Digital Sound - Olivia



Olivia is a fairly new digital mode and it seems to be extremely resistant to fading and QRM. I can get full copy on stations that are barely audible (even ones that fade down to almost zero seem to still print well). As with other modes, Olivia has different variants each having a different bandwidth (from 500Hz to 2kHz) and different number of tones. Olivia can be very slow (in the order of 2-3 characters per second) but a slow contact is better than none at all! In the below pictures, the 8/250 indicates 8 tones over a 250Hz bandwidth and 32/1000 is 32 tones over a 1kHz bandwidth. To avoid interference to other stations is it usual to start an Olivia transmission on a full kHz (i.e. 14.108.0 rather than 14.108.3 for instance).
