Hi Clark....
I have the Omni Vi, so my comments aimed there...

In a message dated 96-03-27 01:39:04 EST, you write:

Because the Omni VI is designed for the contestor/dx crowd, narrow skirts and
adjacent signal rejection in heavy qrm are the intent.. limited audio
response is the trade off for the steep, narrow skirts... I doubt that this
is adjustable in any fashion... The width and shape of the audio skirts are
set by the crystal filters which are specified by the designer....slight
adjustment of the PBT gives acceptable _contest_ audio to my ear...

Hmmm... I haven't noticed this... it gets much quieter because you have
sliced off about 1.7 kc of noise and clatter when you hit the narrow
button... but I do not notice any decrease in the audio volume of the cw sig
if it is centered in the filter... have you changed the side tone from the

I use the menu to turn the amplifier relay off for 'quiet' qsk.... but, I
also use headphones for this...
