Dear LF group, for some time there has been a blue line on 136955.90 Hz, in the middle of my SpecLab screen (http://members.aol.com/df6nm/Grabber.htm, now updating every 10 min). It is probably the CFH carrier mentioned by G3NYK and monitored by CT1DRP. This is what I had always wished to have for W-E propagation monitoring - a narrow line that can be received with millihertz resolution, and (hopefully) clean and weak enough not to clutter up the band in America. The line was visible in Nuernberg during most of the daylight hours, and peaked to ~3 µV/m around 21:15 this evening - looks like conditions may to be improving. If somebody could make a measurement of CFH within ground wave range, we could estimate their radiated power and make guesses on ionospheric path attenuation. Best wishes Markus, DF6NM |
