                Long delay echos 
              Mailing list: <GQRP.yahoogroups.com> 
                
              Just seen the link to 
                the long delay echos 
               from Peter 
                Brogl, DK6NP on the 
               Southgate 
                Amateur radio website:  
              http://www.southgatearc.org/news/december2010/long_delay_echoes.htm 
                 
              I've 
                not yet seen anything about the power 
               
                he used or details showing if 
               
                the echoes spaces were EXACTLY the 
               
                same on each transmission. A  
              detailed 
                comparison between the  
              transmitter 
                and echo keying envelops  
              may 
                confirm that they really came from  
              DK6NP's 
                transmitter and not some 
               
                elaborate hoax. If genuine, surely this is a  
              remarkable 
                and tangible 
               
                example of this very odd (and rare?)  
              phenomenon.

              At the peak 
                of recent sunspot cycles it was 
               
                not that unusual to hear  
              echoes 
                on 10m from signals that had gone 
               
                around the globe both ways 
               
                even several times. One could certainly  
              envisage 
                occasions when signals  
              get 
                trapped between some ionospheric  
              layers 
                and eventually "escape"  
              back 
                to earth - like a very extended chordal 
               
                hop.
