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

Very good propagation as DST values push to high positive levels although unsettled conditions are returning; AB5S takes maiden voyage on CW completing a quick QSO; Another good night for stations in New England on path to KH6; Coming portable JT9 operating event by G0MRF; 9Q6BB listening to WSPR from Democratic Republic of Congo

North America was mostly lightning free aside from a few storms in the upper Midwest into New England.  Southwestern Europe experienced active, noisy storms and the western Pacific continues on a roller coaster ride as Japan and Australia are dotted with storms.

Geomagnetic conditions are at quiet to elevated-quiet levels ahead of forecast unsettled conditions. The Bz is pointing to the South this morning and solar wind velocities are averaging near 390 km/s. DST values have enjoyed nice peaks at positive levels but the trend this morning is down, approaching the centerline into negative levels.




Propagation was really very good and the extent was really obvious by mid evening when more stations were active.  Noise remains very low.  The good propagation continued this morning in spite of the slightly more active geomagnetic conditions.

Reverse beacon network reports for the session follow:


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.

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, AB5S, completed a short CW QSO with me, KB5NJD, during the evening.  Dave indicated that he was using his “WWII BC-375 transmitter and BC-348 receiver, ‘B-17 Bomber Station.’” and was keying with the transmitter test button as he was not planning on me being there when he turned the rig on.  He is using loading his 80-meter delta loop, fed against station ground (like a top loaded vertical where the feeder is the real radiator and the loop is the top load).  Welcome aboard, Dave!

Neil, W0YSE, reported “Not much happening this morning. I looked at 1100z and everyone must have been sleeping so I went back to bed. Got up around 1325z and put out a few JT9 CQs but Nil…Last night I had JT9 Q’s with Roger, VE7VV and Steve, VE7SL and Ben, N1VF.”  Neil was also heard on CW at my station while he was calling CQ briefly on 474.5 kHz but was not hearing my calls.  Neil added that:

“WSPR gave me good results this session. I was heard by 51 stations including Eden, ZF1EJ, and Laurence, KL7L. Here are those over 3000 km…

I heard 9, including these 3 from Roger, VK4YB. This was using my TX vertical for RX as well…

The other stations I heard were K4SV, K5DNL, K9FD, KC3OL, KR6LA,  and N1VF.

Al, K2BLA, reported that he “Worked 3 “regulars” this AM on JT9 with good signals; W8ARE, KA9OKH, K9SLQ. Didn’t see any “DX”. WSPR last nite and this AM: Hrd by 64 and Hrd 21.”

Terry, W8ARE, completed JT9 QSO’s with N9RU, K2BLA and W3XY.  Terry indicates that W3XY was a new station for him and added that he uploaded 630-meter QSO’s to LoTW and eQSL yesterday.

Robert, KR7O, reported “Another repeat to the Great Lakes, but not as good as the previous session, with K9KFR, K9MRI and W9XA and NO3M on JT9 copied.  NC8W (4/-23), VE3CIQ (4/-24) and TC K2BLA (2/-19), K4SV (52/-14), W3LPL (6/-23) were copied on WSPR.  I think NC8W was a first time reception.

K9FD 81/-5

VK4YB 15 spots, -25

This was a very good session at KB5NJD.  During the mid evening I heard a few stations calling that I simply could not dig out of the noise in the East and Northeast but the West and Northwest seemed to dominate the session due to a CW QSO with VE7SL.  Steve started out as very good copy but after we exchanged reports QSB began to set in.  I’m pretty sure Steve conveyed something else that I missed or he asked a question but as the fade was progressing I sent 73 and we moved on.  A bit later I heard W0YSE calling CQ on 474.5 kHz CW but he was not hearing me.  Its great to hear Neil making the long trip from Vancouver, Washington.  I also completed a local QSO with AB5S about 50 miles to the Northeast.  Dave sounded good with a hint of power supply sag on his signal.  Thanks for the call Dave!  As I was shutting down the station after being out of the shack for a bit, I heard W0PXM calling CQ near 474.5 kHz on CW so I responded and made a quick QSO with Mark, who is located in Golden, Colorado.  Mark appears to have joined us for the first time this weekend as Rob, NC0B, heard him in a QSO with KD0VBR in the previous session.  Mark has a good, stable signal and I look forward to working him again.  That was a good way to end the night.  This morning I made a few calls on 474.5 kHz CW prior to an 1130z sked with KF5RY.  Steve is learning to use a “cootie” key so he is using morning skeds with me on 630 meters for his practice session.  He sounds pretty good.  I QRT’ed at 1200z to get the day going.  I will be QRT tonight but will return tomorrow morning around 1100z for more radio action.

Hideo, JH3XCU, submitted this link detailing DX -> JA WSPR decode totals and DX -> JA WSPR S/N peaks for the session, as reported on the Japanese language 472 kHz website.


One station reminds us that the power reporting convention for MF and LF is estimated EIRP and not total power out.  Because antennas vary so much, its impossible to really translate what 20-watts TPO really represents.  Its hard enough translating radiated power accurately!

Laurence, KL7L, continues to report K9FD while on assignment in Hawaii as K9FD/KH6.  His receiver in Alaska reported four  WSPR stations including VK4YB and K9FD.


Merv, K9FD (/KH6), reported thirteen WSPR stations. He shared two-way reports with K2BLA, K4SV, K5DNL, KR6LA, N1VF, VE3CIQ, VK4YB, W0YSE, W3LPL and W7IUV. Merv received reports from 54 unique stations including 7L1RLL4, JA1PKG, JA3TVF, JE1JDL, KL7L, TNUKJPM, VK2XGJ, VK4YB and ZF1EJ.
