Hi Frank, I am not familiar with those cables, but the one with 2 3.5 MM
jacks are your audio in and out, wich would plug in to your soundcard,
line-in and audio out. The other cable with the DB9 connector is for
push to talk. The cable must have the interface already in it, as that
is what you need from the db9 to key your ptt. You need to find out wich
din connector has the audio signals on it, and wich one has the ptt
connection. Hope this helps!
