I was wondering what's an accurate estimate for scanner sensitivity?
I've got a Uniden BC180, and the owner's manual doesn't list that
information. I was wondering what a good value would be to use in
order to do some path loss calculations. I've heard 1.0 uv is a good
conservative estimate. Is this too low?


The 1 uv is fine for the calculations. You may even be able to go as low as
..5 uv . The lower the number the more sensitive the receiver . Not sure
what you mean about the margin to make out audio. For FM singnals .5 uv
should give you good audio with a trace of noise and at 1 uv it should be
almost full quietning (for FM that is all the hissing noise should dissapear
out of the audio ) .
