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 ) .

First of all, thanks for the info!

What I mean by margin is:

Transmit strength (dB) + Receiver sensitivity (dB) - path loss (dB) =
margin (dB)

If I understand what you're saying correctly, with a margin of 0 you
can still make out decent audio? I thought there'd still be too much
S/N ratio or not enough "signal" for the amp to work with in order to
get "hearable" audio at 0 margin?

Thanks again!
