BTW, Bob... ...did you ever try to leave a trace on the LF grabber of Edgar J. Twining in Tasmania? We were trying this spring/fall period but, so far, without success. I will make another attempt to
LF, Is there a trace of my signal on that grabber? I can see something, very weak, and only if you know the frequency and what letter was sent to which time. But it is close to my QRG, a shift of may
Edgar, Stefan, yes, I think it's there. On the Orford grabber around 15:40 UT, it looks like four dashes belonging to a "7" and the first dash from the following "F". Also later perhaps some more bri
Hi Stefan, and group, The equipment at Orford had been set-up for only a month to try to receive Stefan's signal during Equinox. I now have permission from the land owners to run it there for the nex
Hello Markus, LF! Yes, i saw these 3 dashes (which are "dits" on that QRG and time) in one line. And if they are from me, it must be the end of the 7. And i was transmitting the 7 just to that time.
Stefan, Edgar, the inset was taken from a local grabber screenshot http://dl.dropboxusercontent.com/u/26404526/df6nm_Eu_131101_1710.jpg, which was reduced in width to 50% to account for different scr
Hi Markus, Stefan, Is it possible to search for the dashes using cross-correlation? A wave file of the signals received at Orford is available. Format is 16 bit, 22050 Hz. Unfortunately I would have
Hi Edgar, yes crosscorrelation would be possible, but I doubt that there will be a large additional benefit. One method would be image-based spectrogram cross correlation. Some time ago I have tried
Hello Edgar, Don't you have a remote access to that PC in Orford? So you could install a Dropbox there and simply upload the file and then provide a link so we can download it from here. You are righ

Hi Stefan, You are correct on both suggestions. Drop box and Teamviewer are being used. The problem is with the small PC and limited internet connection. What time period are you interested in? I cou
