I just downloaded and ran the AO-27 scheduler program and updated the 
epoch.txt and topr.txt files as instructed. I compared the text files with 
the ones currently on the AO-27 website and verified that they are correct. 
For some reason, the times generated by the program differ from the times on 
the AO-27 web site by 11 min 36 sec.
What am I doing wrong?

AO-27 is on a timer and is usually only active on ascending passes about the 
time it crosses 30 degrees North latitude. There is a program that will 
predict when it is in analog repeater mode and it can be downloaded at 
When you first run the program you need to update the files(TOPR and EPOCH) 
instructions are on the page, simple as pressing CTRL+U
