[Elecraft] Digi modes using computer?

[Bill Maddock]

K3 users:

  I am trying to get my K3 to work with computer on PSK - RTTY
and SSTV. I recieve fine but I have no PTT to transmit. I have it set up
on COM 1 as the logging software recognizes it (DX4WIN) but no transmit
Any ideas what I might be doing wrong?

Thanks and 73 Bill N4ZI  K3 #1059
