Hello all, I am monitoring 137.777 kHz now. ARGO screendumps can be found here: www.ndb.demon.nl/137kHz and updated every 10 minutes. 73, Roelof, pa0rdt
Hello Tobias, I did not get an answer, but the problem appeared to be more mundane. When I start ARGO as adminstrator, it works flawlessly. Apperently I did not install it as Administrator, so it had
Hello Alan, Thank you for the tip off. I re-installed ARGO in a different folder and now the capture function works as user as well. Best regards, Roelof, pa0rdt

Hello Laurence, It is the same story here. I have not heard a single Canadian NDB for 6 nights now. The last time this happened was in October 2012. The same applies to NAVTEX 490 and 518 kHz! 73, Ro
Hello Alan, Thank you for the information. I keep an eye on the Kyoto Dst and on he 17th it peaked +45. Such a peek often preceeds a major drop, however this one was very fast and deep. After the min
Hello Fausto, This RTTY sttaion is not very strong yet in the Netherlands. I have heard it before, however it is some time ago. The CW ID is given in FSK, which is logical for a RTTY staion! 73, Roel
