Hello Joe, my earlier posting came back as still undelivered after 8 hours I send this via the reflector. Sorry. I captured this picture on 21st of April 2340z of your 5WPM Signal. Your signal was au
Sorry Hartmut, and those who have been trying to email me. There seems to be a problem with the email here and so it looks as if amateur LF is more reliable than computer communications. I'm astounde
Dear LF Group, Very interested to see Hartmut's report of VO1NA's 5wpm signal. I have been doing some measurements on VO1NA's signal strength, and the band noise levels here over the past week or so,
Hello Jim, hello group, the SNR at his QTH must have been 10dB better than they were here, which shows the degree of variation that exists between different locations. Also a variation of the SNR exi
Over the last week or so, VO1NA has mostly been about -10dB to -15dB below the audible threshold. This gives good "O" copy at QRSS30, and would mostly be OK at QRSS3. But, at best, the signal has be
Peter and Jim and Group, Thanks for the reports and the very interesting comments. I have noticed on Brian's captures that there appears to be more noise centred around 137.777 kHz when the 5 WPM is

Last night I had some partial copies of Joe's 5WPM signal 0140-0200. The picture shows a callsign segment with QRM from the modulation of DCF39 during the "V" and the "N". The signal could be detecte
