That graphic looks to me like 500 Hz wide 8 tones.
The bandwidth is the easy part to see from the waterfall - the harder part
is the number of tones. If you look closely at the display, you can see
eight stripes roughly defined in the display.
Could the sideband have been reversed? Last I
Andy,
Looks like a 500Hz width signal, looks like your set for a 1000Hz width,
OR it could be a CHIP64 signal, width looks about right. Looks more
like chip64 than a Olivia signal to me, wish I could here it!
20 meters and higher most use a 1000Hz wide Olivia, some call it
standard mode

Have on the air tests shown that 8 tones work better than 16 tones during
heavy QRM / QRN and poor condx? It would seem that
Mark,
Thanks for your info. on the tones/bandwidth, most of the user are
using the lower bandwidth on 30 and lower since we have limited space
and its share more with SSB, RTTY and the other digital modes.. The 16
tones 500Hz width gives us about a 20 WPM while the 8 - 500 provides us

Yes that is certainly a factor, but on 40 most of the time I hear Olivia
and other modes right on top of
Thanks Mark,
Makes it easier to understand.
