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

Short hops and noise dominated domestic and some trans-Pacific paths but trans-Atlantic paths were very good; Another polar opening: KL7L -> LA2XPA; Solid openings KH6, KL7 -> JA; G0MRF QRV from remote site using WSPR to test performance. JT9 forthcoming!

The central US and gulf coast were the most active regions  for lightning in North America during this session.  Storms were also present in New England into southern Canada and the West coast.  Europe and Japan were mostly clear while storms are creeping North along the East coast of Australia.  K2BLA located in Florida reported that noise at the Winter Solstice was as loud as mid Summer.  This is not typical.

Geomagnetic conditions are at quiet to elevated-quiet levels.   The Bz is at unity this morning and solar wind velocities are averaging near 425 km/s.   DST values are variable but have generally remained near the centerline at negative levels.

 

 

 

Domestic propagation was reported to be very short range by many stations during this session.  Polar and trans-Atlantic openings were present, however.  Noise conditions depended on location but weather conditions appeared to have impacted a number of stations.

 

Reverse beacon network reports follow:

 

David, G0MRF, is active from his remote site about 200 miles away from his home QTH using an Icom 7300 and 114-foot tall antenna.  He operated WSPR last night to shake the system down, receiving and giving reports for a number of stations (detailed later in report).  David will be operating JT9 in hopes of completing trans-Atlantic QSO’s into 2018.

Alberto, EA4GHB, reported that he would be transmitting his Christmas message from 1900z – 2000z using QRSS3 on 474.6 kHz starting during this session and continuing for at least the next seven days.  The duration of the message is just over fifteen minutes long.

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!):

Ted, KC3OL, reported JT9 QSO’s with NC8W, KC4SIT and K2BLA.

Wayne, K9SLQ, completed a JT9 QSO with ZF1EJ.

Frank, W3LPL, provided analysis confirming that prime time to KH6 from his his stations over several previous sessions has been between 0700z and 0800z.  For this session, he added that “QRN was low tonight but propagation limited JT9 QSOs to single hop E-skip distance.   I was heard briefly by W7IUV.

Neil, W0YSE, reported that “Condx not so good this session from the PNW.  I made 2 JT9 Q’s last evening: Joe,NU6O (CA) and Clint, KA7OEI (UT).   On WSPR, I was heard by 34, including Laurence, KL7L. 

…and I heard only these 5: K9FD, KA7OEI, KL7L, KR6LA, NU6O.”

 

Roger, VK4YB, reported that “High static from storms in NSW and propagation is well down. Most of the signal is being lost between VK and Hawaii. Only one weak spot from JA3TVF and two from SWLCN74XP and a few from KL7L.

Robert, KR7O, reported “…lots of lightning static, only about four legal stations copied before 0600Z.  CDX that bad, or nobody transmitting?  Better after ~0530Z.  KL7L popped in after 1100Z.”
