MT63 is an orthogonal frequency division multiplexed mode consisting of 64
|
|
parallel carriers each carrying a part of the transmitted signal.
|
|
There are 3 bandwidths and baudrates that fldigi implements in MT-63:
|
|
<ul>
|
|
<li> 500 Hz - 5 baud </li>
|
|
<li> 1000 Hz - 10 baud </li>
|
|
<li> 2000 Hz - 20 baud </li>
|
|
</ul>
|
|
|
|
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.
|
|

|
|
Selection of interleave (short/long) is made from the modem menu;
|
|
MT63-500S, MT63-500L, MT63-1000S, MT63-1000L, MT63-2000S, MT63-2000L.
|
|

|
|
|
|
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.
|
|

|
|
|
|
To assist the Rx operator you can transmit a short tone at the lowest
|
|
(and highest) tone frequencies. You can set the tone duration.
|
|
<br>
|
|
|
|
You may also elect to use manual tuning (position on the waterfall) of
|
|
the Tx / Rx signal. Be careful when doing this so that the signal
|
|
does not extend beyond the limits of your transceiver SSB filters.

MT63 is used extensively in the Military Affiliate Radio System (MARS).
