Someone not interested in SSB operation could have put a 1.8 kHz filter
in for the "wide" default 9 MHz filter. (I am guessing the Omni V filter
selection scheme is very similar to the Omni VI, if I'm wrong about that
point then I could be wrong about this whole message) Check out the
stock number on the filter and see what you've got. If it was an Omni
VI, it should be a 48058, maybe the same for an Omni V. If it is a
48037, it is too narrow for "nice" sounding SSB. If that were the case,
it would be in the SSB transmit path too. What kind of TX audio reports
do you get?
