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

A number of QSO’s were reported through perilous QSB including transcontinental JT9 between W7IUV and WA3ETD; Late reports of VK4YB by KR7O and W7IUV; Quiet geomagnetic conditions but very high noise from storms in southeastern US; Strong storms blanket some population centers in Oceania

The southeastern US was once again awash with storms  that ranged from the Yucatan of Mexico into the mid-Atlantic region.  Noise stretched well into the central US during the evening and the situation was not much improved this morning.  Europe is also active with lightning-rich storms this morning, including the Mediterranean region, which received a bit of a reprieve in the previous session.  Oceania remains very active including the south island of New Zealand and eastern coastal Australia.

Geomagnetic conditions were quiet.  The Bz is pointing slightly to the South this morning and solar wind velocities  are averaging near 400 km/s. DST values are riding the center line, showing significant improvements and stability compared to recent sessions.

 

 

 

Evening propagation was OK after dark with transcontinental openings reported between Washington state and Vermont.  The main propagation issue was QSB, which was really challenging when coupled with the elevated noise levels.  As with previous sessions, higher angle signal seemed to dominate at least at my station in North Texas.  The band seemed poor this morning although late openings to Oceania were reported by western stations.

Reverse beacon network reports follow:

 

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!):

Eric, NO3M, reported a CW QSO with N3FL and added that Fred sounded louder than in past QSO’s in spite of elevated QRN and QSB.

Fred, N3FL, reported “…good  propagation… Eric, NO3M, was 599+ at my QTH (S9 on the IC-7100 S Meter and no preamp)! That is the strongest signal that I have heard on the band to date.”

John, WA3ETD, completed a transcontinental JT9 QSO with W7IUV through difficult QSB during a sunset enhancement in the West.  John also completed a JT9 QSO with K9MRI.

Joe, K9MRI, completed JT9 QSO’s with WB4JWM, N3FL, KC3OL and KA9OKH.  Joe also reported CW from my station at RST 529.

Larry, W7IUV, completed JT9 QSO’s with VE7VV and W0YSE shortly after sunset and WA3ETD in Vermont after dark.  Larry indicated that this was a sunset enhancement.  This morning  he was hearing VK4YB later than normal.

Ken, K5DNL, completed JT9 QSO’s with WB4JWM, W9XA and W8RUT. Overnight using WSPR, Ken operated in a receive-only capacity, reporting fifteen stations on what was a very crowded band.

Al, K2BLA, reported that he “…only operated a short time last nite before severe T storms roared thru. wkd 1 on JT9 in spite of noise, WB4WJM WSPR: hrd 12 hrd by 34…

Robert, KR7O, reported at 1345z that “VK4YB just popped in -28. Don’t normally copy him this late…don’t normally copy Roger after about 1300z. Seems 10-13Z the prime time without going through the logs.”  Robert also noted that “Some regional JT9 activity in the evening, but nothing over 2200km.  One spot of W9XA (-29) was the only thing close to TC all night.

ZF1EJ 1 spot, -27

K9FD 81 spots, -6 

VK4YB 3 spots, -25

Keith, K0KE, reported WSPR decodes from K9FD (/KH6) at -15 dB S/N at 0924z.

Paul, N1BUG, built this very fine looking variometer and matching transformer, which seems to be doing very well on the air.  It uses a sliding internal coil.  This looks like a work of art.  Well done, Paul!

This was a relatively poor session at KB5NJD.  Signals were weak and mostly high angle  but a few bright spots were observed including loud copy of Eric, NO3M, calling CQ and working Fred, N3FL.  Fred was lightly detected at my station for what is likely the first time.  Have upgrades occurred at Fred’s stations or was this just propagation?  It was noisy to the East and noise moved around in step with the QSB.  No reverse beacon reports were registered by my station and this was particularly surprising this morning but I got a bit of a late start which may have contributed.

Laurence, KL7L, continues in a receive-only capacity back in Alaska, reporting four WSPR stations including VK4YB and K9FD.  Laurence also reported K9FD as KL7L/KH6 and indicated that Merv’s signal experienced far fewer excursions in signal level than in recent sessions.

Merv, K9FD (/KH6), reported eight WSPR stations. He shared two-way reports with VK4YB, KR6LA, NU6O, W0YSE and W7IUV.  Merv received reports from 41 unique stations including 7L1RLL4, JA1PKG, JA3TVF, JE1JDL, JH3XCU and KL7L.
