Radio: it's not just a hobby, it's a way of life

Current Operating Frequency and Mode

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

Good domestic propagation but noisy for North America, particularly in the East; Trans-Pacific openings down a bit but still present; VK4YB returns to air after yesterday’s lightning strike; Good paths to JA from KH6 and VK; VO1NA CW on 477.7 kHz audible at PA0RDT

The UTC amateur registration database is hereEven if you don’t think you will use these bands, REGISTER!  Doing so prevents UTC from future PLC coordination in these bands near your QTH.  While amateur interference to PLC systems is a myth and PLC systems are migrating away from RF, there is no reason to give them a reason to do something weird in the future.

A wide arc of storms was active across the central US into Canada with stations on the East coast reporting high noise this morning.  A few storms were reported during the evening in the Southeast and an active cluster persists in the Gulf into the Caribbean this morning.  The “Four Corners” region into eastern New Mexico also experienced storms that continue this morning but even listening that direction from my station in North Texas this morning, I am not sure that the noise is as bad as the map below represents.  I’m sure its a problem in New Mexico and the region as a whole, however.

11-hour North American lightning summary


Geomagnetic conditions were quiet through this session. The Bz is pointing slightly to the South this morning, however.  Solar wind velocities remain low, averaging near 385 km/s.  DST values are much like the previous session although the Australian values have come off their highs in positive territory while the Kyoto measurement continues to meander “just South” of the center line at negative levels.  Propagation seemed to be pretty good through this session, at least for North America.




Paul, W0RW / WA2XRM, reported the return of this interference source in his local area on the 600-meter research group email list in this posting:

“The Pueblo CO  HADGPS  has returned to the air.   I thought it was a new CFL in the neighborhood.  Fairly strong in COS.  They are on 458 kHz but now running at least 1000 pps.  The data pulses can be heard from 410 to 480 kHz.
I am sure it can be nulled out with a loop.  It is possible to achieve 1/10 meter accuracy using HSDGPS.  See <http://www.ursanav.com/solutions/technology/dgps/>.  You might be able to hear it at night if you tune to 458.  I can hear it all the time on ground wave.  Welcome to the new Loran.”

Roelof, PA0RDT, reported that Joe, VO1NA, was audible on 477.7 kHz CW again this morning.  He provided the following screen capture and recording:

Neil, W0YSE/7 / WG2XSV, indicates that he was operating in a receive-only capacity overnight, providing reports for eight WSPR stations including WH2XCR and WE2XPQ.  He also reports that he decoded JT9 from VE7BDQ once at  -11 dB S/N at 0542z.

John, WA3ETD / WG2XKA, reported that he decoded nine WSPR stations and he was decoded by twenty.  John indicates that band conditions have been flat in Vermont for the last two weeks and record heat will only exacerbate noise conditions.

Doug, K4LY / WH2XZO, reported “Good activity, but QRN limited results to same as previous night- 9 decoded and 37 decoding XZO.”

Rick, W7RNB / WI2XJQ, provided reports for eight WSPR stations and he received reports from twenty unique stations.  Rick’s unique report details can be viewed here.

Mike, WA3TTS, reported that he decoded ten WSPR stations overnight with a S6 noise baseline.  His session best reports were WH2XXP at -20 dB S/N at 1100 UTC and  ZF1EJ at -22 dB S/N at 0432 UTC.  Mike added that this session was “Worse than prior evening by several dB.”  He also noted that he “Hrd 7 on 630m with e-probe and Heath VLF converter on 630m…”

Dave, N4DB, indicates that QRN was very high but propagation was good.  He reported that he decoded eleven WSPR stations in Virginia.

Trans-Pacific report details, excluding KL7 and KH6, can be viewed here.

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, indicates that his lightning strike appears to be localized to a computer and no radio gear was damaged, which is remarkable.  He added that “Noise is reasonably low, propagation is down somewhat and confined mainly to the PNW. Heard 11, heard by 36.”  Roger received reports from CF7MM, JA1NQI, JA3TVF, KJ6MKI, KR6LA, N1VF, N6GN, N6SKM, TNUKJPM, VE7BDQ, W6SFH, W7IUV, WE2XPQ and WW6D.  He shared two-way reports with WH2XCR, WH2XGP and WI2XBQ.

Joe, NU6O / WI2XBQ, provided reports for eight WSPR stations and he received reports from twenty unique stations including VK2XGJ.  He shared two-way reports with VK4YB.

Ken, K5DNL / WG2XXM, provided reports for ten WSPR stations and he received reports from 66 unique stations including VK4YB, VK2XGJ, ZL2AFP and six Canadian stations.  He shared two-way reports with WH2XCR and ZF1EJ.

Ward, K7PO / WH2XXP, received reports from 56 unique stations including VK4YB and VK2XGJ.

Larry, W7IUV / WH2XGP, provided reports for eleven WSPR stations and he received reports from 37 unique stations including VK2XGJ.  He shared two-way reports with VK4YB.   As W7IUV, Larry provided reports for twelve WSPR stations including VK4YB.  Larry added that “Condx seem OK but not great up here. Not sure at this point how much is due to prop and how much due to antenna work ongoing.”

My session began at 0017z with CW on 474.5 kHz as I called CQ through the evening.  The band sounded pretty good in spite of high noise while listening omni.  I transitioned to WSPR for about 40 minutes starting at 0200z which translated to three transmissions at 21% duty cycle and between 1 and 2-watts ERP.  Again the band sounded open but storm noise made omni listening difficult.  Using receive antennas on WSPR often leaves stations not reported which is a complication in the central US with active coasts on either side.  I QRT’ed for the night at 0240z.  My WSPR transmission report details can be found here and my WSPR reception report details can be found here.

WG2XIQ 40-minute WSPR activity


I returned to air this morning, CQing on 474.5 kHz, and received a nice report from Ralph, W0RPK, in eastern North Carolina.  He reported “…Almost workable in TS QRN…DIY E-Probe and Drake SPR-4.”  He provided the following screen capture:

I continued to call until a few minutes before sunrise when the noise character changed sufficiently to let me know the session was likely done.

Band activity was very high for the first night of Fall.  Phil, VE3CIQ, noted that there were approximately 120 MF WSPR stations active during the evening in North America.  Regional and continental WSPR breakdowns follow:

North American 24-hour WSPR activity


European 24-hour WSPR activity


Japanese 24-hour WSPR activity


Oceania 24-hour WSPR activity


Eden, ZF1EJ, provided reports for four WSPR stations. He received reports from 23 unique stations including WH2XCR.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, provided reports for six WSPR stations including VK4YB and he received reports from fourteen unique stations. He shared two-way reports with VE7BDQ, WH2XCR, WI2XBQ, and WI2XJQ.  DX report details can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, provided reports for twelve WSPR stations including VK3HP and ZF1EJ. He shared two-way reports with VK1DSH, VK4YB, ZL1EE and WE2XPQ. Merv received reports from 36 unique stations including JA1NQI/2, JA1PKG/2, JA3TVF, JE1JDL, TNUKJPM, VK2EIK, VK2XGJ, VK3ALZ, VK3DB, VK3WRE, VK5ABN, VK5AKK, VK7TW and  ZL4EI.  DX report details can be viewed here.
