[WriteLog] more info on RTTY problem

[Jim Brown]

Rob,

While I don't know how this relates to your specific problem, I have 
learned that MMTTY uses two .ini files that establish the behavior of 
your instance of the program. These are plain text files, and it's well 
worth the effort to study them in a simple editor. One is mmtty.ini and 
the other is userpara.ini. The settings that I ran into are those that 
set the Mark and Shift frequencies, and they are present for all of the 
dozen or so decoding parameter settings. I like to work with low tones 
(915 Hz, 1085 Hz), while MMTTY defaults to high tones (2125, 2295 Hz), 
and these defaults are stored in the .ini files. mmtty.ini is your 
current (last) settings for the program, while userpara.ini contains all 
of the programmable decoder settings, like Standard RTTY, Fluttered, and 
so on. Each of those sets of settings includes the Mark and Shift 
frequencies.

The way this can bite you is that you may set MMTTY for 915 Hz, then 
toggle from one decoding algorithm to another with the TYPE button and 
MMTTY switches to 2125 Hz as set in those sets of decoder settings. 
These decoder settings also include AFC on/off (default is ON) and NET 
on/off (default is ON).

Once I discovered this, I went into those .ini files and edited them so 
they always come up the way I like to operate.

I went through and set up MMTTY in AFSK, using 915 mark frequency, 170 Hz, etc. I made sure ATC, AFC were unchecked. All looked good until the first time I logged a new QSO. The AFC button depressed (like magic) and the Mark frequency began floating. I never had this with version 11.

But, if there is data, and I log it by hitting “enter” it will “push” the AFC button every time. It is as if the log function and AFC invocation function are conjoined.
