Hi Markus, That's remarkable! I'm inspired. Tnx 73 Joe VO1NA Hi Joe, on the spectrogram https://dl.dropboxusercontent.com/u/26404526/opds8.png , your carrier trace was quite narrow so conditions were
Hello Markus, I have followed your and Paul's experiments with great interest and have great respect for the ingenuity involved. Looking at my plain CW reception of VO1NA, you might understand that s
Hi Roelof, Marcus, with a bit of luck this is just an appetizer of what we can expect the coming years when we are going toward the solar minimum. In 2009-2010 winter I could hear Joe (VX9MCR at that
Hello all, Attached last night's reception of VO1NA. Between 01:15 and 01:25 UTC, marginal aural copy was possible in CW mode and good aural copy in Linrad's coherent mode. As can be seen, the band n
Hi Roelof, thank you for those comments, that was my feeling but there is so much recorded informationI thought it was worth a look and sticking my neck out to see if anyone would say I was all wrong
What is needed, is a software package that runs in parallel, monitoring and recoding the noise level. It would have to work in a manner that was unaffected by the presence of signals, and also on a
Just a thought: what if I could set up a local WSPR station (let's say at 10 km from my QTH) that transmit 100% of the time with very low power (so it is centrainly not overloading my RX). I would ex
Hello all, Signal to noise ratio is arbitrary as both are effected by unknown factors. The figure of merit for propagation is signal strength and that can be easily measured with Linrad, Spectrumlanb
Hello Joe and all, The latest screen-shot of VO1NA's overnight signal has been attached. There was mild static originating from the area around Corsica and mid Italy. Towards dawn propagation from th
Hi Roleof, Group, Good to learn that it is still being detected across the pond. The TX is back on again CW, 10 WPM. 73 & TNX Joe VO1NA Hello Joe and all, The latest screen-shot of VO1NA's overnight
Hello Joe and all, Easy aural copy around 23:00 UTC without the need for coherent detection. A complete different propagation pattern compared to yesterday. A weak post-sunrise (at my location) enhan
Thanks again, Roelof for your dedicated monitoring. Perhaps as conditions improve the CW will be audible again. 73 Joe Hello Joe and all, The latest screen-shot of VO1NA's overnight signal has been a
Hello Joe, Last night you signal was weaker, but still strong enough for aural copy at 03:00 UTC, thanks to the amazing coherent detection of Linrad. 73, Roelof, pa0rdt The following section of this
Good to be heard again, Roelof. TX is on again. 73 Joe Hello Joe, Last night you signal was weaker, but still strong enough for aural copy at 03:00 UTC, thanks to the amazing coherent detection of Li
Hello Joe, Last night your signal peaked at exact the same time and could be copied by ear. 73, Roelof, pa0rdt The following section of this message contains a file attachment prepared for transmissi
Hello Joe, Excellent aural copy at the same time again. The signal was not stronger, but the band noise was much less! That made a large difference. See attachment. 73, Roelof Bakker, pa0rdt The foll
Hi Roelof, Thanks for the great capture. The beacon is on again tonight. 73 Joe Hello Joe, Excellent aural copy at the same time again. The signal was not stronger, but the band noise was much less!
Hello Joe, Last night's plot looks very similar to the previous one. However, your signal peaked one hour earlier. Excellent aural copy once more; also on my PERSEUS recording / playback. 73, Roelof
