Current Operating Frequency and Mode

Probably QRT tonight and in the morning due to storms in the area

Poor domestic openings but higher favorability in some longer-haul paths; Unsettled geomagnetic conditions return with elevated solar wind velocities; Noise remains very high across the Pacific; W5EST presents: ”Whadda Ya Know! Serious 630m/2200m Info!”

It was fairly noisy in North America during this session due to a system in the Midwest that was particularly active this morning.  Storms continue to impact coastal areas of the Northwest in addition to the central Atlantic into the Caribbean.  The Mediterranean  and parts of Scandinavia continue to experience lightning but Europe was generally in the clear.  Lightning was active from Japan South across widespread areas of Oceania.  Most of the population centers in Australia are being impacted.

Geomagnetic conditions are at elevated-quiet levels with Solarham reporting unsettled levels possible at any time now.  The Bz has been variable but generally pointing to the South and solar wind velocities are averaging near 400 km/s.  Proton concentrations have been elevated to moderate levels this morning.  DST values remain at negative levels.  The A-index is currently at 11, suggesting elevated absorption is possible at higher latitudes.  As reported by KL7L recently, an A-index of 8 or better is preferred.

 

 

 

Propagation was very poor during the evening and this morning with periods of elevated noise reported around North America.  Signals were significantly weaker than in previous sessions in spite of the fact that geomagnetic data do not appear to be too terrible on the surface.  As one study recently reported, solar storms often leave the ionosphere depleted of the constituents necessary to support quality propagation.  Perhaps that is what is happening here.

Phil, VE3CIQ, reported a JT9 QSO with K9MRI.  He also reported good transcontinental conditions on WSPR, with reports from VE7, VE6,VE4 and  W7IUV.

Ken, K5DNL, reported a JT9 QSO with WA9CGZ.  Using WSPR overnight, Ken reported nineteen stations including VK4YB and K9FD (/KH6).  He received reports from 96 unique stations.  He shared two-way WSPR reports with VE3CIQ and ZF1EJ.

Keith, K0KE, reported that band conditions were so poor that he thought he had a problem with his system until he finally completed a JT9 QSO with CF9MM at -24 dB S/N.  At 1200z he reported VK4YB at -25 dB S/N.  Keith added that band conditions seemed better when the K was 5 which may have been the case in the midst of an onset enhancement.

This was a very poor session at KB5NJD.  Typically if an evening is extremely poor, there are often improvements by morning but that was not the case during this session.  Reverse beacon network reports were almost impossible to come by although I see that one report was registered at AA4VV just prior to 0200z.  K4EJQ was weak during the evening which is never a good sign and NO3M indicated that my signal was down significantly from where it has been in recent session.  Noise was high at 1015z when I began my morning operating session  but that subsided by 1045z and virtually no lightning crashes were heard which may be a bleak commentary on propagation.  This too shall pass.

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 “K9FD made it through the QRN for the only single WSPR decode of the night at 11.50z (-26). There may be more spots nearer Hawaiian sunrise.  There were 24 WSPR receiving stations, KU4XR was the best DX. I believe KT5H and K5DN were new ones. K5DNL also had several spots.  My JT9 reached as far as the Alberta twins. I was sending ‘DE VK4YB QG62’, which means ‘Don’t bother calling, my QRN is way too high’.”  Roger was also reported using JT9 by VA7MM at 1203z at -27 dB S/N.  Roger received WSPR reports from JA3TVF, K5DN, K5DNL, KJ6MKI, KPH, KR6LA, KR7O, KT5H, KU4XR, N6GN, VA7JX, VE6JY, VE6XH, VE7BDQ, VE7CNF, W7IUV/W and W7WKR. Roger reported K9FD (/KH6).

Robert, KR7O, reported Low activity during the evening.  Signals down in general for the western stations.  Only 13 stations copied with only W8RUT and K4LY from farther than 2100km.”  Robert’s best DX for the session includes:

“ZF1EJ 3 spots, -27

K9FD 89 spots, -1

KL7L 32 spots, -18

VK4YB 33 spots, -18   0930-1246Z.  Many low -20 spots this session.

Paul, N1BUG, reported  WSPR signals from fifteen stations including G8HUH and ZF1EJ.

Mike, WA3TTS, reported that he “Heard 20 stns overnight 630M incl K9FD(8 spots), N6GN(6) CF7MM(1) AH6EZ(2) ZF1EJ(18)”

There were 166 MF WSPR stations reported on the WSPRNet activity page at 0100z.  Regional and continental WSPR breakdowns follow:

Eden, ZF1EJ, reported twelve WSPR stations including K9FD and he received reports from 63 unique stations.  No JT9 activity was reported for the session.

Laurence, KL7L, reported that attenuation remains high in the medium wave spectrum as local and remote broadcast signal are down.  Laurence indicated that he “…converted the 137tx 500ft circumference loop to 475kHz last night- something Ive done a number of times over the years  – the aim to compare its effectiveness in Winter over the Marconi…”  He added that results, at least on DX paths, suggest that the loop at his location is down at least five dB, in some cases more but notes that there are a lot of factors involved, including interaction between the Marconi and the loop as well as very different launch characteristics.  Laurence has observed similar results in the past as he has performed this test many times before from his inland location near Anchorage.   He is continuing his experiment this morning in the pre-dawn period, switching manually between antennas as he calls CQ with JT9, but he indicated at 1628z that the path to JA may have already closed.  Further comparisons will be performed in this regard in the future.

Using WSPR overnight Laurence reported five stations including K9FD and he received reports from sixteen unique stations including JA1PKG. He shared two-way reports with KR6LA, N6GN and W0YSE.  Select DX report details can be viewed here.

Merv, K9FD (/KH6), indicates a near “white out” on his waterfall but apparently he received WSPR stations that did not upload to WSPRNet.  He is investigating.  Using WSPR he received reports from 44 unique stations including 7L1RLL4, JA1PKG, JA3TVF, JH3XCU, JR1IZM, VK2XGJ, VK4YB, ZF1EJ and ZL4OL.  Select DX report details can be viewed here.
