More of the same with another night of calm geomagnetic conditions and high noise in North America; Trans-Pacific openings improve significantly

– Posted in: 630 Meter Daily Reports, 630 Meters

The details for March 25, 2016 can be viewed here.

It was a noisy session in North America due to more storms in the central and Midwest regions of the US.  In fact, the lightning profile and strike count looks similar to the previous session.

12-hour North American lightning summary

 

Geomagnetic conditions were quiet for a second consecutive night, with periods of very quiet levels.  The Bz currently points to the North and solar wind velocities are down from the previous session, averaging near 450 km/s.  DST values continue to show stability although at negative levels very near the centerline.

 

 

 

Trans-Atlantic openings were down a bit during this session with only one European station reported in North America.  WD2XSH/17 received a handful of reports for stations in Europe but his numbers were down as well.  Report details can be viewed here.

DH5RAE -> N1BUG

WD2XSH/17 -> DK7FC/p, F1AFJ, G0LUJ, ON5TA, PA0O, PA0RDT, PA3ABK/2, PA7EY, PE1RKT

Joe, DF2JP, reported that his recent antenna work is showing 4 to 5 dB of improvement after deploying all four of the top loading wires.  He also reported this morning that he increased the vertical height another two meters to 17 meters tall and that leaves 6 meters of pole not deployed.  Hopefully he can continue to improve the system.  He notes that the loading coil at the top is higher than it has ever been.  Hopefully lightning won’t be a problem.

Paul, N1BUG / WI2XTC, reported that his QRN was at low to moderate levels in Maine.  He decoded fifteen WSPR stations including DH5RAE and WH2XGP.

Doug, K4LY / WH2XZO, reported moderate to high QRN during this session.  He decoded thirteen WSPR stations and was decoded by 37 unique stations.

Al, K2BLA / WI2XBV, reported high noise in Florida.  He decoded eleven WSPR stations and was decoded by 33 unique stations including WH2XCR.  Al indicates that only two of his decodes exceeded 4000 km.

Rick, W7RNB / WI2XJQ, reported improving band conditions.  He provided reports for seven WSPR stations and was decoded by 29 unique stations.  Rick’s unique report details can be viewed here.

Dave, N4DB, reported that he decoded thirteen WSPR stations with a station in DN07 as his best DX at a distance of  3489 km followed by reports from a station in DM33 at a distance of 3109km.

Mike, WA3TTS, reported, “No XCR decodes over night, but it appears I was WI2XJQ’s best rx dx overnight…”  Mike provided these statistics:

Ernie, KC4SIT / WI2XQU, submitted this lengthy report from the last week as he has been working to troubleshoot a unique problem:

“My transmission 10 day’s ago yielded to me being spotted by 40 unique stations, stretching from the east cost, to the Cayman’s, to Hawaii. Do not have a receive antenna as of this date so no report there. I was using one of John’s XKA boards and an Icom 7200. The signal was put into a variometer and into an improved inverted L (3 elements, 5 feet apart on the horizontal piece). For two days it was a great setup but on the 3rd day we experienced some type of board failure; it appeared that the board had been over driven (see photo). So our original board was sent to John XKA for repair.

During this time I become a listener on 630 again and throughout the past week or so my partner in this affair, David Day N1DAY, made 3 attempts to build a 630 transverter. All transmit attempts failed but his building efforts continue. Hopefully soon David, who’s 630 meter application is pending, will report success in the building of his own transverter.
Two days ago John XKA receives my original board and reports that the board was found to be in perfect working order and is on the way back to North Carolina. Now David and I are both stumped.
Then yesterday a board ordered by David from John XKA arrives. David also completes another build of his own board so we start yesterday’s session with 2 boards. Again, early into the session David’s board fails. However, I take the one he has received from John and it works flawless through the session resulting in a total of 20 “spot me” uniques.
I did do one thing different last night. We use the WSJT-X program for WSPR and we started the night with the power slider (bottom right of program screen) at 0 but were never spotted by any one. We continued to increase the power and were at the “8 mark” before we were heard. For 90% of the night we operated with the slider at max (10 mark) with no issues.
Doug XZO, who lives about 30 miles south and has visited with us twice offering technical advice, usually spots us with a +14 SNR gave us our best spot report for last night’s session; the report however was a SNR of 0 rather than the usual +14.
Still struggling with drift but we think we have a solution in that department.

Strange things are afoot at WI2XQU

WI2XQU session WSPR statistics

Trans-Pacific openings appeared to have been significantly better compared to the previous session.  Report details, excluding KL7 and KH6, can be viewed here.

Hideo, JH3XCU, posted links to two tables showing NA/VK -> JA DX totals and NA/VK -> JA peak S/N for the session.

Roger, VK4YB, reported, “Session began with very low noise. QRN built up later to modest levels. Propagation was much improved. N American decodes were plentiful in both directions with S/Ns in the low 20s.  VE6XH came storming back after missing yesterday. 160m 3 spots, best -19, 630m 24 spots, best -20, The Japan path was back also with many decodes and still more to come, I expect.” Roger received reports from JA1NQI, JA1PKG, JA3TVF, JE1JDL, TNUKJPM, VE6XH, VE7BDQ, W7IUV, and WI2XBQ.  He provided reports for WH2XXP and WH2XGP.

Phil, VK3ELV, received reports from TNUKJPM.  Late reports were received from JH3XCU and JA1NQI but those report details will be included in tomorrow’s report.

Joe, NU6O / WI2XBQ, provided reports for nine WSPR stations including VK4YB and was decoded by 21 unique stations including JA1NQI.

Ward, K7PO / WH2XXP, received reports from 54 unique stations including JA1NQI, JA3TVF, JH3XCU, VK4YB, and ZL2AFP.

Larry, W7IUV / WH2XGP, provided reports for nine WSPR stations and was decoded by 46 unique stations including JA1NQI, VK4YB, and ZL2AFP.  As W7IUV, Larry provided reports for nine WSPR stations including VK4YB.

This was a noisy session that left me lamenting that I should have missed more sleep this Winter to take advantage of quiet nights.  I’m really itching to work a few stations on CW but even with receive antennas it would not be very enjoyable at the moment.  WSPR activity was typical although my receive numbers were down.  Transmission numbers were normal but early evening S/N reports suggest that JT9 was likely going to be the mode of choice for a QSO.  I let WSPR ride for the night, however.  I received reports from WE2XPQ and shared two-way reports with  ZF1EJ and WH2XCR.  My WSPR transmission report details can be viewed here and my WSPR reception report details can be viewed here.
