Actually you need to edit *BOTH* MMTTY.ini and USERPARA.ini.
Replace DefMarkFreq in *BOTH* files with your chosen MARK
(also "PITCH" in the K3 for AFSK_A and FSK_D).

There will be one instance of DefMarkFreq in MMTTY.ini and one
instance in each [Define  ] section (typically 10 sections -
Define0 - Define7 plus Define1025 and Define1026) in USERPARA.ini.
Note: some logging applications support 16 user configurations instead
of MMTTY's default of 8 - in those cases USERPARA.ini can have up to 18
Define sections!

I prefer 915 Hz tones, and I ran into the same problem. I learned that there are several things I needed to change. First is to change the HAM default. This will work fine, UNTIL you choose another decoding algorithm, like Flutter, and MMTTY will switch back to 2125 Hz.

To really solve this, you need to edit the USERPARA.INI file. With MMTTY NOT running, open file with Notepad, Search and Replace DefMarkFreq=2.125000e+03  with DefMarkFreq=1.275000e+03, and save the file.

When you restart MMTTY, make sure that 1275 Hz is set, and also that the HAM Default is is 1275 Hz.

I would prefer to use 1275Hz but when switching to transmit MMTTY keeps
jumping to 2125Hz. How to stop that?
