[TenTec] OMNI 6+

[Bob McGraw - K4TAX]

Since the Omni VI Plus has connections on the rear panel for Audio IN  and 
Audio OUT,  I strongly suggest using the RCA connectors on the rear panel 
for the required audio signals to and from the RigBlaster.  To this end, I 
also suggest putting a 1 k ohm resistor from the Audio IN center pin to 
ground at the RCA connector on the rear.  There is a 10K series resistor 
internal to the radio.  This 1 k ohm resistor in conjunction with the 
internal 10K R provides the proper load for the device and does allow 
attenuation of the audio signal to better suit the input audio requirements. 
This assures a much better Signal to Noise ratio of the transmitted signal.

When using the Audio IN on the rear, it is important to disconnect the MIC 
from the front panel.  This assures that only the data signal is being 
transmitted and that "room noises" picked up by the mike do not corrupt or 
be transmitted with the data signal.

There is a PTT command input on a RCA connector on the rear or one can 
choose to simply use VOX with a very short hang time to handle the RX/TX 
switching.

My general rule.........if it isn't a microphone, don't connect it to the 
front panel MIC connector.  That's why the rear panel connectors are present 
and these are better suited for audio and command levels accordingly.
