Hi All:

The WG2XWS call is in the FCC data base as issued to Northrop Grumman and based in Georgetown NJ. It appears to be a false decode even though more than one station reported it in the WSPR data base. As for the reported DH89 grid square, there is a very small chance one of those Easter Island Moai's was bootlegging ~:)

It was nice to see DK7FC decode the other evening.

Comparison to WG2XJM's decodes and SNRs is about typical for Eric's large RX arrays (Circle 8 or phased beverages) vs my
small garden EWE antenna. Eric's QTH is about 75~80 miles north of me.

Hi Rik,

thanks for obeservations and for evaluating the somewhat mysterious propagation
on MW into JN68.
There were other nights when even DH5RAE and DL0ABR didn't spot TA stations
and I was the only one in Europe.

But then there are nights when only Roelof,PA0RDT or Joe,DF2JP spot TA
stations.

Hi Stefan, all,



to get the facts right: there were many other EU's "listening"
at that time (> 30), but any one (you) at less than 500 km
from the JN68 group.

So it's not sure how focussed the propagation was. But is
nevertheless remarkable that serval other Eu's that are known
to have "good ears" didn't copy any TA last night.



BTW, in my earlier list I did miss the 05:02 UTC copy at
DL4RAJ, the complete sequence is:

It seems that the propagation peaked at +/- 05:00 UTC.

The fact that DL4RAJ copied most of it is probably due to his
"good ears" (last night DL4RAJ had 6 copies of EA5DOM, while
just 1 for DJ0ABR and nil for DH5RAE).



Maybe G3NYK and/or PA0RDT can link strange propagation this to
some propagation mechanism / solar event?

Wow, very impressive.
As we saw in the past, JN68 is a special field...

The dst plot showed a dramatical dip. On LF we think that
propagation must be down for days but on MF i thought there
can be miracles. Thus i started the TX over the night. And see
here, the miracle happened!

I just noticed very strange TA propagation on MF last night:



During a very short period (04:40 - 05:02) 3 US
stations were copied in southern Germany, but nowhere else in Europe:

The signals were partially very strong (up to -16dB)
and the 3 EU stations are located close together.

Also the distances are remarkable, up to 9367 km.

Based on WSPRNET data at least a dozen other stations
were receiving WSPR in Western Europe at that time, but not a
single copy from them!



During the same time period one German station was
copied in the US:
