I have an older (s7) Vector 975R. You can either turn Super Wideband Ka on, or turn it off and set 4 separate Ka bands on/off (33.8, 34.46, 34.7, and 35.5).
Searching thru old posts I find about an even number say to use super wideband as say use the narrow bands.
I am curious, if using the narrow band will improve sensitivity on this model like it does on some of the newer RDs.
Second question, if I do use the narrow band options, should I turn 34.46 off? I believe I read somewhere that is not used here in the states?
