In MMTTY, check on the drop down menu under OPTIONS, then at the bottom
of the list, select SETUP menu, then TX pane. Be sure the Digital
Output is about mid scale. Also, make sure the computer SPKR level is
about 30 to 50% .
On the K3: From the MENU the MIC SEL should show LINE IN. The DATA MD
should be set for AFSK A and 45 BPS. The PITCH value should be 2125 -
170. The setting for LINE gain {use the MIC control} should be about 30.
This works for my configuration when running MMTTY.

Audio Mark and Shift in MMTTY are identical to the Pitch control settings
in my K3.
MAIN:AFSK TX is set to Filter On. This makes no difference for my transmit
power, however.

Line In is selected, I should have included that in my original posting.

Hi, I've recently upgraded my K3 with numerous upgrades including a KIO3B
board. I've successfully configured most of what I need but RTTY has been a
problem.
What I see is that I am able to transmit power in RTTY mode if my K3 is
set into *DATA A* mode. If I set my K3 to *AFSK A* mode, the radio has
the appearance of transmitting in RTTY mode but there is no power. IE, TX
illuminates, the ACL meter moves. But Monitor is silent and there is no RF
power. MIC gain is set the same for both modes. VOX is set for both (not
PTT).
The problem first showed up in DXLAB WinWarbler. However, I've confirmed
the exact same problem occurs when I am running a stand-alone MMTTY
executable.
I realize that I could use an external FSK interface. But I"m looking for
a simple setup, and the documentation I've seen indicates that I should be
able to obtain output power using *AFSK A* mode.
It appears to me that there is an audio routing issue in my K3. However,
that seems unlikely, as others would have reported the issue and it would
have been corrected. What I'm hoping is that there is a simple setup issue
that someone can direct me towards.
Any ideas would be extremely appreciated.
