Hello all, This looks like hearing ghost morse signals in the noise on a quiet band, albeit the process seems to be much more sophisticated! 73, Roelof, PA0RDT
Hello Joe, Your signal was best until about 04:30 UTC. It faded out completely and made a weak come back before local sunrise. I have attached a recording made with a normal CW bandwidth of 500 Hz. T
Hello all, It has been quite a while since a WSPR T/A decode has been found in the Netherlands: 2015-01-23 02:30 WG2XKA 0.475725 -26 0 FN33lq +30 1.000 PA0RDT JO11tm 5546 3446 Best regards, Roelof ==
Hello Joe, Already aural copy in a 16 Hz bandwidth in the Netherlands at 23:14 UTC. 73, Roelof, pa0rdt Middelburgg, JO11tm Perseus SDR + pa0rdt-Mini-Whip
Joe, Your signal was audible for the better part of the night; the dash at least. On a few occasions I had good aural copy of the call etc. Propagation was far from smashing though! 73, Roelof, pa0rd
Hello Joe, Propagation was much better than the night before. I have attached a soundclip of reception of VO1NA at 03:35 UTC. Similar reception was possible over the course of the night. The signal f

Joe, I had again aural copy of your signal, however much weaker than the night before. The Kyoto Dst dropped to minus 65 overnight and conditions followed suit! 73, Roelof, pa0rdt
Hello Joe, LF never ceases to amaze me! Against all odds, your signal was providing aural copy in CW mode and a filter bandwidth of 500 Hz around 04:00 UTC. Best regards, Roelof == From: Roelof Bakke
Hello Laurence, I found just a single decode from WG2XJM at 05:10 UTC. Propagation has been better! The change in time of sunrise is 2 minutes here, which is not too bad! 73, Roelof, pa0rdt
Hello Joe, Did you start transmission already on 137.777? I have a clear "V" here starting at about 21:10 UTC. Unfortunately for some reason the capture function of ARGO does not work. Does anyone kn
Hello Joe, My ARGO capture function does not work (yet), but this is what I received so far. Not too bad, I guess! Best regards, Roelof == From: Roelof Bakker, pa0rdt Location: Middelburg, Zealand SW
Hello all, It has been many years, since I have monitored 137 kHz. Recently I have build a new PC and upgraded my internet connection. Running a lot of programs simultaneous is very smooth now. I mi
John, Thank you for the info. At the moment, I am rerunning my PERSEUS recording to copy WH2XIL. Yes, the frequency readout is about 0.12 Hz high. 73, Roelof, pa0rdt
Hello all, Attached an ARGO capture of WH2XIL as received 13 hours earlier than given on the picture. Best regards, Roelof == From: Roelof Bakker, pa0rdt Location: Middelburg, Zealand SW Netherlands,
Hello all, I have started the ARGO ftp upload feature. A new screendump is uploaded every 10 minutes here: http://www.ndb.demon.nl/137kHz/ There is already a signal visible on 137.777 kHz. Joe, I for
Hello all, Excellent signals from VO1NA, WD2XES and WH2XIL on 137 kHz between 02:00 and 04:00 UTC. See attachment. Even stronger signals from VO1NA (audible) and WH2XIL around local sunrise, which is
