I ran into a gotcha someone with a better knowledge of computers would have noticed at once. Everywhere it says "L1011" I had to change it to "L1011-1." But yes, it works fine on the latest (as of this date) version of the L1011 and in P3Dv5.1 I get the callouts and and haven't crashed yet on account of bad numbers. (Not saying I haven't crashed due to old-fashioned pilot error during training flights.)
