Very high noise for the eastern half of North America; Quieter geomagnetic conditions with significant improvement for trans-Pacific paths but fewer trans-Atlantic openings reported; More JT9 QSO attempts between VK4YB and JR1IZM

The summary for February 8, 2016 can be viewed here.

Unlike the previous session where the noise started to be a problem overnight, it was noisy before it was dark here in Texas during this session as storms in the Midwest  and Southeast progressed and expanded as they moved out to sea.  It’s all a preview of what to expect this Spring and Summer.

12-hour North American lightning summary

 

Geomagnetic conditions were quiet through the session.  The Bz was variable but is currently pointing slightly to the South.  Solar wind velocities were elevated for a few periods but have returned to moderate levels, averaging 450 km/s.  DST values have moderated significantly with both the Kyoto and Australian indicators showing slight variability close to the center line.

 

 

 

Trans-Atlantic openings were tempered once again although when the weather and noise conditions are considered in the East and Northeast, it seems likely that propagation was actually better than the results suggest and weak signals were only masked by noise.  At least a couple of transmitting stations are off air or operating at reduced power due to ice.  Report details for the following trans-Atlantic decodes can be viewed here.

G3KEV –> WD2XSH/17

G8HUH –> WD2XSH/17

WG2XXM –> LA2XPA, LA2XPA/2

WD2XSH/17 –> F59706, G0LRD, G3XKR, G8HUH, LA2XPA, LA2XPA/2, OR7T, PA0O, PA0RDT, PA7EY, PE1OPK/RX2, PE1RKT

Doug, K4LY / WH2XZO, reported that he decoded only seven  WSPR stations, receiving reports from  44 unique stations. Doug added that “moderate rain shut down transmitting for two hours last evening, but it was mainly the QRN that limited reception all night.”

Rick, W7RNB / WI2XJQ, reports that the session was less than optimal with no reports East of the Mississippi.  I’m sure those missing reports were the result of the high noise level in the East.  Rick provided reports for ten WSPR stations and was decoded by 24 unique stations.  His unique report details can be viewed here.

Paul, N1BUG, indicates  that he had a very high QRN level in Maine, reporting eight WSPR stations overnight.

Toby. VE7CNF, reported that VE7VV was transmitting for the first time overnight and is a new station in British Columbia.

Trans-Pacific WSPR openings were much better during this session.  John, VK2XGJ, reported, “…must be good condx as I have printed WH2XCR approx 26 minutes after local sunset.   WH2XXP as well at 32 minutes after local sunset.”  Its been a while since we have observed early reports across the Pacific.  Trans-Pacific report details, excluding KL7 and KH6, can be viewed here.

Roger, VK4YB, reported that QRN was down a bit for this session which helped with a number of openings.  Roger provided reports for WG2XIQ, WG2XXM, WH2XGP, and WH2XXP.  He received reports from 7L1RLL4, JA1PKG, JA3TVF, JE1JDL, JH1INM, JH3XCU, JR1IZM, N6SKM, TNUKJPM, VE6XH, W1CK, and WH2XGP.  Roger added that, “Session started with low base noise and no QRN. WH2XGP,WH2XXP, WG2XXM, and WH2XCR were decoded while it was still light. Then the storms in the coral sea started to spark-up.  Nevertheless a good number of reports were given. Later QRN got worse and another JT9 QSO [attempt] with JR1IZM was unsuccessful, although JA3TVF managed to decode both parties.  All in all a fantastic session with a record breaking 25 stations decoding VK4YB. The WSPR Map label needed 4 lines to fill in the callsigns, a rare occurrence in this part of the world.”

Kiyo, JR1IZM and Roger, VK4YB, made another JT9 QSO attempt after Roger returned his JA antenna to operation.  At 1216z both stations transitioned to JT9 after Kiyo received Roger using WSPR.  Unfortunately band conditions were not good enough during this session to complete a two-way QSO although Hideo, JH3XCU, reported on the ON4KST chat and on the teacup bbs that JA3TVF had received Roger so the signal is making the long haul to JA.  Good luck to both stations as they work toward this first time accomplishment!

Phil, VK3ELV, received reports from TNUKJPM.

Ken, K5DNL / WG2XXM, reported that he decoded seven WSPR stations including WH2XCR and ZF1EJ.  He was decoded by seventy unique stations including VK4YB, LA2XPA, LA2XPA/2, WE2XPQ, WH2XCR, and ZF1EJ.

Ward, K7PO / WH2XXP, received reports from 68 unique stations including VK4YB, VK2XGJ, and ZL2BCG.

Larry, W7IUV / WH2XGP, provided reports to 38 WSPR stations and received reports from twelve unique stations including ZL2BCG.  Larry shared two-way reports with VK4YB.

With the high noise level and an amplifier project that is diverting much of my evening attention I began transmitting WSPR at 2302z.  It was noisy from the start and never improved but domestic openings seemed very good  and I was pleased to receive reports from VK4YB which typically indicates that propagation is very good.  My WSPR transmission report details can be viewed here and my WSPR reception details can be viewed here.

Eden, ZF1EJ, provided reports for six WSPR stations and received reports from 29 unique stations including two-way reports with WH2XCR.

ZF1EJ 24-hour WSPR activity

 

Laurence, KL7L / WE2XPQ, shared two-way reports with VK4YB and WH2XCR, and received reports from 7L1RLL4, JA1NQI, JA1PKG, JA3TVF, JA8SCD5, JE1JDL, JH1INM, JH3XCU, JR1IZM, and TNUKJPM.  DX report details for these stations can be viewed here.

WE2XPQ 24-hour WSPR activity

 

Merv, K9FD/KH6 / WH2XCR, continues to see improvements and very good propagation in and around the Pacific, with two-way reports shared with ZF1EJ, WE2XPQ, VK3ELV, and VK4TB.  He received reports from VK2XGJ, ZL2BCG, 7l1rll4, JA1NQI, JA1PKG, JA3TVF, JE1JDL, JH1INM, JH3XCU, and JR1IZM.  Mainland North American reports were fragmented once again due to noise in the East but Merv’s coverage continues to be very good.  DX report details can be viewed here.
