[Dx4win] MMTTY

[Björn Ekelund]

Hi List,

Thank you for all the responses.

I now know %X/%e are valid macro tokens used to switch on/off FSK
transmission in the DX4Win GUI for MMTTY.

However the "ding mystery" remains unsolved.

I have made the following observations:

The loudspeaker ding is associated with using the %X token (start FSK
transmission) in a function key macro (e.g. F1). The %e (stop
transmission) creates no ding.

The actual sound made is called "Windows Background" and is also used
e.g. when changing the Windows loudspeaker volume using the mouse in
the system tray.

I have confirmed the issue on three different installations; A HP
Pavilion Desktop running Swedish Windows 10, an ASUS UL-30VT Laptop
running Swedish Windows 7 and an HP Folio Laptop running English
Windows 7.

The ding sound comes through Windows' general audio channel, not the
communications audio channel (which is used for e.g. the FSK audio
from MMTTY). If you use an extra sound card (like I ended up doing)
the ding will come through your loudspeakers and just annoy you.
However, more severely, if you use the PC's built-in sound card for
the FSK signal the ding will overlay with the FSK and distort the
first few characters of ALL your transmissions.

I have tried different settings in "keying setup" Alt-S with no effect.

I have tried placing the MMTTY executable in the default place
(c:\program files\mmtty instead of c:\ham\mmtty where it is installed
by default) with no effect

I have tried changing the settings on most things I find in the
Preferences drop down with no effect.

I have also played around with the standalone version of MMTTY and it
shows no such behavior (it uses backslash "\" as a token to turn on
and off transmission in function key macros.)

Am I alone in seeing this?
