I think the differences are with how we decode the tones. I am using an app for my phone called "Radio ID". Seems to work pretty good. After reading some of the feedback on the app it looks like it only uses a "Quick Call II" table and does not look at other ones. So it is giving me the closest match. I now have a 396XLT and will try decoding with that and see what I come up with. Either way we are close and the information above is a GREAT start to updating the list. I will keep trying and let you know.
Thanks,
Dave
