Even simpler with 2Tone go to Setup, Settings and click on 75 baud within
the Speed box.

I do not recommend using FSK TX for transmission unless you are using at
least a 4 core multi-GHZ processor as timing jitter can be excessive. Better
to use one of the other transmission options.

The BARTG 75 baud Sprint contest is this coming Sunday.

Date, time and rules at: http://bartg.rsgbcc.org/cgi-bin/hfreadcal.pl

Remember, this is the SEPTEMBER contest, not April. 

There are the four steps to change MMTTY to 75 baud:

I use FSK only, but I assume this applies to AFSK as well. If not, please
let me know.

1. Start MMTTY and go to Options>Setup MMTTY and select the Demodulator tab.
2. At the bottom, UN-check the box that says "Fixes 45.45 baud".
3 Go to the Decode tab and change the baud rate to 75.
4. Click OK.  Do not skip this step or changes will not be saved.

This is a short contest - just four hours but lots of fun. 75 baud RTTY
plays differently from 45 baud. Please post your observations on the
Reflector after the contest. 

See you there!
