[TenTec] ARGONAUT V QUESTION

[burro5944 at bellsouth.net]

JUST PURCHASED THE CABLE TO OPERATE PSK31.
Sorry for the caps lock.
anyway how is the radio keyed for transmit. the cable has 4 female RCA 
phono plugs on is to be line in one is line out and one I believe is to 
key the PTT but there is no input on the radio.
Also I had to buy 2 male to female 1/8"  Male is RCA phono female 
accepts a stereo cable which goes to the sound card of the computer will 
the stereo plug to the computer work as the cable from the radio line in 
and out is mono.
Now have I totally confused everyone as well as me. HiHi
FYI I have never worked this mode before so I am on my own with the help 
of all the TenTec Gurus (sp.) I believe I spelled it right.
