Significant improvements during this session with VE7BDQ, VE7SL –> WG2XIQ and WG2XIQ –> WE2XPQ in KL7

– Posted in: 630 Meter Daily Reports, 630 Meters

It would be difficult for me to make many negative comments about this session.  The noise started out high but there were numerous single digit S/N reports of my signal and I was hearing better than I have in some time with reports of VE7BDQ and VE7SL, both in British Columbia.  That’s not a big deal in December but it is July, after all, with storms on all fronts.  WSPR spot totals were four times higher than the previous session and my signal even reached WE2XPQ in Alaska once, something that has not happened in a few months.  The summer is always weird for the high latitude paths and often yields more reports to KL7 than most other seasons.  It makes no real sense given that its still not getting dark in Alaska  – go figure!

Geomagnetic activity saw significant levels of solar wind, exceeding 600 km/s, and the Bz was persistently pointing to the South:

Australia 071616


Rick, W7RNB / WI2XJQ, has completed additional improvements at his stations, reporting in excess of 1.3 watt ERP.  John, VE7BDQ, reported the CW signal at RST 579 in a 2.1 kHz bandwidth, which was very noticeable compared to previous reporting periods.  Toby, VE7CNF, reported the signal at RST 559 at S2 – S4 with QSB and QRN.

Neil, W0YSE/7 / WG2XSV, reported seeing WI2XJQ and VE7SL and offered this screen capture:

WG2XSV 071616


Neil also reported that he decoded WSPR signals from VE7BDQ, VE7SL, WG2XIQ, WH2XCR and WH2XGP ( several times each !!)  Neil was decoded by  N6RY, NO1D, VE7BDQ, VE7KPB, VE7SL and WH2XGP.

Steve, VE7SL, reports that he decoded six WSPR stations and was decoded by twelve unique stations including several reports from the East. Steve also notes that he decoded WH2XCR twelve times compared with zero during previous night.

Larry, W7IUV / WH2XGP, reports a much better session than the previous night but receive conditions continue to be poor at his QTH.  He decoded five WSPR stations and was decoded by 21 unique stations.

Merv, K9FD/KH6 / WH2XCR, reports high noise in the Pacific and offers these comments:

“Hurricanes stacked up 3 or 4 deep headed from Mexico area to
KH6.  Remnants of one just passing,  another one will pass here for the
weekend,  lots of QRN,  especially towards US.

Will see what tonight and the weekend brings.  at least no strong
winds now for a few days,  back to normal so to speak.

Have a good weekend sir.   73 Merv K9FD/KH6″


Roger, VK4YB, reports that his noise level started at -77 dBm and improved to -84 dBm, as measured with a Siemens D2008 Pegelmesser in 1.7kHz bandwidth at the antenna input.  Roger reports that DX may be possible during this session.

Regional and continental WSPR breakdowns follow:

North American 24-hour WSPR activity


EU 071616

European 24-hour WSPR activity


VK 071616

Australian 24-hour WSPR activity


JA 071616

Japanese 24-hour WSPR activity


There were no reports from the trans-Atlantic, trans-African, or trans-Equatorial paths.  UA0SNV was present but no reports have been filed at this time.

In the Caribbean, Eden, ZF1EJ, once again reported my station during the session:

Laurence, KL7L / WE2XPQ,  experienced a pretty good session with reports of stations in the Pacific Northwest / British Columbia, Hawaii, and as previously reported, my signal, which has been relatively rare over the previous few months:

WE2XPQ 071616

WE2XPQ 24-hour WSPR activity


WG2XIQ WE2XPQ 071616

WG2XIQ, as reported by WE2XPQ


WH2XCr WE2XPQ 071616

WH2XCR, as reported by WE2XPQ

Merv, K9FD/KH6 / WH2XCR, reported noise from a string of hurricanes but still managed to hear VK4YB.  Interestingly enough, however, Roger reported quieter band conditions but had no reports of Merv during the session.  It just goes to show that while noise is important, it doesn’t matter if the band doesn’t open:

Jim, W5EST, presents a discussion entitled, “HIGH LATITUDE DAYTIME 630M PROP”:

“Today’s 4-way dialog comes from Steve VE7SL writing in—most appreciated!

Steve VE7SL: Jim, for what it’s worth, up here I hear NDBs (non-directional beacons) from Ontario during the day (usually always in winter). I have always assumed it due to D-layer so highly ionized that it is either ducting or doing something along those lines. Invariably, eastern signals during the daytime always lead to absolutely nothing during the night [by way of enhanced reception]. I’ve noticed this a lot over the years. The daytime propagation always follows a flare or some large geomagnetic disturbance. I believe this is unique to higher latitude locations as the same effect is not reported further south.

Laurence WE2XPQ: I agree, Steve.

Jim W5EST: Yes, need to know what’s unique to higher latitude locations.  Last Feb. 27-29, 2016, this blog compiled daytime propagation days and non-prop days vs. flares/no-flares for the season in lower-48 USA only.  For higher latitude, wouldn’t some continual 630m day-after-day data help by listing daytime propagation yes/no, flare yes/no, geomagnetic disturbance yes/no, particle shower yes/no.  Flare/geomagnetic–makes sense higher latitude–even though I couldn’t find a correlation of flares with lower latitude 630m daytime propagation data.

Wouldn’t you think higher sun at lower latitude would make a flare ionize the D-layer more fully than at high latitude, not less!  137KHz WH2XND-w7iuv WSPR SNRs have showed pretty consistent daytime propagation with some increase around solar noon, consistent with D-layer propagation.

Steve VE7SL: Regarding higher sun angle down south in USA, I think it’s more a case of us being under the geomagnetic influence and auroral zone than further south.  Even the slightest geomagnetic hiccup sets propagation askew up north here. Go just a couple of hundred miles to the south and everything is normal!

Larry W7IUV: Amen to that Steve!

Jim W5EST:  Thanks! Any closing comments?

Steve VE7SL: Larry…helps to be a little crazy to be an LFer in the Pacific NW … totally nuts in KL7!  :-))”
