Furthest reception from your tuner and how?


I am moving to a remote location - about 4 hours from San Francisco and 6 hours from Portland. There is some radio, but... I'm curious. A few questions for you tuner guru guys:

What equipment do you use?
Modded or stock?
How many filter and gangs, antennas, sleuths, etc.?
What's the most remote signal you have been able to pull?
How has it sounded?
Any thoughts on things you would try if given the opportunity?
biomimetic
A hi gain antenna is the answer if you`re in the boonies. If the stations are scattered, add a rotor.
I know it's all relative, but I'm looking for someone to answer my question about earth coverage distances and gain sensitivity. Does anyone know the formula for FM/Earth coverage based on parallax, and antenna height? Or where I might find it? In terms of absolute distances?
Arrrrggggggghhhh... obviously someone who missed my post in "the best tuner" thread...
I don't remember the formulas for this stuff but as an ex-chief engineer at a radio and TV station I can tell you that if you are more than 60 or 70 miles you aren't going to pull in much. With a high gain antenna up on your roof you'll be be lucky to recv station 80 to 90 miles. As stated above, FM is transmitted "line of sight" and the curvature of the earth is the limiting factor. While some tuners are more sensitive than others, it won't help at the distance you seem to be talking about. Sorry.
