[TenTec] PSK31 and OMNI VI Plus

[Charles Greene]

Rick,

I use the RCA plugs in the back for mike in and audio out.  From the sound 
card Line out, it goes to a 10K pot.  From the swinger on the 10K pot, to a 
1:1 radio shack isolation transformer and to the RCA plug for audio 
in.  From the RCA plug audio out, it goes to the Line in, or microphone if 
your sound card has no line in.  I have also used an isolation transformer 
in this line and it helps reduce the hum on the screen display a 
little.  To key the rig, the key line and the rear PTT line are in 
parallel, so a single 2N222 transistor or 4N25 opti-isolator will key CW or 
PTT.  There are several keying circuits on the Internet, or you can buy 
one.  To adjust the audio, use the windows sound a=]card controls, and the 
10k pot.
