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

Current Operating Frequency and Mode

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

Good propagation that was limited by noise in North America and Oceania that also seemed to deteriorate as the session progressed; Band activity was high, however; First time report of VK4YB at WI2XSV

The details for September 3, 2016 can be viewed here.

IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet. That includes stations using fake or pirated call signs. Please continue to be patient and let the FCC finish their processes. UPDATED: 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.

North America was largely storm free through the evening and overnight period, the exception being in my back yard where active storms in West Texas dominated the noise spectrum.  Isolated storms were also observed in the Desert Southwest  and Great Lakes region into Ontario during the evening and a few storms were observed in parts of the Midwest this morning.  Remnants of hurricane Harvey could be found off of the Atlantic coast and may have contributed to noise problems for stations in the Southeast through the mid-Atlantic region.  Mexico was a mess but this is their stormy time of year and one cannot discount the impact that those storms have on noise levels in North America.

11-hour North American lightning summary


Geomagnetic conditions remain at elevated-quiet levels although the A-index is currently registering 26.   The Bz is pointing slightly to the South and solar wind velocities are averaging near 510 km/s.  DST values remain at negative levels but the deep decreases have not been observed overnight and a general trend is toward the centerline.




David, N1DAY / WI2XUF, reported:

“Last night was a good night for 630m wspr activity here in the NC mountains.  Noise level settled down and I had 37 unique contacts – 9 RX, 28 TX. 

In doing my search of what other people are doing to interface their radios to antennas, I found that some are using transformers based on mix 77 ferrite cores while others are using mix 43.  I went back to mix 43 last night after a week of mix 77 use and performance seemed to improve.  But that could have been due to a change in propagation last night, so I am going to set up an A/B study to observe this for a while.

Doug, K4LY / WH2XZO, provided the following comments and statistics for the session:

“Storms  (remnants of Harvey) moved off coast reducing QRN a little as autumn-like high pressure began to dominate.  Thirty-one unique decodes of WH2XZO including five decodes by WH2XCR. The path to northwest to VE6 and VE7 only fair with VE6XH and WH2XGP hearing XZO.  Only 10 decoded from here.

We gave a 630M/2200M presentation yesterday at the Shelby, NC, ham fest using (with permission) the excellent Rudy N6LF/WD2XSH-20 power point presentation on the soon to be new bands (we hope!) 630M and 2200M-   http://www.antennasbyn6lf.com/2017/04/630m-2200m-talk.html

Good attendance . Among those present were  David, N1DAY/WI2XUF and Ernie KC4SIT/WI2XQU who contributed to the presentation.”

Dave, N4DB, reported that he decoded nine WSPR stations but he indicates that only WH2XXP was over a distance of 3000 km.  He also indicated that QRN remained high, in excess of RST 599, after local sunrise.

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 “The session was spoilt by heavy static from storms just over the border in NSW.  Other VKs were having difficulty also. We will have to wait for a clear night to see if we can pull in the East coast DX.  I’m pretty happy with the antennas now. The next cab off the block will be the W5EST special.”  Roger received reports from 7L1RLL4, CF7MM, JA1PKG, JA1PKG/2, JA3TVF, JH3XCU, KU7Z, TNUKJPM, VE6JY, VE6XH, VE7BDQ, VE7SL, W6SFH, W7IUV, WE2XPQ, WH2XGP and WI2XSV (first time report!).  He shared two-way reports with WH2XCR.

Ken, K5DNL / WG2XXM, reported that he decoded eleven WSPR stations and he received reports from 54 unique stations including VK4YB, WH2XCR, ZF1EJ and six Canadian stations.

Ward, K7PO / WH2XXP, received reports from sixty unique stations including ZL1EE, ZL2AFP, ZL2BCG, VK4YB and VK2XGJ.

Larry, W7IUV / WH2XGP, provided reports for sixteen WSPR stations and he received reports from 39 unique stations including WH2XGP.   As W7IUV, Larry provided reports for eleven WSPR stations including VK4YB.  Larry indicated that he would be using the backup transmit antenna until further notice as he makes repairs and improvements with the main transmit antenna.

It was noisy in Texas during the evening but I called CQ for a bit on 474.5 kHz CW starting before sunset and through the sunset period.  I completed no additional QSO’s and received no reports.  I transitioned to WSPR at 0246z after installing and configuring the new version 1.8 rc2 of WSJTx.  The upgrade did not go well because the .ini file from the previous version was not portable between versions.  This may not be a big deal to many but I have a number of configurations setup to speed up the transition between modes, call signs and sound devices that were lost.  After fixing those settings by manually re-entering (it was a beating!) , I operated WSPR for about an hour.  Hearing was difficult but the software did a nice job identifying and reporting stations and propagation was good as I was receiving quite a few reports at low power and relatively low duty cycle (1W-ERP at 25% transmit cycle).  This morning I opted to start WSPR again and operate through sunrise as I wanted to evaluate trans-Pacific openings.  Domestic propagation was very good but most trans-Pacific openings were limited to the points North of my station.  I should also note that receptions of stations to the West and Pacific Northwest did not begin in earnest until about 30 minutes before sunrise when I heard WH2XCR, WH2XGP, and WI2XJQ.  WH2XCR heard me earlier in my morning operating session but that path was not reciprocal at that time, either due to noise or propagation.  My primary storm source was off of the Atlantic coast and noise levels decreased significantly after those areas were in full sun.  I QRT’ed at 1212z, about 10 minutes after sunrise, with no Pacific openings to report beyond WH2XCR in KH6.  My WSPR transmission report details can be viewed here and my WSPR reception report details can be viewed here.

Eden, ZF1EJ, provided reports for five WSPR stations. He received reports from 29 unique stations  including WH2XCR.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, provided reports for five WSPR stations including VK4YB and he received reports from six unique stations.  He shared two-way reports with WH2XCR and WH2XGP.  Laurence indicated at 1251z that something did not look right about his transmitter / ATU / antenna metrics so he shut the exciter down while his receiver remained active.  At 1518z he reported that he was back on line again for a few minutes.    After a diagnostics review, Laurence reports that a 35-amp breaker has tripped so the system will remain off line until further notice.  DX report details can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, provided reports for fourteen WSPR stations including VK3HP and ZF1EJ. He shared two-way reports with VK4YB, ZL1EE and WE2XPQ. Merv received reports from 28 unique stations including VK2XGJ, ZL2BCG and ZL2AFP.  DX report details can be viewed here.
