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

Current Operating Frequency and Mode

OFF AIR but hope to be back by 1115z Saturday morning if I don't oversleep

Night one of opening weekend on 630-meters for many lucky operators which just happened to coincide with high QRN and a G2 geomagnetic storm; Many CW and digital QSO’s completed under part-97 rules; Relatively good trans-Pacific openings including WH2XXP -> JA1NQI/2, JA1PKG, JE1JDL; W1TAG/1 reports Europeans on WSPR; W5EST presents: ”Trans-Pacific Northeast Path Trios”

– Posted in: 630 Meter Daily Reports, 630 Meters

The details for October 14, 2016 can be viewed here.

The UTC amateur registration database is here.  

HERE are a  few mode specific comments addressing where modes are located now and probably where they are best placed in the future

Blog administrative note:  As we transition to amateur activity on 630-meters, more of my focus in this blog will be on two-way QSO highlights.  I have not yet decided how this transition will impact WSPR reports long term but I will more than likely begin including WSPR summaries rather than specific operator details for WSPR reports.  The next few weeks will help me make that decision.  Thanks for your patience as I make adjustments.

Wow – what a whirlwind night.  The release of a portion of operators in the US to use MF and LF caught many of us by surprise as most of us were resolved to ride out the 30-day waiting period and be on the air on Sunday night as amateurs (rather than experimental stations).  That will be the case for many but whenever opening night is for an individual station, it will be one to remember.  My opening night was noisy and geomagnetic conditions were very active resulting in challenging propagation.  QSO’s were completed in spite of the difficulties and it just goes to show the level of tenacity that many of these operators possess.

It was unfortunate that it was so noisy during this session as new stations enter the band for the first time but storms in the central US into the Midwest made listening tough, even with directional antennas.  West Texas into Mexico offered challenges during the evening hours and storms in the Caribbean made QSO’s with ZF1EJ difficult at times.  Many stations reported high QRN.

Geomagnetic conditions are now at G2 storm levels as the Kp reach 6.  Some relief may be on the horizon according to Solarham as a geoeffective coronal hole becomes less so.  The Bz is pointing to the North this morning with solar wind velocities peaking well over 700 km/s during the evening with a current average near 690 km/s.   DST values suggest disturbed band condition and clearly reports favored North / South paths over East / West.  It’s a mixed bag and sometimes the opposite is true.  Sunrise peaks were prolific during this session on the path to the North.

 

 

 

To characterize the extent of profoundly disturbed band conditions, Laurence, KL7L, submitted the following image from 0700z of Aurora at his QTH:

Roelof, PA0RDT, reported of VO1NA’s QRSS transmissions, “The sun keeps playing havoc, the west to east path is heavily effected as is the  path from the north. However, on 518 kHz, NAVTEX Penang, Malesia, over 10k km was received yesterday evening at 20:14 UTC.”

Reverse beacon network reports for the session follow:

 

CW is a cornerstone activity on 630-meters and many QSO’s were completed during this session with some specific details reported later in this presentation.  The following list of operators represents just a few CW QSO’s completed during the session:

K9SLQ and K9MRI

K4LY and N4PY

K4LY and KB5NJD

NO3M and KB5NJD

With many amateurs activating for the first time on 630-meter, this session had quite a bit of digital mode activity.  What follows are a number of screen captures, captions speaking for themselves, of some digital activity during the evening.  This is by no means complete but should represent a reasonable cross section of activity.

Eric, NO3M, noted that he completed three FT8 QSO with K9MRI, K9SLQ and K4LY,  one JT9 QSO with ZF1EJ, and one CW QSO with me, KB5NJD.  Eric added that  “…XSB in Stowe heard below the band. XSH/31 nice sigs.”

Trans-Atlantic WSPR report details can be viewed here.

John, W1TAG/1, provided reports for G1VAG and DH5RAE.

Hugh, M0DSV, reported astonishment at the amount of band activity including decodes of G3XBM’s 10 mW WSPR signal.  Hugh posted these comments on the RSGB-LF reflector:

“I captured a phalanx of WSPR stations, quite a bewildering number. Is it always like this at weekends? My best was EB8ARZ (and I had a DC8ALR supposedly 2771km away south of Greenland which I ignored).”

John, WA3ETD, reported that “WA3ETD was caught unprepared for the band “opening” Friday instead of Sunday…I was tied down to social events that proved impossible to escape.  Operation was on WSPR for the session, which was just average considering the date.  WA3ETD heard 13 and was spotted by 38, with zero activity in the far west and PNW. Best DX was VE6JY.  CU on other modes this weekend!”

David, N1DAY, reported that he has been”…making antenna improvements which paid off in a new record for me last night.  52 unique spots – 39 TX, 13 RX.  13 of the TX were >1000KM. I  took the parallel horizontal elements of my Marconi Tee and spread them out in bow tie fashion.  This resulted in a significant reduction in required inductance on the resonator coil (a good thing).  Like most others, I got my PLC approval yesterday.”

Ken, K5DNL, reported that he  decoded thirteen WSPR stations and he received reports from 55 unique stations including eight Canadian stations.  He shared two-way WSPR reports with WH2XCR and he completed two-way FT8 QSO’s with KB5NJD and two-way JT9 QSO’s with NO3M, ZF1EJ and KB5NJD.

Doug, K4LY, reported that “limited WSPR activity resulted in decoding 11 and being decoded by 46 with moderate QRN and rather poor ionospheric conditions. Made 7 contacts using three modes.”  Doug also noted reports of his CW from Ralph, W0RPK.  Doug submitted this account of the last 24-hours from his perspective:

“What a surprise.  I got up from my afternoon nap and checked the ON4KST Chat page and saw the news!  Was I one of the ones with my PLC Amateur Radio Application approved?   I went to my email with fear and trembling because I am slightly less than 1000 meters from a HV power lines.  Whoopee, I was approved!

I emailed our locals and asked David, N1DAY, if he could get on 630M FT8.  We made a contact a little later at 2221.  Then a  near my SS, I was surprised to get a call from Carl, N4PY, in NC on CW.  You NC guys rock!  Have worked 3 of you on 630M!

At 0000, Joe, K9MRI, and I completed an FT8 contact., and then another FT8 contact with Eric, NO3M, at 0135.

Moving to JT9, Darrell, K9SLQ, and I contacted at 0154, and my best DX for the night was Eden, ZF1EJ,, at 0218.  This morning I got up and band was still noisy, but John, KB5NJD, and I managed a CW contact with signals peaking 559.  A number of others reported K4LY on the PSK Reporter, and on WSPR where I decoded 11 and was decoded by 46.

I was a little unprepared for and clumsy at all the shifting between modes.  Also, after no problems for almost a year my Monitor Sensors transverter kept shutting off when I ran more than 50 watts reporting  “RF detected on input. Signal is bypassed.” The transverter was not hot at all, and it was running into a 1.15:1 SWR.   I plan to rework the coax and 15V wiring today to see if I can overcome the problem.

Think the approval came as surprise to everyone who were expecting it to be Sunday night.  Bet others will be scrambling this weekend to get on the air, and I look forward to many more Qs tonight and Sunday with hopefully better conditions.  Thanks for the contacts…”

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

Al, K2BLA, indicated that he was only listening with WSPR this morning.   He added that “I need to re-educate myself for JT9 and hope to be on tonight. WSPR: hrd 13 incl VK4YB and 2 way with XCR HB 34 one CW @ 579 moderate noise this AM”

Ken, SWL/EN61 (SWL/K9), reporting from Indiana, indicated that W8RUT was at -22 dB S/N this morning just prior to 1400z.

Robert, KR7O, indicated that “WH2XXP copied all night, best -11, WI2XBQ copied a few times best -27 WSPR…first monitoring session. Indoor Ukrainian mini-whip.”

Mike, WA3TTS, reported that he decoded seventeen WSPR stations overnight, including best DX for the session, “…XCR, XXP, ZF1EJ on NE EWE early SW EWE late.”  He also submitted this capture during the afternoon of K9SLQ’s first WSPR activity:

Dave, N4DB, reported that he decoded fourteen WSPR stations.  Dave also noted a number of other digital and CW signals during the session.

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, received reports from CF7MM, JA1NQI/2, K2BLA, K7NDE, VA7JX, VE6JY, VE6XH, VE7BDQ, VE7CA, VE7CNF and WE2XPQ. He shared two-way reports with WH2XCR and WI2XBQ.

John, VK2XGJ, is excited about the potential of seeing US amateur call signs in his list but submitted this capture that shows WH2XXP:

It was a strong session in spite of poor band conditions and propagation.  The fact that it was opening night strengthened the resolve of many, myself included.  I began calling CW during the afternoon after my approval arrived, not expecting much. I was really staking out the bottom of the band.  There were a number of unidentified signals that showed up on the band on ground wave, however, and I received a report of my CQ’s during the evening from Steve, KT5H, located in central Arkansas.  My first QSO under Part-97 rules was with K5DNL on JT9 (images shown earlier).  Ken and I went on to complete a QSO on FT8 a bit later (also detailed earlier).  During the late evening the band was sufficiently poor that I struggled to work ZF1EJ but we completed a QSO this morning on JT9.

One of the other highlights of the session was working NO3M and K4LY on CW.  With a poor eastern path, Doug was a challenge in South Carolina but Eric was as loud as I have ever heard him, RST 599 through most of the QSO.  Here is a brief recording of Eric from the “middle frame” of our QSO this morning as I was listening to the East:

Eric also recorded me calling CQ this morning following our QSO as the sun rose in Pennsylvania:

 

The morning was much better than the evening but it was all fun.   Al, K2BLA, reported my CW at RST 589 but he has some work to do before he can transmit CW from what I understand.   Dave, N4DB, reported me at RST 439 while I was working Doug and Eric.   I QRT’ed early, just prior to first light, due to too many things happening in my household.

Regional and continental WSPR breakdowns follow:

North American 24-hour WSPR activity

 

South American 24-hour WSPR activity

 

Asiatic Russian 24-hour WSPR activity

 

Japanese 24-hour WSPR activity

 

Oceania 24-hour WSPR activity

 

Eden, ZF1EJ, was very active during the evening operating session using JT modes and looking for QSO’s.  At some point during the previous 24-hours, Eden provided reports for K4LY and he received reports from sixteen unique stations.  Look for Eden to be active on a number of QSO modes very soon!

ZF1EJ 24-hour WSPR activity

 

Laurence, KL7L / WE2XPQ, turned a tough night into a strong effort, provided reports for three WSPR stations including VK4YB and he received reports from two unique stations. He shared two-way reports with WH2XCR.  Laurence added that “Au over night but waterpath still providing sigs – XXP decoded a few -times – something odd on the wave angle I rx him…In Anchorage K indices spiked at 7 overnight, back at 3 now. Hopefully the geoeffective Coronal winds stop blowing soon as its topping up the nasty stuff reservoir…”DX report details can be viewed here.

WE2XPQ 24-hour WSPR activity

 

Kevin, KL7KY, provided reprots for two WSPR station including WH2XCR.

KL7KY 24-hour WSPR activity

Jim, W5EST, presents, “TRANS-PACIFIC (TP) NORTHEAST PATH TRIOS”:

 

“Today’s illustration provides 630m TP northeast (NE) path information from fifteen (15) VK4YB–N.America path trios. As you recall, a recent blog post prepared graphs for the southwest (SW) TP direction involving 37 trios of peak SNRs from the 36-night interval 9/1 – 10/6 /2017.   http://njdtechnologies.net/101117/ .  Today’s three graphs are scaled as similarly as possible to those blogged Oct. 11.  The trio concept is discussed at: http://njdtechnologies.net/092917/ .

Today’s left hand graph shows a 20 dB range of peak SNRs on the NE TP path, similar to the SW TP path.  A slight upward peak SNR trend with NE TP distance is without significance, considering the 20dB range of peak SNR variability.  All the graphed transmissions emanated from VK4YB, the VK station closest to N. America that provided all the NE trios.

Now please look at the center graph and right-hand graph. Today’s results for the TP NE path Loss Difference Ratio and path difference dB’s look no different from a sample of 15 points from the SW path results.  By that, I mean a sample plotted versus similar Distance Ratios under 2.0.  However, reasonable minds could differ since the trend of the NE 15 points is downward. I think the variability both below and above zero dB in the right hand graph telltale demonstrates no significant trend.  Let’s await further VK/ZL-N.America successes to inform us more.

This trans-Pacific 630m NE propagation study could not happen without persistent station operations by the many stations in the 630m community. Thanks in this case go to all 630m VK transmitting stations within one hop of the ocean east of Australia, to WH2XCR on Molokai, and to receptions by W/VE stations within one hop of the west coast of N. America.   For the NE TP path, I’ve listed the N.America receivers/stations forming at least one NE TP trio via VK4YB-WH2XCR:

        VE6JY, VE6XH, CF7MM, VE7BDQ, VE7SL,

        WE2XPQ, WD2XSH/20, WG2XSV, WH2XGP (3 rx’s: wh2xgp, w7iuv, w7iuv/w),

        WI2XBQ, KK6EEW, N6SKM, WW6D, WG2XXM.

The 16th trio point involving WG2XXM was not graphed. That’s because the combination of peak XCR-xxm SNR -18dB versus VK4YB-xxm SNR -21dB led to a widely outlying Loss Difference Ratio value of 2.5. Probably a truly representative peak SNR for the XCR-xxm path did not get through on the few nights from which that peak SNR was sought.

The following VK stations transmitted and were decoded in Hawaii but not in N. America, so did not form data points on today’s graphs. Their peak decodes at WH2XCR are listed here:

TU & GL on 630m!”
