I am using the latest version of SmartSDR and MMTTY v1.66G. I am in DIGL mode and have selected DAX channel 1 in Slice RX A and selected the DAX button in the P/CW window. I am able to decode RTTY signals in MMTTY OK but cannot TX. I suppose I need to get the PTT signal from SmartSDR to MMTTY but cannot figure out how to do this. Have Googled to no avail. Help!
