[TenTec] Inrad 2.8K mod

Hi all,

I have an Omni VI, not a plus model. It only has provision for one 
narrow filter in the 9 MHz IF. Mine happens to have the 500 Hz option 
filter in that space. The standard 2.4 kHz filter in the 9 MHz IF is 
ALWAYS in the signal path for both transmit and receive. The narrow 
option filter is cascaded with the 2.4 kHz filter, when it is selected, 
for receive, and is NEVER in the transmit signal path. So regardless of 
the narrow option filter, the 2.4 kHz filter in the 9 MHz IF is what 
limits transmit bandwidth in SSB. If I were to change this filter for a 
wider one, my SSB transmit bandwidth would then be greater, and not 
changeable from any front panel control on the OmniVI. Would this be the 
same with an Omni + , or are the narrow option filters ever in the 
transmit signal path?

Thanks, DE N6KB
