DXWin/MMTTY uses a separate copy of MMTTY. The first thing to do is
open the MMTTY set-up in WriteLog (Option | Setup) and make sure
MARK is the same as the MARK frequency in the rig (Demodulator tab),
AFC is *OFF* and Shift is *Fixed* or *FSK* (AFC/ATC/PLL tab) and
those values are saved as the "HAM Defaults". You can compare the
settings in WriteLog and DX4Win/MMTTY if needed.
If I set the mixer control to monitor the sound card input by
outputting it to the PC earphones, the K3 audio is there but very
weak.
Monitoring through Windows is not very reliable.
Tune a steady signal (e.g. the carrier from WWV) and set it to the
RTTY Mark Frequency. Set the RX Main or RX control on the microHAM
interface to 12:00. Open the Windows Sound Control Panel and double
click on "Line (microHAM CODEC)" (for MK II, DK II) or "mic (USB Audio
CODEC)" (for USB Interface III or DigiKeyer) and select the LEVELS tab.
Adjust the slider and the RX Gain pot until you see the first green
bar. With an S9 signal on my K3, that happens with RX Gain at 12:00,
the Windows input slider at 80% and the K3 Line Out at 10.
A more sensitive way to adjust audio input is to use audio spectrum
analyzer software (e.g. Spectran). Set the Windows input gain to 60%
and adjust the RX Gain pot on the microHAM interface so the background
noise level raises 30 to 40 dB above the no input nose floor of the
sound card. With my K3 that occurs with RX Gain at 9:00, Windows input
gain at 60% and the K3 Line Out at 10. By setting the no signal noise
30 to 40 dB about the sound card noise floor, signals remain well above
the noise floor even when the transceiver's AGC is activated and strong
signals do not clip/saturate either the transceiver or the sound card.

I'm having similar problems as Courtney described. Any help appreciated..
In my case, it's WL 12.12C and Win 10.
Rig is K3, and microHAM DK II. Rig control works fine. CW works fine.
If I set the mixer control to monitor the sound card input by outputting it
to the PC earphones, the K3 audio is there but very weak. Even if I
increase the K3 LINE OUT volume to max MMTTY starts complaining of
overload. It sounds weak but OK at the PC mixer, but won't print. Sound
card audio levels are already maxed out. MMTTY shows little or nothing. I
have not tried any other software since I do RTTY only once every blue
moon. I just wanted to get on and give out a few Qs to the deserving.

well, I did NOT have fun this past week end in the ARRL RU test. Ended
up with 25 contacts.... spent most of both days trying to get anything
to print out. So here is the set up: ft5000, microHam keyer 2,
writelog/xmmt/mmtty, WIN 10... this set up has worked great with my
2000D. Here is the weird part: using same rig with DX4WIN/mmtty, no
problem printing; mmtty stand alone, no problem printing, Gritty no
problem printing. I ran gritty window along side writelog and gritty
would print close to 100%; writelog much of nothing. I tried every
adjustment to software and rig that I could think of. All is set as per
aa5au/microHam set files. Nothing I tried improved the situation. Only
two variables that I could think that changed were all of my antennas
were covered in ice and I up-graded writelog to 12.12C version 3 days
before the test( bad idea, I know). I just could not figure what had
this applecart so upset. So I am in the dark here and would sure
appreciate any idea/advice on what/where to look. It seems to me that
the commen denominator is 12.12C. HELP!!!! thanks, 73's Cort K4WI
