often, the radio would be fully functional, but the system would be
down because the BITE was complaining about something spurious.
Someone suggested a second BITE to monitor the first.

The devil drives a fine wedge. What I do in this case is let the thing
pass with a warning to the user. What they make of it is up to them, but it
is ALWAYS best to have the machine surrender control if in doubt, because the
alternative is to ALWAYS leave a person wondering exactly where something
first appeard to go wrong, simple because it did NOT appear. A dumb human can
usually do more than a smart but broken machine.
