SAT and K&C

[Farrell]

Every once in a while I would get a bum number with my SAT - one that just made no sense. My suggestion is throw that number out, insert a reasonable number, and see how the tuning sounds. Then add or subtract DOB as needed.

I don't know what it means, but I have certainly seen such readings.

SAT and K&CHi Dave:
I too, have seen an occasional negative FAC number, and I also don't know what it means.  I'd be interested in knowing.  FWIW, on a vertical, in small print, I write the FAC numbers on the hammer moldings or on the sides of the hammers if its a nice new piano, and on grands, I record the numbers to the right of the tuning pins on the plate with a fine point marker pen.  The music desk covers these small numerals when in place, and it eliminates measuring the numbers next time I come to tune.  They change ever so slightly, or not at all on the same piano.  Will look for you all in Chicago.......Mike Kurta  ----- Original Message -----

  I tunes a brand new Kohler and Campbell KIG-47 today. Aside from all the damper problems I was struck by one thing. When doing the FAC on my SAT III (too many initials I know), the F reading came out -2.2 cents. I was expecting maybe +18. First time I've seen a negative reading. I did the pitch raise (25 c) with that calculated tuning and then did a pickier pass by ear and it came out fine. But I was curious if anyone else gets negative inharmonicity readings on cheap pianos and what it might mean.....
