQ this morning but he was not heard here in North Texas.  I was detecting a CW signal on or near 474.5 kHz following my sked but there were never any reverse beacon reports to account for it so it could be my ears playing tricks or seasonal mixing products.

Eden, ZF1EJ, completed a JT9 QSO with NO3M according to a second-hand report from W5EST.  Using WSPR, Eden reported fourteen WSPR stations and he received reports from 54 unique stations including LA2XPA.  He shared two-way WSPR reports with K9FD.

ZF1EJ session WSPR summary


Laurence, KL7L, reported seven WSPR stations including VK4YB and he received reports from nine unique stations. He shared two-way reports with K9FD, KR6LA and NU6O.  Laurence transitioned to receive-only at 0711z due to high winds.  Snow static was a problem at times.

Merv, K9FD (/KH6), reported nine WSPR stations including VK4YB. He shared two-way reports with K5DNL, KA7OEI, KR6LA, NU6O, VA7MM, W0YSE and ZF1EJ. Merv received reports from 38 unique stations including JA1PKG, JE1JDL and JH3XCU.
