I have an interesting GIF image from Funk Amateur (Feb/1999) that shows the
relative width of CW signals at 20wpm and a clean PSK31 signal. If anybody
is interested in looking at this, I have placed it on my web page (this list
does not permit GIF images for posting).


If the above direct link gives problems, go through my primary page:


Look on the left side of the web page display for the "Screen images", "CW
Band width" link.

Hopefully, this is a reasonable representation. Unfortunately, the article
does not give the rise time of the 20 wpm signal.
