Re: LF: CW-R and IF shift

Bob,

 thanks for your information about the Icom rigs. The message from 
Jean-Louis seems to
imply that Icom is not consistent in all of their rigs on that choice.

I find much useful, to not make confusion, to use a graphical approach 
(in my mind):
I just imagine the filter shape of the radio, with the suppressed 
carrier indicated by a red point,
and the signal carrier as a vertical line which I mentally mode toward 
the red point. This line
will or will not pass through the filter shape depending on the filter 
position relative to the red
point. So, listening to the note coming from the speaker, I can, based 
also on the value of the
initial position of that line, judge whether the filter is placed above 
or below the red point
indicating the theoretical carrier...
A bit complicated to explain in words, much more easier to picture in 
the mind.
