[TenTec] Omni VII Digital

[Gary - AB9M]

One of the most common difficulties is proper connection of the 
communications physical layer and its levels. So remember the audio out (pin 
4 of the OMNI-VII cable will run to line in (or possibly mic in) of the 
sound card.  The Sound card line out (or headset/spkr out) will go to  line 
in (pin 1 of the OMNI-VII).  The digital application set up tab for PTT 
should allow you to choose a physical serial port (the same one used for CAT 
control may be selected) with the PTT either by RTS+DTR or XCVR CTRL App. If 
FSK doesn’t work, try AFSK. If you do not have a physical serial port on 
your computer, use a good USB to serial adapter - TenTec sells one that 
works.

One problem that I had was with pre-made cables which instead of turning 
over audio transmit and receive from end to end, were actually wired 
straight through, or panel connections labeled line out when it was actually 
line in. An Ohm meter is your friend when working with the physical layer of 
the OSI Model.

It should not be difficult.  If using the TenTec provided cable (From
the Manual):

WHITE = pin 1, line level audio input.
YELLOW = pin 4, line level audio output.
RED = pin 5, FSK.
BLACK = pin 3, push to talk
Ground from the 46176 cable is connected to pin 2.

Have you verified the cable is correct?  It also sounds like you may
be connecting Pin 1 to the speaker output.  Not knowing what is inside
the Omni VII, I wonder if you provided it with too much voltage on
that pin at damaged the input circuit there.
