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 sensitivit<span style="font-family: Verdana,Arial,Helvetica;"></span>y. 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 configurtion. 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><span style="font-weight: bold;"><br> </span>See <a href="Olivia.html">Operating Olivia</a> for additional information.<span style="font-weight: bold;"><br> </span> <h4 style="text-align: center;"><a href="file:///home/dave/dev/dev.FLDIGI/FldigiHelp.working/index.html">Contents</a></h4> </div> </div> </body></html>
