There are 3 bandwidths and baudrates that fldigi implements in MT-63:<br><br><div style="margin-left: 40px;">500 Hz - 5 baud,<br>1000 Hz - 10 baud, and<br>2000 Hz - 20 baud.<br><br></div>The lowest frequency transmitted is always 500 Hz. If you have a scheduled MT63 qso or are trying to copy what you think is MT63 you should tune the signal so that the lowest observable signal is at 500 Hz. Fldigi is capable of decoding signals that are mistuned by as much as +/- 100 Hz.<br> <br> Long interleave and 8-bit extended characters are usually agreed upon before a qso exchange begins. The default is to use the long interleave. 8-bit extended characters allow the transmission of Latin-1 accented characters.<br><br>MT63 is used extensively in the Military Affiliate Radio System (MARS).<br><h4 style="text-align: center;"><a href="file:///home/dave/dev/dev.FLDIGI/FldigiHelp.working/index.html">Contents</a></h4></div></div></body></html>
