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

Current Operating Frequency and Mode

OFF AIR; QRT Thursday night but back Friday morning by 1100z

Strong trans-Pacific path continues but very noisy during North American evening; WSPRNet maintenance outage 0100z – 0400z; 630-meter at CE0Y?; WH2XCR -> VK, JA1NQI-2, JH3XCU

– Posted in: 630 Meter Daily Reports, 630 Meters

Noise dominated the evening in North America as a very active storm system stretching from Mexico into western Oklahoma brought a large number of lightning strikes.  This morning the Plains states into the Midwest were impacted by storms but I found these morning storms to be much easier to null.


12-hour North American lightning summary


Geomagnetic activity  is quiet once again although a single reporting period during this session reached unsettled levels. The Bz has consistently pointed to the South and while solar wind velocities are averaging near 450 km/s this morning, a few reporting periods above 500 km/s were observed.







Had it not been for the noise, the WSPRnet outage from 0100z – 0400z might have been filled with JT9 or CW.  This morning yielded nice JT9 reports at both W5EST and WG2XSV, however, and levels were even promising for a QSO with WI2XFI as he was reporting my WSPR at -11 dB S/N.  It was just two weeks ago that I was speculating that if I can hit -15 dB S/N at Ken’s stations, his signal may be strong enough here for JT9.  We missed each other “on the fly” this morning but we will make it on another morning with similar propagation.  No CW sked this morning due to illness with the other station.

Neil indicates that his join.me screen sharing will likely be available around the clock in the near term and may transition to overnight only after a “breaking in” period.

The trans-Pacific path continues to be very good.  A number of stations were consistently decoded by the core VK stations and in many cases, two-way reports have been registered.

Ward, K7PO / WH2XXP, was reported at VK4YB this morning at audible levels with a report of -7 dB S/N.  He was decoded by 40 unique stations and reports that he almost remained QRT overnight due to storms during the day on Wednesday in order to dry out.

Larry, W7IUV / WH2XGP, reports that high latitude conditions were poor during this session.  He operated low transmit cycle in order to spend time listening for VK’s, where he received VK4YB once again.  Larry decoded seven WSPR stations and was decoded by 26 unique stations including VK4YB and VK5ABN.  With the flag pointing to the West, there were no East coast stations received.  Larry notes that his last spot from Roger came at 1338z, several minutes after sunrise in Washington state.

Roger, VK4YB, report that he had the following WSPR decodes for the session:  “14*WG2XXM (-20), 13*WH2XGP (-15), 44*WH2XXP (-7), 5*WD2XSH/20 (-26), 47*WH2XCR (-8).   Roger was decoded by WH2XGP, VA7MM, WD2XSH/20,  N6SKM, and  WH2XCR.  Previously unreported WSPR details for Roger follow:

Neil, W0YSE/7 / WG2XSV, submitted the following report:


Ken, SWL/K9, in Indiana was listening with an indoor antenna and had a very nice session in spite of WSPRnet struggles:

“Well, the weather guessers faked me out again last night. No T-storms, just some rain, so theoretically I could have left the outside antenna hooked up. You know how it goes though… can’t take chances.

So, the entire session was on the ferrite rod(s) antenna. WSPRnet is a mess. Didn’t show that I had any spots from /20. I actually had 5. I tried to manually upload the 5 but it will only take one for some odd reason. I’m not even going to bother checking everything else it missed.

Here’s the map of my last night’s session. Btw, this session was logged with the just the antenna… without the use of any preamplification, just the antenna straight into the sdr.

Surprised I was able to decode the West considering how noisy the band was last night.”

I thought this was a very interesting opportunity posted by Alex, LU8YD, on the RSGB LF reflector:

“From september 26 to september 30  some LU amateur radio an LF MF DXers will be operating in CE0Y.  Hamradio from 80 to 6 meter maybe 160 meter. TX RX.  VLF LF MF listening with  R-75 and Perseus SDR recording WAVs from 100 KHz to 1710 KHz at night times .  Not grabber online.  Maybe: Notebook+SpectrumLab with antenna via Mic in for VLF.  Antennas: Loops and  Beverages 200-600 meter long to…. ??? meter long. maybe Kite antennas.  If you are  interested in TX ( 136 KHz -472 KHz ) to Easter Island in this week please write to me only via: lu8ydnqn@gmail.com

There was a single “new” receive stations observed, W5ADD, located in Louisiana.  Its possible he was active last season.  Welcome aboard!

There were no reports from the trans-African, trans-Atlantic, or trans-Equatorial (NA/SA) paths.

Eden, ZF1EJ, reported stations in the southern half of the US during this session:

Laurence, KL7L / WE2XPQ, reports that some type of an audio problem has occurred at the stations and he will have to address later.  He was able to decode WH2XCR at one point during this session before the problem began:

Merv, K9FD/KH6 / WH2XCR, continues to decode stations, including VK4YB, WD2XSH/20, WH2XGP, and WH2XXP, while the receive dipole lays on the ground.  He was decoded by a full compliment of VK’s in addition to JA1NQI-2.  JH3XCU’s report was initially missed but Merv informed me and the decode data has been amended below:

“How should we evaluate transpacific (TP) 630m propagation conditions compared to year ago?  Better propagation conditions increase the number of spots, and so does good ol’ intensive station activity.  How do we tease these factors apart?

Are there other factors too, like less storm activity making less noise perhaps?  Stations using higher transmit percentages TxPct for WSPR? Stations re-positioning antennas for more effective VK-N.Am. transmissions and receptions both ways?  Stations using more TX power and/or better receivers and/or reducing local noise?  I leave those latter questions to you.

Plainly, there’s lots more station activity.  TABLE 1 and TABLE 2 here disclose 155 decodes and itemize the counts between N.Am. and VK from yesterday’s blog as just one day’s instance from this blossoming TP season. Last season never registered more than about 28 such decodes on even the best nights!  The Tables themselves tell us that more TX stations and more RX stations jointly mean many more decodes.  It’s not as simple as being proportional to rows times columns, though.

Is 630m TP propagation better this year? We’ll see.  One year ago, a banner night Aug. 15, 2015, yielded these spot counts:

6 XGP-vk2xgj, 2 XGP-vk3elv,

11 XND-vk2xgj, 1 XND-vk3elv, 5 XND-vk2ddi.

XGP yesterday did 7 XGP-vk2xgj compared to 6 last year. XXP yesterday is listed with 10 watts, same as XND a year ago. XND yesterday got 28 decodes at vk2xgj vs. 11 decodes XND-vk2xgj a year ago.

Today’s takeaway? 630m TP propagation is about the same, maybe a little better.  But, wow, what a difference more activity by 630m station operators makes!”
