Title: VMW 2056 USB 1215 UTC 24 Jan 2017
Post by: ChrisSmolinski on January 24, 2017, 1221 UTC
I was not expecting to hear this. I was checking the A beacon on 2097 CW when I noticed some USB audio on the waterfall. Turned out it was VMW, Wiluna W. Australia with weather reports. Quite weak, but I could hear the Australian accented OM.

I was wondering what was the actual time you logged VMW?  Curious as to whether you had a long or short path reception?  Would be a great distance if it was via the long path. 8)

1215 UTC, so short path. I'll still take it  ;D

No reception this morning, nor either of the 120m stations as yesterday. So I guess it really was an exceptional opening, vs normal grayline.

How can one tell whether reception is long path or short path from the time a signal is copied?

That's a nice catch Chris. I logged VMW late in November 2015, long path I believe.

It faded in and lasted only a few minutes and then it was gone. I check for VMW
often on several freqs. I've never heard it again.

Where the sun is in relation to the two stations, as well as the time of reception and frequency.

On the low HF and MW frequencies, the reception will be over the dark path which, in eastern US mornings would be toward the west (the short path).
On higher frequencies like on 20 meters around local sunset, you can often hear Australian hams on both paths from the Eastern US.
