[TenTec] PSK Interface

[wo8l@att.net]

Hi,

How do I interface an OMNI V to my computer for PSK.  
Receive is easy.

However, I cannot transmit by connecting to the "audio 
in" plug on the back of the rig.

Do I need to go directly through the microphone plug on 
the front of the rig?  Do I need an external interface?

Thanks in advance,

Rick
