OFF AIR for storms - just one more night - should be QRV Saturday night!

Good night of domestic propagation and some trans-Pacific openings with quiet geomagnetic and terrestrial weather conditions

– Posted in: 630 Meter Daily Reports, 630 Meters

In spite of a few storms in New Mexico it was a very quiet night  with high activity and good propagation, particularly on the transcontinental path and on to KH6 with John, W1TAG / WE2XGR/3 reporting first time decodes by WH2XCR.  There were significant numbers of false WSPR decodes and even a station reporting numerous multiple decodes on his otherwise clean signal, all of this usually indicating very quiet band conditions and good propagation (sometimes an errant noise blanker as well!).  The trans-Pacific path was present for higher power stations but seemed less robust than previous weeks and the path to Alaska was very good after several periods of poor post-storm conditions.


12-hour North American lightning summary


Geomagnetic conditions were quiet with a Bz at unity and solar wind velocities averaging 350 km/s, in the low category.  DST values are near unity but experienced a slight decrease over the past few reporting periods:







Trans-Pacific openings represent the bulk of the long-haul openings during this session, however, Roger, VK4YB, characterized the morning only as a “code-4” as he spent part of the evening on the “JA beam” before switching back Northeast.  The path to North America improved some as the morning progressed.  Roger submitted these statistics for the session:

“Rx 9*wg2xxm (-22) 1*wh2xgp (-29) 10*wh2xxp (-19) 6*wi2xbq (-21) 3*wh2xcr (-23)

Tx 1*w7iuv (-26) 3* we2epq (-28) 6* wh2xcr (-14) 1*jh1inm (-28)”

Joe, NU6O / WI2XBQ, had reports of multiple decodes of his signal at certain points during the early morning.  He indicates his signal looks clean.  What interesting is that some stations were observing the decodes while others were not so this could have been an instance of noise blankers and DSP generating the false harmonics or it could have been simple propagation as we have observed that before.  Joe was decoded by VK4YB and VK2XGJ:

Larry, W7IUV / WH2XGP, reports that this session was much like the previous with more activity in the East and limited VK openings.  He was decoded by 45 unique stations and decoded fourteen WSPR stations as WH2XGP using the eastern BOG.  Using the southwest receive antenna, he decoded thirteen WSPR stations as W7IUV including weak reports for VK4YB.  Larry also noted the excessive spurious signals overnight and also indicated that WH2XCR was very strong all night.

Phil, VE3CIQ, had a good night on the transcontinental path and at least one nice surprise.  He explains:

“This was a good session, seeing east west and north south , decoded 14, was decoded by 18, touching WH2XCR for one spot. “

Mal, G3KEV, reported his best WSPR DX reports of the session on the RSGB-LF reflector:  “SV8RV 2449km, IT9VPC 2173km, EB3FRN 1473km”

Doug, K4LY / WH2XZO, started the session only receiving due to high winds but he was able to transmit again near bedtime.  He submitted the following comments this morning:

“With quiet geomag condx, high latitude imp. Reported 9 and reported by 27 inc WD2XSH26 first time (this season or ever?).  Great reception- 15 unique decodes by VE7SL and WH2XGP where its still dark. Looks like 3 others with 14: WE2XGP/3, VE3CIQ, SWL/K9”

Regarding Doug’s recent receive antenna tests, he has these initial comments:

“Many of us try different receive antennas in an effort to hear the weak ones!

On 630M I have tried my 60M ladder line fed dipole, my Hygain Hytower, my 630M TX antenna, my 80M OCF dipole, an E-probe, and a Wellbrook ALA 1530LF loop.  After extensive A/B testing, the loop is usually better in its favored directions.  It’s bidirectional and has a good null 90 degrees to the plane of the loop which means if I favor northeast for Europe, I null the northwest.  I need to put a rotator under it.
The TX antenna provides the strongest signals and usually the strongest S/N except compared to the favored directions of the loop.  My E-probe picks up a lot of line noise which has been a local problem the past few months, and finally the power company has sent an employee to investigate, but he won’t let me show him the offending power poles (probably loose hardware) that I have spent hours identifying, first with a car radio and then a 2M yagi and FT-817.
The 60M dipole, 80M OCF dipole, and the Hygain Hytower are also OK on receive. As so many have written for 630M newcomers, use any antenna you have.  It may work quite well. Probably any 630M receive antenna I use on my 180′ by 200′ lot is compromised by the jungle of wires in the air and radials on the ground within 30′ of any receive antenna I use.
About 7 years ago I put up a Super Kaz antenna  and entered the National Radio Club medium wave winter contest.  The rules and scoring that year required reception of AM broadcast stations in the 530 to 1700 kHz broadcast band at 1000 miles distance or more.  Each station ID’d at 1000+ miles counted as one point.
I put up a 28′ high by 112′ long Super Kaz favoring south and was lucky enough to win the contest, mainly because I was just over 1000 miles from dozens of Cuban stations to my south.  I also used my 160M inverted L for other directions, but the Super Kaz was really super on those Cuban and other Latin American stations.  My main problem wasn’t hearing stations, but IDing the SS call signs!
This past week I put up my original K6SE 14′ by 28′ flag I built and tried out in Colorado 20 years ago.  It favors northeast and was almost as good as the loop in the loop’s favored direction.  I’m taking it down today and will be putting up a Super Kaz favoring northeast to see if I can improve upon the loop toward Europe.  To be continued!”
Rick, W7RNB / WI2XJQ, reports that he decoded 11 legitimate WSPR stations and was decoded by 28 unique stations:
Phil, VK3ELV, received a number of JA reports late during the previous session:

VK3ELV, as reported by 7L1RLL4

I don’t normally include content that is not directly related to 630-meters but Mike, WA3TTS, had a successful night receiving on 75 kHz and I hated to let it go to waste.  Comments can be viewed here and a map of his session can be viewed here.

I thought this was an outstanding session domestically with numerous CW-level reports.  Receiving was also better than it has been in some time, due in part to the diminished storm QRN.  My transmission reports can be viewed here and my reception reports can be viewed here.  With the start of the work week tomorrow, normal morning CW activity will return at 1000z.


WG2XIQ 24-hour WSPR activity


I did not take a census due to prior evening commitments but activity was very high once again.  WG2XKA noted that KC4SIT was new for this session.  Welcome aboard!

Eden, ZF1EJ, had another banner night with reports across North America including VE3CIQ.  I wonder when Eden will report another European?  It can’t be too far off.

Laurence, KL7L / WE2XPQ, experienced a significant improvement on transmit and receive including a few reports for VK4YB:

Merv, K9FD/KH6 / WH2XCR, experienced a remarkable session as well, reporting stations like VE3CIQ in Ontario, WE2XGR/3 in New England and WH2XZO in South Carolina.  He also decoded numerous VK’s and 7L1RLL in Japan in addition to receiving decodes from VK as well.
