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!

Another weird night of propagation as unsettled conditions continue but a few periods of high activity observed on JT9 and CW; VK4YB’s JT9 reported by many North Americans but increasing noise in VK doesn’t permit a QSO; Evening crossband CW at W0RW; Anyone have a problem with designating 472.5 kHz as the CW calling frequency for NA?

The UTC amateur registration database is here.

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.

Lightning conditions are similar to previous sessions although reports from the Northeast suggest that Atlantic storms are creating listening problems.  A few evening storms were observed in the Pacific Northwest and an flare-up along the Texas Gulf coast was observed this morning as well.  The Caribbean  and Yucatan continue to experience nightly storms, presumably associated with the monsoon.  The central Mediterranean  continues to experience strong storms for the fifth consecutive day and spotty activity is observed in northern Europe, all contributing to generally elevated noise levels.  The western Pacific continues to see strong storms with Japan now separated from open water by a strong system that appears to be moving East and out to sea.  Central Australia is the focal point of noise on the continent and is impacting listening in population centers in the East.  For what it’s worth, it was quiet in North Texas last night and this morning both to the East and the West.

Geomagnetic conditions are improving but remain at elevated-quiet to unsettled levels. The Bz is pointing slightly to the South this morning and solar wind velocities have decreased below 600 km/s, now averaging near 540 km/s.  DST values are cycling but continue at relatively stable levels and are approaching persistence near the centerline.




Propagation was less impressive overall than previous sessions but there were a number of bright spots.  QSB continues to be deep and higher latitude absorption continues to be a problem for a number of stations.

Frank, W3LPL, proposes that we set up a CW calling frequency.  In Europe that frequency is 472.5 kHz and it seems like it might be OK to do that here as well on the same frequency.  Frank added that “…Following the VHF calling freq tradition, brief QSOs are okay on the calling freq, rag chews should QSY.”  Any thoughts or comments on using 472.5 kHz or another frequency for a calling frequency in North America?  I plan on parking my receiver there when not specifically on a working frequency and see how it goes.[UPDATE] – we are back to the drawing board on this as many have birdies on 472.5 kHz.. stay tuned for further updates!

Jim, W5EST, submitted the following screen captures showing JT9 activity received at his station in Little Rock, Arkansas (click to enlarge – use the Back button to return to report):









Brian, WA1ZMS, was active with a CW beacon on 472.16 kHz right at the band edge and was received by a number of stations along with eastern seaboard.  He peaked briefly above the noise here in North Texas at 0104z but the signal was far before QSO limits at the time due to QSB.

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!):

Joe, K9MRI, completed JT9 QSO’s with NC0B, KC4SIT and KB5NJD.  He also completed a CW QSO with KB5NJD.  More details on that in my section lower in this report.

Larry, W7IUV, completed JT9 QSO’s with NC0B and KB5NJD.  Larry reported high noise and weaker signals, likely due to continued high-latitude absorption.  With WSPR, Larry reported VK4YB on both of his receivers.

Al, K2BLA, reported that he completed a single JT9 QSO with NC0B and he received WSPR reports from 37 unique stations after just one transmission.  He indicates that his operating time was very limited during this session.

Rick, W7RNB, reported a JT9 QSO with VE7BDQ at -2 dB / -2 dB S/N.  Rick’s unique overnight WSPR details can be viewed here.

John, VE7BDQ, reported JT9 QSO’s with NC0B at -22 dB / -24 dB S/N, W7RNB and VE7CNF.

Mark, VA7MM, reported JT9 QSO’s with K9FD and NC0B.

Ken, K5DNL, reported JT9 QSO’s with K0KE, NC0B, NO3M and WA9CGZ.  Ken noted that the QSO with K0KE occurred during the day at a distance of about 500 miles.  Using WSPR overnight, Ken reported nineteen stations including VK4YB and he received reports from 91 unique stations.  He shared two-way WSPR reports with K9FD (/KH6) and ZF1EJ.

Paul, W0RW, was operating cross band CW, transmitting on 473 kHz and listening on 3555 kHz.  Paul completed a simplex QSO with me but I don’t have details about whether he received any cross band calls.  He posted his intent to operate on QRP-L.

The evening session started slightly weaker than the previous as my pre-sunset reception of NO3M was no longer armchair copy.  The band was slow to develop but may have been related to spurts of activity which can happen on Friday evenings as people may have other priorities early in the evening.  A few WSPR transmissions suggest that the band was in good shape but not quite as good as the previous session.  Mid-evening brought a flurry of JT9 activity where I completed QSO’s with K9MRI, KC4SIT, K0KE and W7IUV.  I also completed CW QSO’s with W0RW (simplex) as he was operating cross band and finally a CW QSO with K9MRI.  Joe and I learned that the problems we had in the past were related to us being on opposite receive sidebands.  I knew there had to be a logical explanation.  With the FT1000, I select “CW-U” which gives a USB receive offset in order to remain in harmony with nearby digital modes.  In Joe’s case he needed to select CW-REV with his TS-2000.  I made a few additional calls but QRT’ed by 0315z for the night.  I should also mentioned that I heard brief calls from KC4SIT that were registered by the reverse beacon network but he returned to WSPR and JT9 before I could call him.   I was late getting to the ham shack this morning, which is often the case on Saturday.  I was QRV by 1010z and made a few calls on 474.5 kHz CW, receiving respectable reports from a number of reverse beacon nodes in the East as well as VE6.  I heard NO3M swoosh across the freq a few times as he was troubleshooting a problem but no additional QSO’s were completed.  The band was open, there were just no warm bodies.  I received an email report from Carl, WA8ZTZ, in Rochester, Minnesota who indicated that I was heard at RST 559.   Carl indicates that he is using an “Alinco DX-SR8T (has general coverage RX with good sensitivity on LW) and PAR EF-SWL antenna.”  I QRT’ed during twilight, receiving only one additional RBN report from VE6WZ.  Typically when it begins getting light, the band is done.

Laurence, KL7L, indicated around 0700z that he was transmitting a bit of JT9.  Laurence indicated that “…JT9 screen bare except 1102 -26 0.1 1118 @ CQ VK4YB QG62, 1108 -25 0.2 1118 @ CQ VK4YB QG62.”  Overnight using WSPR Laurence reported seven stations including VK4YB and he received reports from ten unique stations.  He shared two-way reports with K9FD, KR5LA, NU6O, W7IUV and W7RNB.  Select DX report details can be viewed here.

Merv, K9FD (/KH6), submitted these comments about his evening JT9 activity:

Got on about 0330Z for a listen to JT9 before sunset.  Band was in super good condition and at sunset died down to normal.

Worked Rob NC0B in broad daylight 0350Z I logged him that was after I miss keyed and missed him the first time.  He had super signal -8 steady as a rock, then worked CF7MM Mark at -12.

Called K5DNL for 30 mins and he didn’t see me.  He was up to -15 at times. QSB was bad by then and he would dip to -26. That was 0430z to 0500Z.  What was interesting as I kept calling K5DNL,  Rob NC0B said I was up to -17 at his QTH.  Either some large differences in propagation or some large differences in reception.

Heard NC0B work ZF1EJ but not a trace here on Eden tonight.  Seems QRN is picking up and band is pretty iffy.

Using WSPR, Merv reported fifteen stations including VK4YB. He shared two-way reports with VK4YB, KL7L and ZF1EJ.  Merv received reports from 52 unique stations including JA1PKG, JH3XCU, JR1IZM and ZL2BCG.  Select DX report details can be viewed here.
