Here the posting of a web watcher with my response:


Good logs and thanks for sharing, the graph represents the signal strength, noise and fading pattern which indicates a 22 db difference between minimum signal during deep fades to maximum signal strength, also indicating that fading is quite slow with this signal also indicating a fairly stable signal with not too great a noise encroaching upon the signal


  • Because I cant post inthe replies part of this blog , i post my opinions here and i thank the poster very much for his reply.
  • I agree with him for the whole message: short timed fadings occur with around 5-7 db cycles nearly every second which is as i call it short timed fading caused by convergence nd divergence of the signal.  There is the mid time fading at causes every 110 secs the   minimas up to -20db
  • The last fading curve seems damaged from possibly sudden  ionospheric turbulences.
