[Elecraft] RTTY Keying problem

[N4QS]

To all,

I had a computer crash yesterday and have spent the weekend reinstalling ham radio software and interfaces on a replacement pc.  I almost have everything working except that I still can't get DX4WIN to key the K3 in RTTY AFSK A mode.

I use MMTTY and DX4WIN.  Maybe someone can help refresh my memory.  I have the K3 Data Mode set at AFSK A.  I have always used AFSK A with the K3.  The K3 PTT-Key setup in Configurator is set as DTR - RTS.  If I run MMTTY outside of DX4WIN, under MMTTY Setup, TX tab, I have PTT & FSK port set at None.  If I go into DX4WIN and bring up the RTTY window and then do an Alt-S, I show MMTTY Keying setup as Vox and key line set as DTR.  I am using Com1 for radio control between the pc and K3.

I can receive fine, but just cannot key the K3.  I wonder how you are setup?  It was working perfectly until the crash!

Thanks,

Dave, N4QS
