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

Signals were weaker than normal and activity was spread out through the evening but many QSO’s were reported; K8RYU completes first reported CW QSO with K4EJQ. Long haul paths were down significantly; Portable JT9 operating activity by G0MRF beginning December 19!

North America was lightning-free during this session but snow static was reported by a number of operators in the East and Northeast.  Europe experienced many more lighting-rich storms during this session while the situation in Oceania was only moderately different with a few additional storms in the population centers of southeastern Australia.  Japan was generally free of lightning.  Pacific storms continue to result in noisy conditions for Hawaii.

Geomagnetic conditions were at quiet to elevated-quiet levels. The Bz is at unity this morning and solar wind velocities are averaging near 390 km/s.  DST values are riding the centerline with a trend toward positive levels.




Propagation appeared better earlier in the session but that may have been the result of differing activity levels during the evening.  Several stations reported that the daytime openings observed in previous sessions were not present during this one.  Noise was very low in many areas but snow static was reported by operators in the Northeast and parts of the Midwest.  Quite a few QSO’s were reported but the activity was spread through the evening rather than clumping into a few very active periods.  My guess is that spread band activity is how the band will function going forward so plan on tuning around and staying busy in between station activity.

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!):

Bunky, K4EJQ, completed a CW QSO with a new station on the band, K8RYU.  Ralph was heard around the band during the evening but its unclear what other stations he might have worked at this time.

Ken, K5DNL, completed a JT9 QSO with K2BLA.  Using WSPR overnight, he decoded 22 stations including VE3EFF.  He received reports from 92 unique stations including eight Canadian stations.  He shared two-way WSPR reports with ZF1EJ.  Ken was happy to see additional active stations during this session.

Phil, VE3CIQ, completed a JT9 QSO with WB4JWM.

John, AE5X, completed a JT9 QSO with ZF1EJ and K9SLQ and a CW QSO with KB5NJD.  An attempt was made with VE7SL on JT9 but John was not hearing Steve at the time of the attempt.

Neil, W0YSE, reported that he “…had 2 JT9 Q’s last evening, but it was a struggle to be heard. I called Keith, K0KE several times with no reply. Then I tried to get Clint’s attention, KA7OEI and finally got a response, and finished a QSO with him. Then later I tried Keith again and finally was heard, so we finished a QSO also.”  Neil added these statistics:

“As for WSPR, I was heard by 42 stations. Here are the ones over 3000 km, much better than the previous session. 

…including a couple of spots in the LOW 20’s. Not sure that has ever happened before. These WSPR results are so much better than the JT9 attempts earlier in the evening.

My reception of WSPR was not very good, however. I heard only these 9:

AE5X, K4SV (who was best dx for this session), and K5DNL, KA7OEI, KR6LA, KR7O, N1VF, NU6O, W7IUV”

Al, K2BLA, reported “…low noise good signals this AM wkd N1DAY last nite and K5DNL this AM on JT9. Too bad not more on this AM. WSPR hrd by 61 hrd 21…

Frank, W3LPL, reported that he completed JT9 QSO’s with KK1W, WB4JWM, KC3OL and W5EMC.  He also indicated that he received JT9 reception reports from VE6XH, VE6JY, VE7SL and W7IUV.

Matt, KA1R, reported that he completed JT9 QSO’s with WA1OJN and KK1W.

Terry, W8ARE, reported that he had no JT9 QSO’s last night in spite of hearing a few stations.  Using WSPR overnight, he reported twenty stations and received reports from 50 unique stations.  He shared two-way WSPR reports with ZF1EJ.   Not bad for a nineteen-foot-tall antenna on the patio of a condo!

Robert, KR7O, reported that “Activity seemed low last night.  Conditions were up and down based on my signal reports.  There was some JT9 activity from about 0530060Z with W5EMC, K9KFR and a couple of west coast stations copied.  W5EMC worked W3LPL, but no trace of LPL.  Heard by 16, including VE6JY (3/-24) and K9FD (13/-11).  Conditions seemed to improve after 0600z with 18 copied, including TC K4SV (46/-10), K2BLA (2/-18), W4BCX (6/-25), W3LPL (4/-24) and N1DAY (7/-23).

ZF1EJ 9 spots, -23 (best report in some time)

K9FD 13 spots, -7 (suspect Merv not transmitting overnight)

VK4YB 7 spots, -27″

Larry, W7IUV, received a reception report from W7HDL, located in Salmon, ID.  George heard Larry’s WSPR CW ID between 1430z and 1505z and also noting that it was “good and strong…” He added that he might have heard another very weak CW signal around that time as well as he was calling CQ on CW around 475 kHz.  George is working on his system at this time but reported to Larry that he has a “…WW-II Bendix TA-12 transmitter and receiving with a USN RBM receiver…

The band was quiet at KB5NJD during the evening but signals were relatively weak and QSB was active.  K8RYU was heard sending V’ early in the evening but I could not raise him following his test.  By the time he was working K4EJQ a bit later he was just a whisper in the noise.  K4EJQ went from S9 to nothing over the course of the evening as well.  I completed an interesting CW QSO with AE5X.  I suspect he had been calling for several minutes when I finally responded after switching directions on a whim.  John was strong, RST 579, here when listening on the proper antenna and we chatted a few minutes.  At one point his signal disappeared on the K9AY loop but was peaking on the resonant loop which was not hearing him at all a few moments earlier so the incoming angle changed significantly over just a few minutes.  NO3M reported me at RST 229 followed by RST 339 a bit later which is not typical.  I heard him calling CQ on 474.2 kHz some time later and found that QSB carried him into the noise.  Openings from my stations never really developed to any of the reverse beacon nodes in the Northeast but a few were reported in the Pacific Northwest.  The same was true this morning and the path to VE6 and VE7 seemed pretty good.  I completed a CW sked with KF5RY, followed by a few more CQ’s after 1200z before QRTing.  I will be off air tonight but will return in the morning for a CW sked and CQ session beginning at 1100z unless otherwise specified.

There were no trans-Atlantic reports during this session.
