When using an autopatch you are basically allowing someone who is
unlicensed onto the repeater. What responsiblity does the user of the
radio serve? And is there anything keeping an autopatch from allowing
someone to call INTO it and reach someone on amateur radio (aside from
configuration at the repeater site?).

Now, what if someone unlicesed uses an autopatch to call a licensed ham
who IDs?

I'm just curious here as I'm new to the hobby.
