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 http://sites.google.com/site/ao27satellitescheduler/ 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
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?

Hi Chuck!
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?
What you see in the program is OK. The AO-27 web site is off. It seems to happen like that 2 to 4 weeks after the AO-27 schedule is updated. Go with what you see in the program.
You can also look at your tracking program and compare it to the output from the AO-27 program and web site. You'll probably see that the web site shows the satellite turning on near the end of the pass, or after LOS for you.
