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

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.
