Thank you – I’ll look this over to see if it addresses the echo appearing 
differently in both the wide and echo graph.

Hi Gary

Have a look at these, which will hopefully help.

I like to use ECHO to test the station on 6M EME. 
 
But the latest version has changed enough I was wondering if there was a short 
help file for it? 
 
Also: The Echo graph will at times show the echo centered – and other times 
show it offset. I have a jpg showing a recent echo run where the echo was very 
strong – and it was showing it as the right numeric doppler shift, 96 Hz, but 
it was showing it on the graph as -96Hz and there was no SNR value reported 
(-99.0 shown). You can see the echo on the wide graph – you can see the echo on 
the echo graph – but both have it lower than it should be… 
 
A few minutes earlier I had 2 echos at -14.6 and others in to the low 20’s – 
these were all showing on the spreadsheet – and “properly” on both the wide and 
echo graphs.
