Hi group. As suggested by Mike W0YR (thanks!) i wish inform you that i'm trying to use Logger 32 bit for RTTY activity. Can i use FSK or AFSK via rear connectors on my rig (Yaesu FT1000MP-MK5) and sound card on PC? It is necessary a interface? What? My more relevant problem is the PTT command... Please help me!!! Thanks in advance. 73 de Enzo IT9GKQ
