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

Elevated geomagnetic conditions and solar wind result in “just OK” session with a few two-way QSO’s reported; Trans-Atlantic and Trans-Pacific openings favored higher latitudes but both paths were down significantly

The UTC amateur registration database is here.

HERE are a few mode-specific comments addressing where modes are located now and probably where they are best placed in the future

Noise conditions were similar to the previous session as North America was mostly lightning free.  A few storms were  present across Europe and northern Japan.  The eastern population centers of Australia were generally in the clear while the Southwest of the continent experienced strong coastal storms.  New Zealand was  storm free.

Geomagnetic conditions are at elevated-quiet levels as a coronal hole remains geoeffective with Earth.  Unsettled levels were anticipated but have not yet been observed.   The Bz is pointing to the North this morning and solar wind velocities are averaging near 440 km/s.  DST values are currently below the centerline at negative levels but are trending toward positive values this morning.




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.

Jim, W5EST, submitted the following WSJTx captures showing JT9 signals that were observed at his station in Little Rock, Arkansas:





The following stations provided reports of their two-way QSO’s as well as any additional activity that might have occurred during this session (this is not necessarily a complete list – only what was reported!):

Terry, W8ARE, completed JT9 QSO’s with K9MRI  and K9SLQ.

Ken, K5DNL, completed JT9 QSO’s with WB4JWM and K9SLQ.  Using WSPR overnight, Ken reported nineteen stations including VE3EFF.  Ken received reports from 103 stations including eleven Canadian stations.  He shared two-way WSPR reports with K9FD (/KH6) and VE3CIQ.

Neil, W0YSE, was likely heard at my station this morning  while calling CQ on CW which is the second or third time he has been reported here this season.  Neil submitted the following comments and statistics for the session:

Last evening I sent out some CQ’s on JT9. No takers, but PSKreporter showed at least 7 stations, all up and down the western states (BC to AZ), had decoded me. Then around 0250z i did some CW CQ’s on 474.74 kHz and was heard in Madera, CA by Robert, KR7O at 559 to 579 !!! Distance from there to Vancouver WA is 614 mi ( 989 km).

This morning I got on 474.5 around 1130z and Joseph, NU6O in N. CA could just barely hear a “CQ” but could not copy my call sign due to lots of static. 

As for WSPR…only 40 stations spotted my 2w EIRP this time. That’s down from recent sessions. Very few over 3000 km this time. Here are those over 2000 km distant:

…and I spotted only these 7: K5DNL, K9FD, KA7OEI, KR6LA, N1VF, NU6O, W7IUV

Robert, KR7O, reported  WSPR overnight, commenting that “Only the regular regional stations last night plus limited TC to the SE.  Only K4SV (25/-21) and K2BLA (-24) copied.

K9FD 96 spots, -2 (signals better in the evening than overnight)



KB5NJD was QRT during the evening but was active again this morning.  I called CQ for a few minutes beginning around 1100z ahead of a CW sked at 1130z and could hear someone calling at one point but never could resolve the signal or signal direction.  During my sked with KF5RY I heard a station lightly CQing in the background around 1130z.  Based on reverse beacon reports, it could have been W0YSE or K9SLQ but I am pretty certain it was W0YSE.  Due to some work in the ham shack I did not have the ability to switch to one of the more directional receive antennas during this session in an attempt to resolve the signal, instead I was using the rotatable bi-directional loop so the signal could have been from anyone.  This project will be completed by the evening session.  I QRT’ed at 1200z.

Eden, ZF1EJ, reported thirteen WSPR stations including K9FD.

Laurence, KL7L, was apparently off air back in Alaska.  He continues to report K9FD while on assignment in Hawaii, listening as KL7L/KH6.


Merv, K9FD (/KH6), reported nine WSPR stations. He shared two-way reports with K4SV, K5DNL, KR6LA, N1VF, NU6O, VK4YB, W0YSE and W7IUV. Merv received reports from 42 unique stations including 7L1RLL4, JA1PKG, JA3TVF, VK2XGJ, VK4YB and ZF1EJ.
