Furthest reception from your tuner and how?

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.

Bio....Not sure about your response there, don't ask for help, then argue with people who try and give it .
If you check the website I mentioned not only will you find info about tuners, but several links about antennas and FM reception.
There is also an FM tuner group, which if you went there you would surely find your answers. This makes a lot more sense than going round and round on this forum.
Arrrrggggggghhhh!!!!!!!!!!!!!

Arrrrggggggghhhh!!!!!! What is this, a pirate thing? I once read that the Sansui Tu-X1 could pull signals in from Mars, but maybe that was on AM.

I just hate fmtunerinfo; "if it's not Kenwood, it's crap" seems to be their motto. Plus, the problem with modding tuners these days like on fmtunerinfo is that as HD radio is encroaching on the low-rez bands, it's getting harder to do a good mod without capturing all that digital hash that's not decoded in the lo-rez spectrum.

How tall are most towers to earth curvature? (i.e. - what's the natural parallax v. tower height?) is hardly argumentative. I know it's further than 80-90 miles which makes me wonder about "signal sleuth"-type boosting of signals to signal fade ratios. Not knowing is fine; I just don't want to get in to "tuner shootout" territory. Being 200 some odd miles from a source means it won't work; that's obviously too far, if it's about Earth parallax, but I wonder if 120 miles or so might work in the right circumstances.

Also: not a pirate thing.

Use a big directional rotatable antenna had occured to me. Does anyone know anything about station signal power and how it relates to tuner gangs, spec's, quieting, how the tuner actually goes about acquiring the signal?

Nobody's actually answered my question:

What's the most distant signal you've acquired and how?

Bio,

I think you are going a tad overboard with the criticism of the fmtunerinfo site. They don't all just like Kenwood. There is one guy, I believe named Jim Rivers, who evaluated a variety of tuners in his own personal system and he happened to think that the Kenwood L-02T was the best. If you go into the website and scroll down to the bottom of the page and click the FM Tuner forum, you can ask this same question and I'm sure you'll get a slew of reasonable answers. The FM forum members consist of a lot of FM techs who know their stuff. Most of these guys aren't audiophiles, so to speak, but they know their tunas and I'm sure would answer all your questions with informative answers. I was kidding about the pirate thing.
