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

Slow start gave way to a very strong night as quiet geomagnetic conditions continue and DST values spike to highest levels in some time; Many JT9 QSO’s completed including one transcontinental QSO between W3LPL and W7IUV; N1BUG’s new WSPR setup does well with trans-Atlantic reports from EA8BFK and PA0O; New CW station in Colorado, W0PXM, worked by KD0VBR

The band was quiet in North America for the most part although a few storms were present overnight and in the morning in parts of the upper Midwest into New England.  The line of storms recently impacting parts of the southeastern US is now ranging from Central America towards the North Atlantic.  Northern Europe is experiencing spotty lightning-rich storms as are parts of southern Europe.  Japan is once again inundated with lightning this morning as are parts of eastern and western Australia.

Geomagnetic conditions were very quiet. The Bz is pointing slightly to the South this morning and solar wind velocities are averaging near 400 km/s, just under moderate limits.  DST values are very encouraging with both measurements at or above the centerline.




Propagation was slow to develop but blossomed by late evening as noise levels dropped and the band stabilized.  A number of operators reported activity in the 10-meter contest so some were “fashionably late to the party” while others were active in an antique wireless association memorial event.  The band was quiet this morning and based on reports, propagation was pretty good.

Reverse beacon network reports follow:


Nicolas, F4DLT, reported “TM77T special call for the annual mobilization “Telethon” in France.  QRSS3 QSO today : 20H30 GMT 476,200 khz  https://evenement.telethon.fr/2017/

David, G0MRF, reported an upcoming remote operating activity 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 follow screen captures of his WSJTx console showing JT9 QSO’s received 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!):

Dave, AA1A, was heard completing a CW QSO with Bunky, K4EJQ.

Rob, NC0B, reported hearing a CW QSO between Tom, KD0VBR, and Mark, W0PXM, both of Golden, Colorado.  Rob indicated that Tom was using a BC375 transmitter which had a bit of chirp and also submitted this video showing operation.  It is good to know Tom was QRV as I’ve not heard him since opening weekend.  Using JT9, Rob completed JT9 QSO’s with W8RUT, KA9OKH, NC8W, KC3OL and W3LPL.

Terry, W8ARE, completed JT9 QSO’s with K2BLA, W3LPL, N9RU, NC8W, K5DNL and W8RUT.  He also reported this morning that he decoded VK4YB’s WSPR signal:

Ken, W8RUT, reported elevated noise at his QTH by two or three s-units and wonders if the source could be Christmas lights.  Ken completed seven JT9 QSO’s during the session including K5DNL, AA1A, VE3CIQ, W8ARE, NC0B, WB4JWM and KC3OL.  Using WSPR, Ken reported that over the previous 12-hours he was “…Heard by 81 unique (Best K9FD -17) , Hearing unique 21 (Best K9FD).

Frank, W3LPL, reported his first transcontinental JT9 QSO with W7IUV.  Frank noted that KR7O and VE7SL were also decoding his JT9 signal around the same time.  He also completed a JT9 QSO with newcomer NC8W.   Frank added that he had transcontinental WSPR reports from CF7MM,   KPH,   KJ6KO,   KK6EW,  KR6LA and  KR7O during this session.

John, WA3ETD, report a JT9 QSO with K5DNL at 1000z.  John added that “W0YSE Neil was spotted here on WSPR for the 1sttime this season.  Conditions improving! I was contacted by Mike N1JEZ for some testing.  He was at his camp and was spotted on WSPR but an attempt at JT9 was unsuccessful.  At this time I have no details regarding his lashup.

Roger, VE7VV, reported “JT9 QSO’s with KA7OEI (first with Clint and first UT), K5DNL and NU6O.

Al, K2BLA, reported that he “Worked 4 JT9 “regulars” and one new one, NC8W. Operated a little bit of WSPR and was heard by 56 and heard 18.

Ken, K5DNL, reported a big night, completing JT9 QSO’s with W8ARE, NC8W, W0YSE, WA3ETD, K2BLA and VE7VV.  Using WSPR overnight, Ken reported 23 stations including VK4YB and he received reports from 93 unique stations including ZF1EJ and nine Canadian stations.  He shared two-way WSPR reports with K9FD (/KH6) and VE3CIQ.

Keith, K0KE, reported JT9 CQ’s from VK4YB this morning:

Neil, W0YSE, had a hard time getting out of bed this morning but noted a lot of JT9 activity on his receive console  He posted this receive transcript on the 600-meter research group email reflector.    Using WSPR overnight, Neil indicated that his results “…were probably the best this season with 54 stations decoding me. Here are the most distant ones…

…and I decoded 10, including Roger, VK4YB three times (best of -28). Here are the most distant…

Early mornings seem to give the best chance for me to make Q’s, but it is so hard to get myself out of bed so early.”


Robert, KR7O, reported “Frequent lightning crashes, but they did not appear to have any impact on reception.  Good conditions and quite a bit of JT9 activity last night, including K2BLA in early at 0134Z, W8RUT, K9MRI and the regular regional stations with several QSOs noted Nice conditions overnight on WSPR to the Great Lakes area with W8RUT (21/-17), WD8DAS (3/-26) and first time receptions of NC8W (1/-26), VE3CIQ (1/-28), KA9OKH (1/-29).  TC to K4SV (62/-17), K2BLA (-20) and W3LPL (15/-23).

K9FD 72 spots, -7 (KH6 path still depressed a little bit)

VK4FD 33 spots, -17 (0958-1402Z)  Great VK path this morning including several JT9 decodes from 1316-1334Z)


It was reported yesterday that Paul, N1BUG, was testing his new and very beautiful homebrew variometer.  I may be incorrect but I believe that he was on the air with the U3S and a small amplifier at 22 watts TPO for about 2 watts EIRP.  Paul had trans-Atlantic WSPR reports from EA8BFK and PA0O.  Congrats Paul!

Ken, SWL/K9, in Indiana, reported:

It was a slow evening at KB5NJD.  I wasn’t on the air long and missed the late evening flurry of activity when the band was really significantly better.  I heard K4EJQ in a CW QSO with AA1A and briefly heard Dave for what may have been the first time on CW.  It was detection only but perhaps later in the evening he would have been workable here.  If I recall correctly Bunky was sent him RST 339 so not too hopeful 700 mile further to the West.

This morning the band sounded good but the late night kept everyone in bed it seems.  I called CQ through sunrise, receiving a number of reports  on RBN from VE6WZ even after first light.  I continued to call in hopes of a sunrise report but it was not going to happen this time.  I was surprised to have the late report at 1304z.  I received two reports via email during this session including RST 599 from Mike, W0MB, located in Independence, Missouri,  at 0149z. He indicates that he is not ready to transmit yet.  I also heard from Bruce, N9BH, located in Niangua, Missouri, who reported that I was heard at 1212z while he was operating WSPR.  Thanks for the reports guys.  I look forward to a QSO soon!

Laurence, KL7L, continues to report K9FD while on assignment in KH6 as KL7L/KH6.  Back in Alaska Laurence reported seven WSPR stations including VK4YB and K9FD.  He remains in a receive-only capacity due to a likely fuse problem with the transmitter back in Alaska.

Merv, K9FD (/KH6), reported fifteen WSPR stations. He shared two-way reports with VK4YB, K4SV, K5DNL, KC3OL, KR6LA, NU6O, VE3CIQ, W0YSE, W7IUV and W8RUT. Merv received reports from 55 unique stations including 7L1RLL4, JA1PKG, JA3TVF, KL7L, VK2XGJ, VK3ALZ, VK4YB, VK7TW and ZF1EJ.
