Note that MMTTY will only do 75 baud FSK if you are using a
real serial port, EXTFSK2 (EXTFSK64) or an interface that
provides a UART with 75 baud support.

The original EXTFSK (COMFSK 1.05) will not do 75 baud.

The BARTG 75 baud Sprint contest is this coming Sunday.

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!
