Olivia is a family of MFSK modes with a high redundancy Forward Error
|
|
Correction system similar to MT63. The family is very large, with 40 or
|
|
more different options, which can make it very difficult to work out which is
|
|
which. The mode works well on poor HF paths and has good sensitivity.
|
|
There are three popular modes, which have 8-FSK, 16-FSK and
|
|
32-FSK, thus having three, four or five bits per symbol. These
|
|
three modes can be selected without additional configuration. The
|
|
tone frequency spacing and integration period should always be left at
|
|
8 and 4 respectively unless you are experimenting with another station
|
|
running an Olivia modem that can be changed. These must always be
|
|
the same at both ends of the Olivia QSO. The modes have two
|
|
serious shortcomings - excessive bandwidth combined with slow typing
|
|
rate, and excessive latency which is the apparent typing delay caused
|
|
by the integration period.
|
|
<br>
|
|
|
|
Each Olivia transmission can start and end with two distinctive tones. These tones
|
|
are exactly at the lowest and uppermost tones for the selection of tones and bandwidth.
|
|
They can assist the receiving station in tuning the Olivia signal on the waterfall.
|
|
|
|
The start/stop tones can be disabled.
