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 activity and plentiful domestic openings during the evening while trans-Atlantic paths regressed a bit; Noise on the increase in North America while conditions improve significantly in Australia

Most of the North American mainland was lightning free during this session although a few evening storms were present in the Northwest.  Pacific storms remain off of the Mexican coast and a few evening storms were present at sea off of the mid Atlantic coast.  Parts of northern Europe experienced storms while much of the continent was lightning free.  Japan experienced isolated storms in the central region of the country.  Australia was relatively storm free after weeks of very active weather conditions.  A few storms remain in population centers in the East, North and central interior.  New Zealand is experiencing a few storms on the south island as another system approaches from the West.

11-hour worldwide lightning summary


Geomagnetic conditions are quiet although the Bz is pointing solidly to the South this morning.  Solar wind velocities are averaging near 350 km/s. DST values are good as they remain above the centerline at positive levels.




Propagation was reported to be good through the evening although QSB was very high on a number of paths.  Noise seemed to increase as the evening progressed, however.  Trans-Atlantic paths were also down and largely reported in the Northeast.

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!):

John, WA3ETD, reported heavy QSB in the hour following his local sunset but he completed JT9 QSO’s with WB3AVN, WB4JWM, K2BLA, K3MF, KC3OL, K9SLQ and VE3CIQ.

Tom, WB4JWM, reported JT9 QSO’s with K2BLA, WA3ETD, N9RU, WB3AVN, K3MF, WA9CGZ, KC3OL, K9SLQ, VE3CIQ, K5DNL and  K0KE.  He completed FT8 QSO’s with K9MRI and K9KFR.

Joe, K9MRI, completed JT9 QSO’s with WB3AVN and K2BLA.  He worked WB4JWM using FT8.

Wayde, K3MF, reported JT9 QSO’s with N9RU, WB4JWM, WA3ETD and KA1AL.

Ted, KC3OL, reported JT9 QSO’s with NO3M, WA3ETD and WB4JWM.

Ken, K5DNL, reported JT9 QSO’s with WA1OJN and WB4JWM.  Using WSPR overnight, he reported 22 stations and he received reports from 86 unique stations including KL7L, F1AFJ, YV7MAE, ZF1EJ and seven Canadian stations.

Al, K2BLA reported that he “Worked WB4JWM, K9MRI, WA3ETD, WB3AVN, K3MF AND W3XY on JT9. WB3AVN is a new station for me but, unfortunately not a new grid. ( a lot of stations in FM19) WSPR: heard by 51 including YV7MAE. Heard 16; a lot of PNW. Low noise last night, moderate noise this AM but no lightning the past 24 hours.”

Rob, KR7O, reported high propagated noise that dissipated after sunrise.  He submitted the following comments and statistics:

Pretty much a repeat of the last few sessions.  K9SLQ, NO3M, K9KFR were copied on JT9 along with a couple of western stations.  On WSPR, copied TC stations N4WLO (5/-22), N1DAY (9/-23), K4LY (-26), K2BLA (-23), W3LPL (19/-23), VE3CIQ (2/-27) and W4BCX (10/-23).

VK4YB 6 spots, -25

John, VE7BDQ, reported at 0100z that VE7VV was operating FSQ.  VE7CNF reported at 0240z that “VE7VV and VE7CNF running FSQCall in SELCAL mode, dial=476.3 for a while testing auto SNR queries.”  John indicated that he was only decoding Toby’s signal during the evening but noted just before 1000z that he had good copy on all stations.

There was very little activity from KB5NJD during this session as I continue to work on a time-sensitive project but I did monitor JT9 in the early evening, receiving a large number of stations as the band was in good shape and signals were strong.  At three different times during the evening I sent a CQ on CW and each time received a reverse beacon report.  No additional callers were noted but I wasn’t really looking for a QSO in spite of my calls suggesting the contrary.  My station was not active this morning due to schedule conflicts.

Roger, VK4YB, reported this morning that “There is a cool change just coming through Brisbane now with a line of thunderstorms. The rest of VK appears clear. Early TP is weak…The band recovered from the low start and TP signals are back to normal now. That has been the pattern over the last few days. My JT9 was decoded by KL7L and VE6XH.”  Using WSPR, Roger received reports from 21 unique stations including 7L1RLL4, JA1PKG, JA3TVF, JA5AEA, JR1JDL, K6SRO, KJ6MKI, KJ6WSM, KL7L, KPH, KR6LA, KR7O, SWLCN74XP, VE6XH, VE7BDQ, WA6OURKIWI, WB7ABP.

VK4YB session WSPR summary


Laurence, KL7L, indicated that gale-force winds continue in Alaska so he remains in a receive-only capacity until such time that he can make repairs to his top loading.  Laurence noted that this morning there was an “Auroral arc to some 20 degrees above the horizon to the North.”   He reported six WSPR stations including VK4YB and K5DNL.
