Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

Trans-Atlantic reports continue to roll as geomagnetic conditions calm again but southeastern US storms continue to create lot of problems for the eastern half of the US; Formal announcement of the upcoming Midwinter 630-meter Activity Night

– Posted in: 630 Meter Daily Reports, 630 Meters

The summary for January 23, 2016 can be viewed here.

Propagation was relatively good but it was tough to realize in the central and eastern portions of North America and the Caribbean as the storm system that has been creating so many problem across the South  finally reached the Atlantic coast and pushed out to sea.  QRN here was down by as much as 40 dB overnight and hearing was moderately improved.  Stations in the East like WH2XZO and WI2XBV can’s share that sentiment, however.  There are a lot of stations coast-to-coast that are off the air, riding out bad weather conditions in their local areas.  Tonight is another night and I suspect that as far as noise is concerned it may be a session that is more consistent with what we expect for January.  I hope so.  Prime band conditions are being wasted.

11-hour North American lightning summary


Geomagnetic conditions have returned to quiet levels with a Bz that is pointing to the North and solar wind velocities in the moderate category, averaging 425 km/s.  DST values have rebound and remained stable near unity.  Perhaps we will see a few more days of recovery before the next event.




Trans-Atlantic reports were pretty good again but there were a few more holes in reports and it involved numerous stations that were off the air.  The following list details stations who were reports on trans-Atlantic openings and the stations that heard them:






Its great to see high latitude openings returning for WH2XXP and WG2XXM.  That’s a long haul.  Report details for these stations can be viewed here.

Ken, K5DNL / WG2XXM, reported that he heard seven WSPR stations through QRN and  received reports from 57 unique stations including LA2XPA, F1AFJ, and G3XKR.

Rick, W7RNB / WI2XJQ, reported a lot of strong signals in his area but nothing further East of me due to the extremely high noise levels.  Rick decoded nine WSPR stations and was decoded by 22 unique stations.  Rick’s unique report detail can be viewed here.

Ernie, KC4SIT / WI2XQU, submitted the following comments for the session:

“Heavy rains throughout the night (some of the heaviest I remember in years). Noise levels ran between S7-S9 throughout the night here in Flat Rock NC. Utilized the Icom 7200 and 160m inverted L with traps of 80/40 meters. Preamp was off. I had a count of 4 unique spots…”

KC4SIT session WSPR activity



Roger, G3XBM, reported that he was beaconing with JT9 overnight at 5 mW ERP and received a report from G6AVK.  Roger indicates that in recent WSPR sessions he received reports from eleven unique stations in five DXCC entities at the same power level and even decoded part of a JT9 QSO in the previous session.  JT9 is a great mode for QSO’s but can be several dB down from the WSPR detection limit and extreme low power can definitely complicate things.  Nick, M0HGU also reported that he was on the air with 600 mW into a 10-meter tall vertical with limited ground system but indicated that he received no reports.  Roger reports that he is on the air again tonight so hopefully he will find some additional success with reports and maybe even a two-way QSO.

Trans-Pacific report details, excluding KL7 and KH6, can be viewed here.

Roger, VK4YB, reported that “Summer static continues down under, but Ward, WH2XXP, managed to get through. Single spots from Larry, W7IUV, Steve, VE7SL and Laurence WE2EPQ, prove the path is still open.”

Ward, K7PO / WH2XXP, received reports from sixty stations, including VK4YB and the previously reported LA2XPA.

A very windy day meant a late started for me but I was on the air before full darkness.  I debated about running CW around 0130z but the noise level was likely too high for any real benefit so I opted to remain on WSPR.  Openings were there but S/N was clearly impacted by noise which was down to S-7.  I was happy to receive a single detection limit report from G3XKR.  Reception here was moderately better but I expected a significant improvement tonight.  WSPR transmission report details can be viewed here and WSPR reception report details can be viewed here.

WG2XIQ 24-hour WSPR activity


Fritz Raab, W1FR, submitted the following announcement for the upcoming Midwinter 630-meter Activity Night, scheduled for Saturday night (North America), February 4, 2017.   This announcement can be viewed here.

Activity was high but off of the record high observed in the previous session, with 103 MF WSPR stations observed at 0109z on the WSPRnet activity page.  AH6EZ/W7 was reported as listening during this session but I think he has been active in previous seasons.  Welcome back!

Regional and continental WSPR breakdowns follow:

North American 24-hour WSPR activity


European 24-hour WSPR activity


Central / Asiatic Russian 24-hour WSPR activity


Japanese 24-hour WSPR activity


Australian 24-hour WSPR activity


Eden, ZF1EJ, reported S9+ QRN during this session and one of the most impacted session at his station on record.  He managed some reports and it seems that a two-way QSO attempt may occur in the near future with VE7SL.  That path has been open recently, although briefly.  Eden decoded signals from three stations and was decoded by seven unique stations.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, had a big night with reports along the West coast of North America, two-way reports with  WH2XCR, reports for VK4YB and reception reports from 7L1RLL4, JA3TVF, and JH3XCU.  Its nice to see these types of openings.  He also continued to receive reports from WH2XCR after sunrise in KH6.  Laurence reports yesterday morning that there might be a slight auroral glow through the clouds.  Report details for JA, VK and KH6 can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, managed to share two-way reports with VK4YB and WE2XPQ.  In the previous session Merv was involuntarily absent late in the session due to high winds causing a power outage.  Merv indicated that things are better today and there was no damage to his 630-meter antenna.   It was still too noisy here to hear Merv but I am hopeful about tonight.  Coverage along the western US was solid and as reported earlier, decodes of WE2XPQ continues until after sunrise in KH6.  Report details for VK and KL7 can be viewed hereUPDATE:  It seems that a few reports were missed for John, VK2XGJ.  These reports are not in the WSPRnet database but John was kind enough to send me a screen capture from his WSPR console and those reports are appended below.
