rxfax isn't sensitive to noise at all. At a gain of 12 you've caused 
overloading and distortion, and the signal cannot be decoded. Many 
people seem to be nearly deaf. They run systems at massive gain with 
awful distortion, and seem content until they find something like a 
modem or DTMF detection doesn't work too well.
