Re: LF: DK7FC in VK (March 18/19)

Hi Dimitris, Stefan,

 

the attached clip is a part of what was visible on the VK1SV grabber

http://people.physics.anu.edu.au/~dxt103/grabber/ 

at 20 UT, ie. around sunrise on the Australian east coast. Timing and frequency of the "FC D" coincide with my local observation of what has been sent by DK7FC.

 

Pretty impressive, isn't it!

Thanks Markus,

A picture how the path looked today at 18:36 UTC:  http://dl.dropbox.com/u/19882028/LF/VKstillindarkness.png Can't show it completely in a 3 D world map ;-)

Comparing VK1SV screenshots to my local Eu window, I can confirm that Dimitrios saw Stefan's signal again tonight around 18:36, catching parts of "7" and "F". Well done again!

 

On his grabber, the time is shown as 18:46 (ie. currently 10 min offset). The frequency scale seems to be 0.10 Hz low. G3KEV was actually transmitting on 136172.835 Hz, but unfortunately no matching traces could be identified.

 

The VK1SV grabber also features a DCF39 window, which should be an excellent propagation indicator for Europe. Strangely there seems to be no visible trace at all on 138830.6 Hz. Comparing this to last month's observations, Stefan only came out of the noise in India when DCF39 (and also HGA22 on 135430.0) was at least 25 dB SNR in 1 Hz (or 35 dB in its "natural linewidth" 0.1 Hz).

Thanks to all for the nice words!


NOW: It comes through again:  http://people.physics.anu.edu.au/~dxt103/grabber/
Even earlier than yesterday. Looks promising for the next hour :-)))))))))))))))))))))))))))
