Hi! I am not able to achieve ptt with DX4WIN using MMTTY, PSK31 CW, etc. If I manually close ptt with the foot switch or mic I get keying. Any ideas? All programs work fine stand alone; meaning MMTTY, the various PSK programs, etc. All work fine when using Writelog. Rig control works o.k. on Com 1 I have PSK ptt on Com 4 and FSK keying on Com5 73, Dave K7JJ
