[TenTec] Omni VII Digital

[K8JHR]

Do you have a little microphone preamplifier and a dynamic (performance 
type) microphone you can plug into the Line-In input on the rear panel 
octopus cable, to determine if that works as a microphone input on 
sideband mode?  That should give a good indication whether the Line-in 
input is working correctly.   A little microphone preamplifier, like the 
M-Audio AudioBuddy will drive the transceiver in sideband mode with 
moderate output levels on both the preamplifier and about 30-40% drive 
level on the Omni VII Line-in input – and provide a rough equivalence to 
what the microphone input on the front panel will give you using a a 
similar microphone at about 40-50% MIC Gain setting.

This would test your line-in circuit independently from the digital mode 
you are working with.  Just remember to switch from MIC to LINE or BOTH 
when doing this.
