Wow - yes that would be nice - I think the thing I like the most about 
the Omni so far is the ability to pull out the weak stations just a few 
Hz away from someone running the legal limit - really nice.

Any thoughts about the 250Hz filter attenuation I'm experiencing 
(detailed in my previous message on this thread)?  Is this normal?  It 
seems like the signal truly is weaker with the 250Hz filter in place vs. 
the 500Hz filter - testing this using MixW's waterfall does show a 
darker blue color with the 250Hz filter instead of the 500Hz filter. 

Thanks,
Jason
