According to this article, Ortovox beacons are often out of spec FROM THE FACTORY at operating temperatures. Here's an article translated from "Snow and Avalanches" #95, September 2001:

What this means is that other beacons will have a hard time detecting yours.
I've also heard (though ) that Ortovoxes drift in frequency over time, and must be recalibrated every few years. If this is also true, I'd be even more worried.
