Hello Joe, Good propagation last night and it was no problem to copy your CW signal by ear. See attachment. This is an interesting picture as it clearly shows the keying sidebands of your signal. The
Hello Joe, Unfortunately propagation went down / shifted to other directions and no aural copy could be achieved. And there was quite a bit of static at the start, which tapered off later on. However
Hello Joe, Propagation was excellent last night, albeit with deep fading. See attachment. The background noise was increased due to static rain, visible as green horizontal bands. Easy aural copy. 73
Hello Joe, Excellent propagation once more! Even better than yesterday night. 73, Roelof, pa0rdt The following section of this message contains a file attachment prepared for transmission using the I
Hello all, Last night I did receive on NAVTEX 518 kHz Boston, USA and Portsmouth, USA. So there was a path to that part of the US. So far I have not seen any T/A WSPR reception this season, but last
Hello Joe, Propagation has improved further. See attachment of my Linrad fast playback. Even the second harmonic of the keying sidebands are clearly visible. I will sent two more attachments in diffe
Hello Joe, This is your normal speed CW as received on my PERSEUS waterfall. Note that this is not in QRS mode, but 10 WPM Morse. Best regards, Roelof == From: Roelof Bakker, PAoRDT Location: Middelb
Hello Joe, This is the last attachment: an audio clip of your signal in a normal 500 Hz wide CW filter. Time of recording: 05:20 UTC Best regards, Roelof == From: Roelof Bakker, PAoRDT Location: Midd
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
Hello Clemens, Attached is the my Linrad overnight graph of VO1NA on 477.7 kHz. The path was still there, but is certainly effected. There was a lot of static snow, which explains the high background
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
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
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
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
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 Paul, This is my overnight plot around 137.455 kHz. Best regards, Roelof == From: Roelof Bakker, PAoRDT Location: Middelburg, Zealand SW Netherlands, 51 30 02 N, 03 36 02 E Locator: JO11tm Rece
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
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
Hello Joe, Propagation was smashing and there was no need for narrow filters or coherent detection. Excellent aural copy in a 500 Hz or 2400 Hz filter! The overnight plot shows also nice the fading p
