Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

Quiet geomagnetic conditions and ‘OK’ propagation but more storm noise in parts of North America as the southern hemisphere turns to Winter and trans-Pacific openings hang on for another night; Some areas reporting best S/N in weeks

– Posted in: 630 Meter Daily Reports, 630 Meters

The details for June 1, 2016 can be viewed here.

IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet.  Please continue to be patient and let the FCC finish their processes.  Click here to view the proposed “considerate operators” frequency usage guide for 630-meters under Part-97 rules that was developed with the input of active band users.

This session was characterized by more widespread storms across the continent which translates to more noise for many stations that are able to get on the air through such conditions.  A number of stations reported below average noise, however, with reports being completed for the first time in weeks or S/N levels that were more on par with what is observed in Winter.

Geomagnetic conditions were quiet again with a North-pointing Bz and solar wind velocities averaging near 350km/s.  DST values are favorable and at positive levels for a change.  Proton levels are elevated, however, into the moderate category this morning.




Al, K2BLA / WI2XBV, indicated that he experienced some of the best S/N levels in several weeks.  Lightning crashes were present but the spacing was wide enough that signals were largely unaffected.  This noise behavior was different from the previous session which he characterized as “wall-to-wall noise”.   Al provided reports for four WSPR stations.

Roger, VE7VV, reported better propagation and lower noise in British Columbia as he received his first WSPR report in two weeks from VE6XH at a distance of 879 km.

Larry, W7IUV / WH2XGP, indicates that he experienced high noise, making testing of his receive system repairs difficult.  He provided reports for two WSPR stations and he received reports from 24 unique stations.  As W7IUV, Larry provided reports for five WSPR stations.

Phil, VE3CIQ, reported that he decoded two WSPR stations and was decoded by eight unique stations while using 40-watts TPO.  Phil also had an interesting non-630-meter item that may be of interest to the WSPR community and I have included that information at the end of this report.

Al, WD4AHB, indicates that he provided first time reports for WI2XUL.  He also reported WH2XZO, WH2XXC, and ZF1EJ.

Mike, WA3TTS, reports “Results slightly improved over previous evening. 9 stations decoded on 630m. Ran with SE antenna after sunset and then switched SW around 0300 to SR…possibly more local background noise to SW direction vs. my NW direction (which historically has been quietest direction on 630/2200m bands), no decodes under -27 overnight.  I think XGP and XUL would have been a few dB stronger on my NW antenna direction, but I did not take the late night walk to the outdoor antenna switches for the NE NW direction options…”

Mike added:

“Also ran dual band with hybrid combiner on IF output of LF/MF converter, 43 WH2XND decodes overnight, best -24 and min -32…

Interesting that on 2200m minimum SNR capture was -32, while minimum SNR capture on 630m was -27 overnight (and 630m likely has the better IF receiver and sound card…).”

Hideo, JH3XCU, provided this link to an entry on the Japanese-language “472 kHz BBS” that displays a table of daily JA DX spots for the previous month.

Roger, VK4YB, reported that “QRN has been quite strong at times throughout the evening. I don’t know where this is coming from, because the radar is practically clear and propagation is weak.  VK activity is also down. I can’t remember the last time only 6 stations reported my signal in a session. One of those was WH2XCR. I saw a trace from WH2XXP a few times but only one decoded on both receivers.  I am unlikely to get reports from JA because that storm system is still active in the Sea of Japan…”

John, VK2XGJ, reported that today is the first day on Winter in the southern hemisphere and noise is ranging from S2 – S5 as sunset in his area is at 0645z.  He provided early reports for WH2XCR:

Ward, K7PO / WH2XXP, received reports from 29 unique stations including VK4YB and ZL2AFP.

This session began several days of relatively high storm potential overnight so my activity was limited.  I operated CW for about one hour before sunset when local storms were getting a little too close.  The exercise was another ground wave experiment and yielded some interesting results in the pre-sunset period which I will talk about in the future.  No additional QSO’s were completed.

On June 9 and 10, I will be conducting open discussion forums on the topic of MF and LF (specifically 137 and 472!) at Hamcom here in the DFW area.  It seems like this may be the last Hamcom before the bands open to amateurs so please attend if you can and provide some input or bring your questions.  Schedules are to be posted today on the above link.  There will be no daily report published on either of these days but if something “big” occurs on the air for either night, I will publish a special report with details.

Oceania 24-hour WSPR activity


Eden, ZF1EJ, provided reports for two WSPR stations and he received reports from seven unique stations.

Laurence, KL7L / WE2XPQ, provided reports for four WSPR stations and he received reports from three unique stations.  He shared two-way reports with WH2XCR.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, provided reports for VK5FQ and shared two-way reports with VK3HP, VK4YB, and WE2XPQ.  He received reports from VK2XGJ.  Merv’s DX report details can be viewed here.

WH2XCR 24-hour WSPR activity


Finally, Phil, VE3CIQ, submitted an item that is not related to 630-meters but is related to WSPR and since there is a significant amount of WSPR activity on 630-meters and Phil is involved with this project, I’ve decided to include it.  The Canadian coast guard is beginning an Arctic expedition and the details can be viewed here  (seriously, start by reading the link).  Phil adds that:

“…this is going to an interesting couple of months as this coast guard vessel heads up in to the high Arctic on it’s primary mission, but also with a wspr beacon attached to the ship.  We installed a QRP labs beacon, alternating on 20,30 and 40 meters. Call sign CG3EXP.  Ship is due to leave Toronto today”

The progress of the expedition is being reported graphically here.
