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

Current Operating Frequency and Mode

OFF AIR for storms - just one more night - should be QRV Saturday night!

Weird and unstable propagation punctuates unsettled session but great activity with a few notable benchmarks including K9FD (/KH6) -> K2BLA on JT9 and more than 100 WSPR stations reporting K5DNL; ARRL excludes (for now) 472 kHz and 137 kHz from 2018 Grid Operating Event but there is time to fix this and you can help!

HERE are a few mode-specific comments addressing where modes are located now and probably where they are best placed in the future

Curious about who is on the air making two-way QSO’s? Roger, VE7VV, is maintaining this list. If you complete QSO’s, be sure to let us know so he can add you to the active operator list.

Some coastal areas of North America were once again subject to lightning-rich storms, particularly along the East coast and Caribbean into South America.  The Mediterranean region continues to experienced strong storms in addition to parts of northern Europe into Scandinavia.  Japan is once again close to very active storms that may impact listening this morning and Oceania / western Pacific continue to experienced problems.  At least there are no damaging storms over the population centers along the eastern coast of Australia.  That’s not been the case in recent sessions.

Geomagnetic conditions remain at unsettled levels.  Presumably the coronal hole creating the most recent G2 storm is beginning to move out of view of the Earth, leaving us with unsettled conditions but I suppose additional storming is possible.  The Bz is pointing to the South this morning and solar wind velocities are averaging near 670 km/s.  DST values remain slightly variable at negative levels but like yesterday there have been no deep, sudden decreases associated with rapid, profound changes in the geomagnetic field.

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, reported a armchair-copy CW QSO early in the evening with Fred N3FL.  He also received a few trans-Atlantic WSPR reports.

Eric, NO3M, completed CW QSO’s with WW2LST and K9MRI.  He was quite active through the evening, receiving a large number of reverse beacon reports in addition to listening for JT9 and WSPR.

Joe, K9MRI, completed a CW QSO with NO3M and JT9 QSO with N3FL.

Roger, VE7VV, reported that he completed a JT9 QSO with K0KE.

Al, K2BLA, reported a strong night, completing JT9 QSO’s with three new stations including N3FL, K0KE and best DX of all, K9FD (/KH6).  Al added that he worked K5DNL, ZF1EJ, and KB5NJD for fun.  On WSPR he reported that he was “heard by 58 and heard 17. Nothing new or exciting in the WSPR mix.”

Ken, K5DNL, reported JT9 QSO’s with K2BLA, ZF1EJ, K0KE and N3FL.  On WSPR overnight, Ken had a record night for his station, receiving reports from 101 unique stations.  He reported 21 stations which was also a record for him.  He shared two-way WSPR reports with K9FD (/KH6), CF7MM and ZF1EJ.  Ken added that it was noisy at his station but propagation and activity were good.  Ken submitted this list of unique stations reporting his signal overnight.

Keith, K0KE, reported seven JT9 QSO’s during the evening with the furthest being K2BLA in Florida.

Rick, W7RNB, returned to air after a PC failure in the previous session.  He completed JT9 a QSO with AH6EZ at +13 dB / +10 dB S/N.  He operated WSPR overnight and his unique report details can be viewed here.

It was a weird night for propagation at KB5NJD that started with easy armchair copy of NO3M’s CQ’s on 473 kHz CW about 30 minutes before local sunset.  While its not the first time that this has happened, a review of notes suggests that when it does, the night can be very unpredictable.  That was the case during this session.  I was also observing another station that Eric was hearing at the same time on 473 kHz so this band behavior was not something necessarily related to his transmissions.  The signal in question was never identified.  As the evening progressed, W7IUV reported that my signal was building as he progressed through sunset.  I also observed that NO3M was weaker after sunset than earlier but suspect it was the presence of noise that was building  through the evening.  That brings up another point:  The character of the noise was odd and was clearly being propagated, changing fairly rapidly.  The best analogy I can find is that it felt like weather changes with the seasons but sped up to a time scale of minutes rather than months.  The band would be quiet one minute in a given direction and then moments later lightning crashes would be heard.  Another weird situation was that I still struggle to hear K9MRI.  Joe was hearing me well while I was not hearing even a single dit from him on any antenna.  Around this same time Eric, noted that I was as about as loud as he had ever heard me and supplied the recording below.  Listen to the instability and fluttery nature of my signal:


I contend that a high angle receive antenna might have been in order but aside from hooking up a low 80-meter dipole I was not prepared to do that last night.  I will work on that in the coming days.  The only other CW station that I heard during this session was WW2LST who was working NO3M earlier in the evening.  He was plenty loud but I suspect I was hearing him on a peak.  I called CQ hoping to catch him after he finished with Eric but never received a call and never heard the station again.  Maybe he was not hearing me or maybe like the situation with Joe, he was hearing me but I was not hearing him at the time.  Mark, WA9ETW, indicated that CW signals were down and he was only hearing me at RST 529 during evening.  He later added that he had heard another station around 473 kHz but could not identify it.  I don’t suspect that this station was NO3M.

I briefly operated JT9 so I could try to get a handle on propagation but only completed a quick QSO with Al, K2BLA, at -9 dB / -10 dB S/N.  That’s easy CW copy levels but no other stations were heard aside from a few audible WSPR stations.

Also notable was my inability to receive any reverse beacon reports in the evening and only one this morning.  It almost seems like unsettled geomagnetic conditions bring tougher propagation than storm levels sometimes where there is enough energy to increase absorption but not enough to enhance openings.  The morning session was much like the evening but as the band began to tilt with sunrise in the East I received a solitary report from AA4VV at a respectable 7 dB S/N.  I also ended the session on a high note with a nice ragchew with Rob, NC0B.  Rob has done a very nice job getting his station together and sounds fantastic on the air.  He is also personable and seems to enjoy a good conversation, which I can appreciate most of all these days.  I had to QRT at first light but Rob noted some QSB on my signal late in the QSO, so timing was good.  Overall the band was unpredictable and the noise was low but rapidly changing in character through the session which kept things interesting.

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

Roger, VK4YB, indicated that he received a report of his JT9 transmissions from K0TT.  He added that “High QRN from the Solomon Islands and Central Australia. No QSOs. WSPR 2[heard] / 29 [heard by] best DX, Jay KA9CFD.”  Roger received WSPR reports from CF7MM, JA1PKG, JA3TVF, JH3XCU, JR1IZM, KA9CFD, KJ6MKI, KL7L, KR6LA, KR7O, N1VF, NU6O, VA7JX, VE6JY, VE7AB, VE7BDQ, VE7CNF, W6SFH, W7IUV and W7IUV/W. He shared two-way WSPR reports with K9FD.

Robert, KR7O, reported fair transcontinental openings during the evening and overnight.  He indicated that he copied both sides of the  JT9 QSO between K9FD (/KH6) and K2BLA.  With WSPR he decoded VK4YB and K9FD (/KH6) once each during the session in addition to W5EMC, who was a new station for Robert, at -25 dB S/N at 200 mW (unclear whether TPO, ERP or EIRP).  He also reported AC7GZ for the first time.

Trans-Atlantic WSPR report details can be viewed here.  The trans-Atlantic WSPR summary follows:


Mike, WA3TTS, reported that he decoded nineteen WSPR stations overnight and added that he was using the

…NE EWE antenna early and NW EWE antenna late.  Dropped two large trees in my yard near my HF/160m vertical ground plane and have the four 65ft ground plane wires back in the air.  630m band seems quieter with the ground plane wires up, they approach the EWEs on their south end, unsure how much coupling interaction exists, but my WSPR waterfall now looks cleaner on 630m band. It will take a few days to weeks to determine what relative improvements were made…

Mike also submitted the following “Best DX” for 630-meters this session:

“K9FD   23 spots, best -14 @ 0726, min -28 @ 0841
W7IUV 8 spots, best -15 @ 0836, min -23 @ 1112
N6GN  2 spots, best -21 0634, min -22 0840″

Doug, K4LY, reported “Lots more activity than when I last was on 630M WSPR made for 75 unique spots of and 16 by K4LY in quickly reassembled 630M coil last evening.”  He also posted this Youtube link on the topic of operating ethics.

Ernie, KC4SIT, reported that he “Really noticed the increase of stations on 630. While propagation was a bit better last night with K9FD and I each decoding each other twice I couldn’t  believe my numbers on WSPR last night. I decoded 23 stations last night and 84 stations decoded my signal. Participation in 630 has certainly grown in the past month.

Joe, NU6O, indicates that he reported ten WSPR stations and received reports from forty unique stations.

The ARRL has posted this press release about their 2018 operating activity which sends mixed messages about whether MF and LF are included due to what is believed at this time to be clerical errors (different things are stated in the rules compared to the press release).  An email thread between me and Bart Jahnke can be viewed here.  While the ARRL  is currently excluding 472 and 137 from the event, Bart indicates that there is still time to get this done so it would be helpful if operators worldwide (its a worldwide event!) send a respectful email to Bart at contests@arrl.org and let him know that the ARRL should include both bands in this event.

There were 157 MF WSPR stations reported on the WSPRnet activity page at 0217z according to K5DNL.  Regional and continental WSPR breakdowns follow:

Laurence, KL7L, indicated that the A-index remains high and may take some time to return to normal as “poor-ish” band conditions continue.  Nevertheless he operated WSPR overnight, reporting seven stations including VK4YB and receiving reports from three unique stations after returning to transmitting following a few days of listening. Laurence shared two-way reports with K9FD and KR6LA.  Select DX report details can be viewed here.  Laurence also filmed a very good tutorial video which I have included as an instructional post which can be viewed here.

Merv, K9FD, (/KH6) operated JT9 last night and completed a nice, long distance QSO with an East coast station through crazy band conditions.  Merv explains:

Was on for about an hour or so last nite from 0400-0500Z.  When I first checked there were several strong JT9 signals on and in a few mins they faded off into the sunset.  But K2BLA spotted me on the chat room and he fired up again, we made a QSO at 0449.   Nice long haul over 4700 miles.  Then noticed QSB starting again and signals faded back to zero. Went to WSPR and did not see many signals there either.  So conditions were there,  QSB very slow,  but if you caught a peak contacts could be made.  Still some QRN out here,  weather says we have entered now into El Nino ??   Opposite of what we were any way and should mean more rain.

On WSPR overnight, Merv reported twelve stations, sharing two-way reports with VK4YB and KL7L. Merv received reports from 56 unique stations including 7L1RLL4, JA1NQI, JA1PKG, JA3TVF, JH3XCU, and ZF1EJ.  Select DX report details can be viewed here.
