Hello Joe, Attached another Linrad overnight plot of your 478.477 kHz OP8 signal. This was again received on the RTL-SDR dongle. The beauty of SDR technology is that in Simon Brown's SDRConsole V3 up
Hello Graham, You might have seen my overnight plot of VO1NA. The signal starts out very weak and at first is obliterated by static interference from south Italy. This will be far less the case in No
Hello Graham, For direct sampling of the RTL-SDR V3, I am using SDR#. However, I have now changed to an Afedri SDR. I mentioned SDRConsole V3 as this is what I use with an Afedri SDR. My current Oper
Hello Graham, Propagation was considerable worse. See attached Linrad overnight plot. Besides mediocre propagation, after 02:00 UTC the fun was also spoiled by static rain. 73, Roelof, pa0rdt The fol
Hello all, Last night reception on 630m was severely effected by static rain. See attachment. I have often noted that the effect of static rain is worse for > 450 kHz and that it is almost completely
Hello Stefan, Thank you for your input. I will look into it. Though not visible in the spectrum plot, the inteference also dropps off at higher frequencies. It is gone above 1 MHz. 73, Roelof, pa0rdt
Joe, The sun is playing havoc once more and your signal was quite weak. See attachment. No chance for aural copy, but Opera made it. 73, Roelof, pa0rdt The following section of this message contains
Hello Joe, Propagtion is a weird thing. Yesterday was excellent, but last night was just so, so! The sun is playing havoc onc emore, I'm afraid. You signal is clearly visible, but no aural copy. Best
Hello Joe, I found nice reception of your QRSS signal on 137.777 kHz. See attachment. The signal peaked about half an hour before local sunrise, which happens at 03:35 UTC today. Best regards, Roelof
Hello Joe, On closer inspection, I found that your signal achieved aural copy in a 15 Hz bandwidth as well. A 20 second audio clip is attched. The signal goes off after 9 second. The beatnote is 400
Hello Joe, Decent copy of your 137.777 QRSS100 signal last night. See the attachment. I could hear it in my headphones as well! On the 13th of July, propagation from your part of the world was stunni
Hello Markus, This is what I received last night: DL6II G3XDV DF6NM R7NT (weak) G3JNT See attachment. Best regards, Roelof == From: Roelof Bakker, PAoRDT Location: Middelburg, Zealand SW Netherlands,
Joe, Rather poor reception as propagation was a bit unsettled by a geomagnetic storm. 73, Roelof, pa0rdt The following section of this message contains a file attachment prepared for transmission usi
Hello Joe, The night from 20 to 21 July, your signal was very weak and hardly if at all discernable on my Linrad waterfall display. Last night was just a little better. See attachment. As far as prop
Hello Joe, Here is another screenshot of last night from 03:15 to 03:50 UTC. This signal level gives marginal aural copy and is a nice example of the excellent sensitivity of Linrad's waterfall displ
Hello Joe, I will look for your signal. With my full overnight recording set up this is very easy to do. You might even be able to work David if propagation helps a little. At times summer propagatio
Hello all, Now something different: It looks like a severe radio black out of HF is ongoing. I have never seen this before. See attachment. This is also an opportunity to look at PLC interference at
Hello Joe, Due to numerous solar flares, lately propagation from your part of the world to the Netherlands has been very poor indeed. Despite the high sensitivity of Linrad's waterfall display, nothi
Hello Joe, Propagation changed for the worst. Your signal is clearly visible, but no aural copy, I'm afraid! 73, Roelof, pa0rdt The following section of this message contains a file attachment prepar
