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

Lower activity than previous session but many QSO’s reported including 30 mW TPO JT9 QSO’s at W0SD with K9KFR and NO3M; Quiet geomagnetic conditions return but extremely high noise in parts of Europe and the Pacific Rim; WSPRnet outage impacted many reports

North America was generally quiet in spite of a few storms in the middle of the Atlantic.  The Mediterranean is active this morning as is central Japan.  The big story is Oceania, which is experiencing lightning from the southeast coast of Australia, North  through many population centers and West along the northern coast.  VK4YB confirmed that it was very noisy in Queensland.  New Zealand was also impacted on both the North and South Island.

Geomagnetic conditions have returned to quiet levels.   The Bz is pointing to the South this morning and solar wind velocities  are averaging near 425 km/s. DST values have returned to the centerline and are maintaining good stability.




Activity was down during this session, presumably due to a New Years Eve hangover for many but the band was open, producing many transcontinental QSO’s.  WSPRnet was down for a significant portion of the overnight and morning so there is limited data for a number of paths.  All WSPR data should be considered incomplete.

Reverse beacon network reports follow:


Jim, W5EST, submitted the following screen capture of his WSJTx console showing JT9 activity observed at his station in Little Rock, Arkansas:

Roelof, PA0RDT, reported high noise on New Years night but last night was marginally better with a sunrise enhancement, receiving CW from VO1NA on 477.7 kHz:

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!):

Neil, W0YSE, reported a strong session with several QSO’s.  He provided the following statistics and comments:

“Had a long CW Q with K7SF last evening on 475 kHz. He has a 50’ high flat-top with 3-65’ top hat elements and about 30 radials 75’ long. Steve is working on a 500w amplifier which will be more than sufficient to get him to max-eirp.

Later, I had “2.5” JT9 Q’s: N6PIG/7, KA7OEI, and a report from N1VF that I noticed too late to respond to. I also saw NO3M a few times with a best of -24.

Then, this morning I found these bits of Roger VK4YB on my JT9 screen:
1146 -27 -0.1 1102 @ DE VK4YB QG62
1312 -27 -0.0 1102 @ DE VK4YB QG62
1316 -26 -0.1 1102 @ DE VK4YB QG62

I also saw these JT9 call signs in addition to those mentioned above: VE7CNF, W7IUV, K0KE, VE7VV, KC3OL, KR7O, KC3OL, KC3OL, K5DNL

I could not get WSPRNET to work this morning, so no report on who decoded me, but I saw most of the above calls (except VK4YB) on my RX wspr screen this morning.”

Al, K2BLA, completed JT9 QSO’s with W3XY and ZF1EJ.  Once WSPRNet returned, Al reported incomplete values of “…heard by 30 and heard 17.

Ed, W0SD, completed remarkable low power JT9 QSO’s with K9KFR and NO3M.  Ed continues to work through some antenna issues that, once complete, will allow him to operate with a larger amplifier.  It is estimated that his TPO for these QSO’s was around 30 mW which must equate to an astonishingly low EIRP.

Brian, W1IR, completed a JT9 QSO with W3XY (second hand report).

Eric, NO3M, completed JT9 QSO’s with WB4JWM, W0SD and K5DNL.

Bob, K9KFR, reported a JT9 QSO with W0SD.

Ken, K5DNL, completed JT9 QSO’s with NO3M and WB4JWM.  Referring to Ken’s WSPR signal, Jim, W5EST, noted that “…post-SR qsb wspr2 swells occasionally peaking 10 dB above usual daytime level.”

Tom, WB4JWM, completed JT9 QSO’s with K5DNL, KC3OL and NO3M.

Ted, KC3OL, completed JT9 QSO’s with N1VF and WB4JWM.

William, N6PIG, completed JT9 QSO’s with KR7O and W0YSE.

Paul, N1BUG, reported QSO activity on 630-meters and expects to be active on JT9 seeking trans-Atlantic QSO’s in the coming days.  He submitted the following additional comments:

“I have been operating JT9 and CW on MF the past two nights. Easily worked VE7SL at 4048km. I have one, maybe two more nights before I must QRX to bring the variometer inside due to bad weather. I know it is late on the other side of the pond by the time we get darkness here, but if anyone will be up please look for me on JT9. It would be very nice to have a trans-Atlantic QSO in the log.”

Robert, KR7O, reported that he “Worked N6PIG on JT9.  Conditions seemed good, but very little activity.  Good signals from K9KFR and NO3M  on JT9.  W1IR was noted several times on WSPR.  VK4YB copied at least 13 times, best -17 on WSPR between 12-1300z and also up to -24 from 1316-1324Z on JT9.

Dave, GM3YXM, reported on the RSGB-LF reflector that “The evening started well with an early spot of EB8ARZ/1 at 2238 but then I didn’t see him again.  AA1A started coming in at 0040 and was last spotted at 0804! best signal of -23 was at 0234. EA7HPM from Seville was consistent all night, peaking -19 at 0330. Strongest non-G signals were from LA8AV and PA3ABK/2.”  He added that he would be seeking JT9 anf FT8 QSO’s later this evening.

Eden, ZF1EJ, completed a JT9 QSO with K2BLA.  Eden reported sixteen WSPR stations and he received reports from 45 unique stations including K9FD.

ZF1EJ session WSPR summary


Laurence, KL7L, indicated that he “… was off most of the night on tx – VK4YB on jt9 screen only – wx vy stormy and warm so played the safe card…sig levels to Hawaii were strong thru the night at times and PNW was reasonable.”  While on the air, Laurence received WSPR reports from seven unique stations. He shared two-way reports with K9FD.

Merv, K9FD (/KH6), reported ten WSPR stations. He shared two-way reports with KL7L. Merv received reports from fifteen unique stations including late reports from JE1JDL and JH3XCU.
