I posted this in the power boating forum, but it seems impportant to post here, as well:
Just ran across this today.
Obviously (most) everyone knows about the upcoming switch to digital TV signals next month, but I'd never heard that EPIRB signals must go digital, as well (I assume the switch-overs are related...but even if not, this still seems critical
I'm anything but an expert in this kind of thing (that's why I didn't try to summarize any of the article)...perhaps others who know more can help explain it better. I haven't looked at my handheld unit yet, but I imagine the specifications decal on it will say what kind of signal it transmits -- to know if it's still usable (and legal to use).
In any case, it seems only wise to check your EPIRB to make sure it's still going to do what you bought it for.
