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

Activity was down a bit in observance of Christmas but transcontinental and trans-Atlantic paths remain strong in spite of QSB; Late polar reports of KL7L at LA2XPA; Hellschreiber message from Santa; Fessenden Christmas transmission by WI2XLQ using Heising modulation

It was a bit noisy at times during the evening in North America as storms were concentrated out at seas along the Atlantic coast.  A few storms were present from the Midwest into parts of New England and a a few storms present South and West of Mexico likely impacted West coast stations if history repeats itself.  A few storms were present in parts of western Europe along the Atlantic coast while fewer active lighting-rich storms were present over Japan compared to recent sessions.  Oceania continues to experience strong storms driven by high Summer heat.  Noise was reported to be very high in Australia by VK4YB and VK2XGJ.

11-hour worldwide lightning summary

 

Geomagnetic conditions continue at elevated-quiet levels as the Earth moves through a solar wind stream from a geoeffective coronal hole according to Solarham. The Bz is pointing slightly to the South this morning and solar wind velocities are averaging near 540 km/s. DST values have decreased but remain near the center line.  Unsettled conditions are possible through the next 24-48 hours.

 

 

 

Propagation was OK but subject to high QSB and lighter activity in observance of Christmas activities.  The polar path from KL7 was open late to Scandinavia.

Reverse beacon network reports follow:

 

John, WA3ETD, reported the presence of Santa just above the WSPR passband, spreading cheer on 630 meters with this transmission:

Other Hellschreiber transmissions were reported but at this time no details have been received.

Brian, WA1ZMS, reported the transmission of his Christmas “Fessenden” / Heising modulation transmission and supplied these comments:

“Like in years past, WI2XLQ is now on-air on 486kHz full carrier AM for the annual transmission. Same 5 min audio loop as always. The exciter is the 1921 Heising MOPA and the amp is the SSPA Hafler 9505. 200w carrier out of the amp into the T-antenna. Will be QRV for at least 24 hrs.”

Eric, NO3M, posted this recording on his website.  Brian was reported as far West as K9FD in Hawaii.

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

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!):

Al, K2BLA, indicated that he completed JT9 QSO’s with “…AA1A and VE3CIQ this AM on JT9. WSPR heard by 53, ten over 2000 km. Heard 22 including K9FD.”

Tom, WB4JWM, completed a tough JT9 QSO with KC3OL that was plagued with QSB during the evening.

Ted, KC3OL, completed JT9 QSO’s with K0KE, K8TV, and WB4JWM.

Dave, AA1A, reported JT9 QSO’s with K2BLA and K8TV.

Ken, K5DNL, reported 21 WSPR stations and he received reports from 85 unique stations including KL7L, K9FD (/KH6), ZF1EJ and twelve Canadian stations.

Robert, KR7O, noted transcontinental openings and improvements for his station:

“Tested new ATU and scopematch last night at 4.2W TPO.  Heard by 34 including my first positive signal reports and first receptions east of the  Mississippi.  Best continental DX, N4WLO (AL) and W0DJK (MN).  Also copied by three different VE6’s, which I almost never reached before.  K9FD reported signals up to -12.  First reports from NB9E in NV, hopefully he will be making contacts.  Looks like a solid improvement in efficiency compared to the original, small coil.

On reception, activity was obviously low.  The evening started out with quiet conditions, but lightning crashes were strong mid-evening until at least 0700Z, but subsided sometime overnight.  Heard 19 on WSPR including W5OXC (1st time), W8RUT (17/-17), K4SV (39/-11), K2BLA (3/-19), W4BCX (2,-24) and W1IR (9/-22).

ZF1EJ – 7 spots, -26
K9FD – 99 spots, -4
KL7L – 57 spots, -14
