And the answer is: After changing your squelch value, you need to
press the CALL button to exit the soft-mods mode and save the changed
values. It took a call to Yaesu Tech support, but everything is back
to normal (and hopefully slightly better) now.
I'd still be interested in knowing how to set a particular value,
rather than flipping through the apparently random values, but in any
case, things are working much better now. Now I'll see if I can get
that mod description updated! Catch you on the air for Field Day '97!

}
} EXECUTIVE SUMMARY: I've screwed up my squelch threshold, and "reset to
} factory" and cloning from a working FT-51R do NOT reset this value. I
} need assistance in resetting (and saving) the "SQL TH" soft-mod
} setting. Details follow. All help cheerfully accepted!
...
} Anyhow, I put my FT-51R into "soft-mod" mode (for details on this mode,
} see URL http://www.qrz.com/mods/ft51.txt) by holding down the VOL-UP,
} VOL-DOWN and CALL buttons while powering on, and went to the fifth
} option "SQL TH", which was set to 83. I tried to lower it to match my
} other FT-51R (since this radio was suffering from my inter-mod
} interference, and I needed to really crank up the squelch to stop it,
} while my original FT-51R worked like a champ).
}
} However, I now seem to have the SQL TH set to "1" (I believe it's a
} 2-digit hex value, so somewhere around 80 should be "midpoint").
} Anyhow, I now have the radio totally deaf on the right VFO. If I open
} the squelch all the way, or push the Monitor switch, it's hearing fine,
} but otherwise there's no sign of reception (no LED, no S-meter bars).
