Is your mark tone the same in both MMTTY and the K3? The AFSK TX audio filter will dump any audio outside a very narrow range.

I have always used AFSK data mode with MMTTY for all my RTTY contests and operating. I have since upgraded to a new PC (Windows 10) and for some reason after re-installing all my programs, I can only get tones out on the K3 when I change to DATA A mode. I know it is not my sound card and have looked over all my settings in MMTTY. Not sure where to look next. Thanks,
