The details for February 17, 2017 can be viewed here.
QRN levels in North America were much improved during this session although a few “flare-ups” in the Gulf of Mexico appeared by morning. Propagation was pretty good with nice trans-Atlantic openings and strong domestic coverage as unsettled geomagnetic conditions returned. High QRN was reported in Australia by VK4YB, impacting inbound signals. Outbound trans-Pacific signals were fair with good reports from stations in Alberta Canada.
Geomagnetic conditions returned to unsettled levels overnight. The Bz was pointing to the North for much of the overnight period although a number of short-lived periods of southerly Bz were also observed, particularly this morning. Solar wind velocities were elevated above 400 km/s through the overnight session, with periods above 500 km/s. The current average velocity is near 485 km/s. DST values were erratic during the evening and the ‘bottom dropped out’ overnight with significant decreases for both indicators presented below.
There really is other life on 630-meters besides WSPR: Neil, W0YSE/7 / WG2XSV, and Rick, W7RNB / WI2XJQ, had a CW QSO during the late evening on 474.9 kHz. Neil indicates that he reported Rick at RST 549 and Rick reported Neil at RST 449. The QSO occurred between 0549Z and 0552z. Congrats guys – thats what it’s all about!
Trans-Atlantic WSPR reports were numerous and generally concentrated in New England. I think most of these reports occurred just prior to the onset of unsettled conditions. Report details can be viewed here.

John, WA3ETD / WG2XKA, reported that he heard seventeen WSPR stations and was heard by 55 unique stations, including XE2EJ, LA2XPA/2, PA0O, G8HUH, OR7T, F59706, and PA0RDT. John operated WSPR-15 during the afternoon, receiving reports from N1BUG in Maine and WH2XZO in South Carolina (not uploaded!). He transitioned to WSPR-2 at 0000z.
Doug, K4LY / WH2XZO, reported that his QRN level was reduced, allowing him to decode thirteen WSPR stations and receive decodes from 51 unique stations. Doug reports that his best DX was two-way reports with WH2XCR. Doug also operated WSPR-15 during the afternoon, indicating no reports for WD2XSH/15. He did decode WG2XKA but no report was uploaded. He was transmitting for part of the afternoon, returning to WSPR-2 by dark.
Ken, K5DNL / WG2XXM, reported that he decoded thirteen WSPR stations and received decodes from 67 unique stations, including F1AFJ, KL7L/M, WE2XPQ, WH2XCR (two-way), ZF1EJ, and XE2EJ.
Rick, W7RNB / WI2XJQ, had an exciting session! He explains:
“What a night — !!!! My Evening started out with a CW QSO with WG2XSV 449, 549, then back to wspr — with a very noisy band. Thought it would be a bust, really. Then this morning I go to turn off the station and find that the WSPR computer had reset, due to an update, so figure that no stations were logged.This morning, I look at my log and find that power had been off for several hours instead, but I had 37 stations, 9 heard and 28 unique station heard me, covering the whole US and the BaHa — XE2EJ!! And several new ones to boot. Surprise!!!”
Mike, WA3TTS, reported, “Conditions down from the night before, but XCR still making it to EN90. Best search by distance result…”
Trans-Pacific report details, excluding KH6 and KL7, can be viewed here.
Roger, VK4YB, reported strong storms “in Queensland, NSW, and the Tasman sea.” and more of the same is in the forecast for the coming days. This morning he was using the JA antenna but has not received any reports for Japan during this session. In North America he has received reports from VE6JY, VE6XH, and WH2XGP.
Phil, VK3ELV, received a reports from JA1NQI and 7L1RLL4.
I thought this was a really good session. The fact that it was quiet goes a very long way with me in spite of no trans-Atlantic reports for my station during this session. I listened for WSPR-15 during the day from WD2XSH/15 and it seems that I decoded each transmit cycle that Don was on the air. I was unable to decode WH2XZO or WG2XKA but it was very early and any gains that might be achieved with WSPR-15 are still not enough over those daylight paths short of extraordinary band conditions. I transitioned to WSPR-2 at 2300z and it was a typical early evening. At 0115z I transitioned to CW and called CQ on 474.5 kHz for a bit, receiving RST 589 reports from Jay, KA9CFD, located in Illinois. The band was ripe for two-way QSO’s during the evening and I hope a few more guys will make sked and see who they can work. I transitioned back to WSPR just prior to 0200z for the evening and was pleased to share two-way reports overnight with WE2XPQ. My reception numbers were very good and near “normal”. Those reception report details can be viewed here. My transmission numbers were also very good with JT9 and CW-level reports through the evening and overnight. My transmission report details can be viewed here.
Activity was very good early in the session with 115 MF WSPR stations observed at 2330z on the WSPRnet activity page. There were 126 stations observed at 0200z.
Regional and continental WSPR breakdowns follow:
Eden, ZF1EJ, shared two-way reports with WH2XCR and experienced great coverage around North America. He decoded eleven WSPR stations and was decoded by 42 unique stations.
Fernando, XE2EJ, provided reports for eleven WSPR stations including WE2XPQ.
Laurence, KL7L / WE2XPQ, successfully setup a receive station on the beach in Maui during the evening! Using the SDR-IQ, an E-probe protruding from the window of the rent car, and an ultrabook, Laurence decoded a number of stations in North America, including WE2XPQ back in Alaska. Laurence reported that the medium wave stations in the area created a bit of intermod but were nothing like the QRM that he experienced at the condo.
Back in Alaska, WE2XPQ, experienced another nice session in spite of the lack of JA stations. By the time that this stations was active for the evening, unsettled conditions were setting in so its great to see the reports that he had, including two-way reports here at my station. DX report details for both of Laurence’s stations can be viewed here.
Merv, K9FD/KH6 / WH2XCR, had very good coverage of North America, with eastern reception reports for WD2XSH/17 and WG2XPJ, and two-way reports with WG2XKA, WH2XZO, and ZF1EJ. Merv also received reports from K4RCG and WA3TTS. Coverage in the West and Central portions of North America were also very good. In spite of very high noise levels in Australia, Merv shared two-way reports with VK4YB. He also provided reports for VK3ELV. Coverage in Japan was also solid, with reports from 7L1RLL4, JA1NQI, and JR1IZM. Laurence also shared two-way reports with WE2XPQ. Report details for JA, VK, KL7, and ZF1 can be viewed here.
