Radio: it's not just a hobby, it's a way of life

Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

Good trans-Pacific openings allow VK4YB to share first time two-way reports with KR6LA and N1VF; Reasonably good trans-Atlantic propagation continues; KL7L returns to air after beginning antenna repairs following recent wind storm; First time WSQCall QSO for K1UTI with WB4JWM

There is a possibility that tomorrow’s report will be delayed or missed entirely due to an Internet issue.  I am working remotely to finish today’s report and it is not optimal so please bare with me until this problem is resolved.  I am trying to check and respond to emails at least once each day.  Any edits for today’s report will be delayed.


It was a quiet evening in North America followed by a noisy morning in the South as storms erupt along the Gulf coast.  Southern European and Mediterranean storms  diminished early during this session, leaving only a few isolated lightning-rich storms by morning.  Japan is active again, with wide spread storms in the central region of the country.  Most of the  eastern and southern population centers of Australia were lightning free and listening was somewhat improved compared to recent sessions.  The west central and northern regions were very active.  New Zealand was lightning free.

Geomagnetic conditions were quiet. The Bz is pointing to the North this morning and solar wind velocities are averaging near 330 km/s. Protons are exhibiting periods of elevated concentration from time to time which may be in conjunction with possible coming unsettled geomagnetic conditions.  DST values remain good at positive levels for persistent periods during this session.



Propagation was very good early in the evening, with a lull mid evening for many followed by a relative strong overnight period.  Trans-Pacific openings allowed two-way reports for a couple of new stations.  Trans-Atlantic openings remain very good.

Reverse beacon network reports follow:

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!):

Tom, WB4JWM, reported JT9 QSO’s with K9KFR, K9MRI, KC3OL and K9KFR.  Using FT8 he worked K9KFR and using WSQcall for the first time, he worked W1IR and  K1UTI.

Bob, K9KFR, reported CW QSO’s with K4EJQ, KB5NJD and W3TS.  He worked  KC3OL and WB3AVN using FT8 and he worked WB4JWM, WB0DBQ, KC3OL, N3FL using JT9.  Bob wonders, “What happened to all w7 land?

Al, K2BLA, reported that he “…Worked K9MRI last night. On WSPR: heard by 52 but nothing over 4000km. Heard 22 no real “DX” there either. Lightning crashes suddenly built up this AM probably from a cold front making its way across the Gulf and heading here late this afternoon.

Bob, K1UTI, reported that he “… had my 1st WSQCALL contact with WB4JWM Tom last night @ 04:38z on dial frequency of 472.5 khz. Signals were very stable over the 444 mile path at least for the duration of our qso. Left things running overnight and copied W1IR but that was after I had gone to bed. Good thing about the mode, with SELCAL turned on, is that people can still ping you for a signal report.

Ken, K5DNL, indicated that while operating WSPR through this session, he reported 25 stations and he received reports from 98 unique stations including KL7L, ON5KQ,  F59706,  YV7MAE and ten Canadian stations.

Robert, KR7O, reported,

“Another noisy night, but it was mostly quiet by 12Z.  On JT9, I copied the following TC signals:  K9KFR (evening) and K2BLA around EC SR.  Only a few west coast stations active.  On WSPR, copied the following TC stations:  WD8DAS (2/-26), N4WLO (5/-23), N1DAY (9/-21), KC4SIT (42/-16), K4LY (8/-20), K2BLA (-22), W3LPL (4/-27), W4BCX (13/-22) and ZF1EJ.  Except for a couple of SE stations, no TC before the 05-06Z hour.

ZF1EJ 3 spots, -22

KL7L 62 spots, -7

VK4YB 26 spots, -20

Later in the evening N1VF inquired about a mystery CW signal around 474.720kHz.  I had noticed that earlier (and maybe previously), but wrote it off as a birdie.  I fired up ARGO and QRSS3 appeared to provide the best visual of the signal.  I could see and sometimes hear the four dashes, but the dits all ran together and with the QRN and QSB, they would sometimes saturate the display, masking the other dits.  I was still copying this signal at 12Z, but much weaker, even though the QRN had subsided significantly.  Unfortunately, I did not turn on capture as intended to analyze the signal any more.”

Mal, G3KEV, reported  that “Last nite results good but not unusual, had reports from AA1A, KA1R, VE1YY.  Transatlantic contacts seem a regular occurrence at present on MF between the UK and N.America.  Most operators are using WSPR but more CW both normal and QRSS would be welcome like it used to be some years ago, ie real QSO mode.

Doug, K4LY, indicated that he received reports from “…89 including best DX LA2XPA is more than I remember in past when I was running more TPO….

John, VK2XGJ, reported that “…after spending the last couple of days/nights on WSQCall and not printing anything I have changed back to WSPR and JT9 for the night.  I don’t expect to print anything outside VK as there is too much noise for anything else.

During this session, KB5NJD worked K9KFR.  Bob had a very nice, in-the-clear, signal and a true RST 569.  I made a few additional calls  but only received reverse beacon network reports.  K3MF reported that he called me but I never heard him at the time.  QSB was active as K4EJQ ranged from  nothing to S7 through the evening with relatively fast transitions.

Laurence, KL7L, has begun to assess antenna damage from strong storms and high winds in Alaska.  Laurence submitted this photo of his 10-foot receive loop located in the woods.  Laurence indicates that the probes and single-turn loop remain operative.  He added that “Ive pulled down the remnants of the Marconi and some salvagable – pulled apart some pretty thick ropes – its a toss up whether the trees hold up the array or I keep the trees upright!

Using WSPR, Laurence reported five stations.  He was able to make some repairs and has returned to transmitting, receiving reports from seventeen unique stations including  JA1PKG and JH3XCU.  He shared two-way reports with VK4YB.

Roger, VK4YB, reported first time WSPR decodes (and two-way reports, actually!) of N1VF and KR6LA and submitted these comments and a screen capture:

“…The band was quiet for a change. The storms were well to the North and West. Signals began to appear. I had almost forgotten what they look like. The first decode was KL7L, quickly followed by N1VF, a new one for me. Then KR6LA also a new one, I believe. It was 2way with those 3 stations. Amazing what can be done if the QRN gives you a break, and this is only early February. N1VF was also decoding my JT9. It will not be long before 2way JT9 QSOs with these stations is achieved. (KL7L is already in the bag). There were many WSPR decodes by K0KE and one from K5DNL. Alberta stalwart VE6XH also had WSPR and JT9 decodes.  All in all a very good session and augers well for the Equinox.

Using WSPR overnight, Roger reported three WSPR station (N1VF not uploaded) and he received reports from 26 unique stations.  He shared two-way reports with N1VF, KR6LA and KL7L.
