Hi Everyone, Thanks to all the good feedback on this list, my problem is solved. As many people pointed out, the Mark frequency in MMTTY has to match the pitch setting in the K3. I checked the K3 (thanks to those who showed me how) and it was 2125 Hz as expected. I checked MMTTY and it was 473 Hz (where the heck did that come from???).
I reset the value in MMTTY to 2125 and was able to print RTTY in data mode with no problem. A few minutes later, had my first RTTY QSO with the K3. Worked perfectly. So, there was nothing wrong with the K3 and the only issue was the configuration of MMTTY. I am very greatful to all of you who responded and gave me the information to solve my problem.
