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

Good daytime propagation reported as the evening session turns poor following unsettled geomagnetic levels in the afternoon; KK1W completes first reported JT9 QSO with NO3M; Special JT9 trans-Atlantic QSO opportunity by G0MRF beginning December 19!

Eastern North America sounded noisy last night as a large, active storm system was present in the Atlantic Ocean.  A few storms dotted Europe as was also the case for Japan.  The eastern population centers of Australia were clear while the Southwest of the continent and New Zealand were dealing with lightning-producing storms.  Hawaii was also reported as noisy by K9FD and KL7L/KH6.

Geomagnetic conditions reached unsettled levels during the afternoon in North America followed by quiet to elevated-quiet levels overnight as Earth moves across a coronal hole stream. The Bz is pointing slightly to the North this morning and solar wind velocities  are averaging near 430 km/s.  DST values are generally meandering near the centerline, mostly at negative levels.




Propagation seemed relatively poor and short range during the evening.  Trans-Atlantic openings were limited to the Northeast and were few in number.  This morning short hops were reported although a few weak, longer paths may have been present.  Daytime propagation was reported good but a few operators.

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.  David notes that this event will go through the New Year or until the antenna falls down.

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!):

Eric, NO3M, completed a JT9 QSO with KK1W, in Massachusetts, which happens to be Jim’s first reported QSO.

Al, K2BLA, reported that the “…Band sounds lousy only WSPR this AM hrd by 37 and hrd 11. Looks like low activity.

Ken, K5DNL, reported no JT9 QSO’s during this session but indicated that he heard KC3OL CQing this morning.  Using WSPR overnight, Ken reported sixteen stations including VE3EFF.  Ken was reported by 89 unique stations including ZF1EJ and seven Canadian stations.   Ken shared two-way WSPR reports with K9FD (/KH6) and VE3CIQ.

Neil, W0YSE, was briefly detected on CW this morning while calling CQ around 1100z but the opening was poor compared to the previous session.  Neil had the following comments and statistics for the session:

Robert, KR7O, reported that it was  “Pretty much a west coast night last night with only WSPR activity noted.  Did some transmit testing of the ~4W amp (no smoke).  Heard by 17 including several VE7s and best DX K9FD (-19) at almost 4000km with maybe 200mW ERP.  K5DNL, K4SV (21/-22) and K2BLA (-22) were the only NA stations copied beyond 2000km.

K9FD 72 spots, -4

VK4YB 3 spots, -21

Roger, VK4YB, reported a tough time this Summer down under while doing radio as noise and propagation seem much worse than previous years which seems to impact all activity, both domestic and international.  Roger indicated that “The Alberta twins usually hear me and report on PSK.” and adds that it may be March before two-way QSO’s will be possible again in Oceania.  Hopefully both ends of the trans-Pacific path will have some relief at some point.

The evening was uneventful on the air at KB5NJD.  The East was very noisy while the West was quiet.  K4EJQ was briefly loud on 473.75 kHz CW but it was obvious that QSB was present and paths were mostly short.  This morning I detected W0YSE calling CQ on 474.5 kHz CW but it was not as good as previous session so the band was a bit conflicted. I completed a CW sked with KF5RY and QRT’ed at 1100z.  I actually thought Steve was DX because I was listening to the West when he began calling.  I should be back tonight after dark.  Perhaps the band will be better tonight.

Finally, I am looking for a high level IRC user, administrator or expert.  If this is you, please let me know so we can talk.

Eden, ZF1EJ, reported thirteen WSPR stations including K9FD.

Laurence, KL7L, indicated that he heard and decoded K9FD as KL7L/KH6 while on the beach (reports not uploaded).  Noise was high due to ocean storms.  The station in Alaska remains off line following heavy weather.  Laurence will know more in the next 24-48 hours.

Merv, K9FD (/KH6), reported  eleven WSPR stations. He shared two-way reports with CF7MM, K2BLA, K5DNL, KR6LA, KR7O, N1VF, NU6O, VK4YB and W0YSE. Merv received reports from 36 unique stations including 7L1RLL4, JA1PKG, VK2XGJ, VK4YB, and ZF1EJ.  Storms near the island resulted in higher noise levels than previous session.
