Radio: it's not just a hobby, it's a way of life

Current Operating Frequency and Mode

OFF AIR but QRV after dark tonigth

SCHEDULED ACTIVITY: CQ 474.5 kHz CW by 1015z through sunrise most days, WX permitting

Only one trans-Atlantic station, WH2XRR reports KH6, WG2XSV and VE7BDQ heard by many in the east

It was a pretty good night for most stations although most would probably agree that it was a very different night from the several previous.   Doug, K4LY / WH2XZO, made an early comment that from his location in South Carolina that propagation seemed to be east – west only shortly after dark.  I noticed the same here in Texas but near sunset in Arizona, Ward, K7PO / WH2XXP, was being heard by Rudy, N6LF / WD2XSH/20 in Oregon, and Larry, W7IUV / WH2XGP in Washington state.  A nice propagation discussion ensued with Jim, W5EST, and Laurence, KL7L / WE2XPQ, in the ON4KST chat/logger where we tossed around magnetic inclination as a possible cause, K- and A-indices, and other esoteric ideas.  I’m not sure if by the end of the discussion we had many any progress or confused ourselves even further.  It was a good discussion, however.

It really was a very different session, though.  A G3-level storm was forecast  by the Space Weather Prediction Center but a look at the geomagnetic field suggested that maybe this was the quiet before the storm.

Geomagnetic conditions were pretty quiet through the session and DST had recovered from the excursion it appeared to take on Sunday.  Perhaps this was the cause for the weird east-west conditions which stabilized as the evening progressed.

As I write this near midday on Monday, daytime conditions in all directions appear strong, in fact much stronger than conditions through the day on Sunday which included a few reports in the Midwest.

Band activity was very strong, with WSPR being the primary mode in use through the session.  The 24-hour break down by region is shown below:

NA 110215

North American 24-hour WSPR activity


EU 110215

European 24-hour WSPR activity


JA 110215

Japanese 24-hour WSPR activity


OC 110215

Australian 24-hour WSPR activity

TNUKPJM reported VK3ELV for the first reception of Australia in Japan for almost a week.

The only trans-Atlantic activity for the session was between DK7FC and WD2XSH/17.

Noteworthy in North America is the fact that both Neil, W0YSE/7 / WG2XSV, in Washington state and John, VE7BDQ, in British Columbia were reported in the East by numerous stations.  In fact, Mike, WA3TTS, posted the following on the LOWFER reflector:

Congrats to Mike, Neil and John!

In the Caribbean, Roger and Eden did not seem to have problems hearing signals to the North:

It was very curious that FR5ZX was seemingly QRV again but not hearing any stations in Europe as he had in previous sessions.  During our discussion last evening we figured that propagation was simply poor as it was very early and our own signal were struggling to move north.  As it turns out, Stefan, DK7FC, just sent the following information from the RSGB “blacksheep” reflector:

why no FR5ZX 110215

Stefan also added the following information about the antenna system used during the major decode event a couple of days ago:

In Alaska, Laurence, KL7L / WE2XPQ, appears to have had a good night, hearing as far south as WG2XXM in Oklahoma.

In the Pacific, Merv, K9FD/KH6 / WH2XCR, had another very strong night, being heard by Eric, NO3M / WG2XJM, in Western Pennsylvania at a distance of 7413 km.  Merv continues to run decreased power until he has time to finalize the impedance matching at the antenna.  Not bad for 2:1 SWR and 10 to 20-watts TPO!

Also very notable were the reports from Bill, N3CXV / WH2XRR, who heard Merv at -22 db S/N.  To date, this is the furthest east that Merv has been reported.

Merv also indicates high noise levels through the session, 20-over-9 at times, which makes his receive log for the session even more remarkable.

It was nice to see the signal from KH6 visible in the waterfall around 475.749 kHz for several cycles:

Neil, W0YSE/7 / WG2XSV, made contact with Japanese SWL station TNUKJPM in the WSPRnet forum and made some inquiries about his station.  With a little luck Neil will be able to acquire information shortly about the antenna and receiver in use at TNUKJPM’s  station.

In an effort to extend 630-meter DX activity to active hams abroad, Doug, K4LY / WH2XZO, has begun contacting low(er) band DX stations that are geographically favorable for activity and might have an interest in trying out 630-meters, perhaps in a receive capacity using WSPR in preparation for US hams populating the bands.
