Lance, Thanks – but the issue is that the operation and displayed results – 
changed! It first was showing, on the Echo graph centered (0). And at the same 
time it showed on the wide graph as the echo was where it should be – i.e. 
1596Hz for a 96Hz echo doppler shift. And it decoded a signal with a level 
provided (-14.6, twice, w/ a Q of 10!). 

But then later – w/o changing anything other than time (i.e. later)… the echo 
showed on the Echo graph at -93 Hz (now the expected echo was 93 Hz)… the wide 
graph showed it just above 1500Hz and although there was clearly an echo – the 
tabulated results remained at a level of -99.9! 

This is all clear in the screen shot if anyone wants to see it. 

After reading the doc I did see that it was set to “on own echo”. I changed 
that to “none” and now it seems to work as expected – the echo is now at 1576Hz 
on the wide graph and is at +76Hz on the Echo graph – and it gave a proper 
numeric value (this time -20.3). 

So again – its that it changed and when it changed it was no longer functional 
as, even though the echo was clearly there, the value for SNR was ‘stuck’ at 
-99.9.

Hi Gary,

I have not followed the ECHO mode documentation, but it may be that on the Wide 
Graph, you see the trace coming back as doppler shifed, but (at least in 
previous 
versions) the ECHO mode moves the frequency around, along with its receiver, 
and just 
displays the sum total of the average echoes received. The program knows where 
it is 
transmitting, so knows where to listen for the signal. I don't think you need 
to pay 
any attention to what is shown on the Wide Graph...GL and VY 73, Lance
