I may have started the confusion about MMTTY.  I told Bob that due to  very little rtty on the air, he could use the mmtty program to simulate the signals coming off the air so he could test out his HAL demodulators.

I’m not sure I am following you, Bob. Why would you want MMTTY in the setup? Why not just use the ST-6000 directly to your radio? Are you saying you want both MMTTY and the model 15 working at the same time during a RTTY contact?
