The wheel seems to be coming full circle: plain language is gaining
popularity over 10-codes in emergency communciations. The problem is
that too many local 10-code dialects have developed over the years.
They can cause misunderstandings when multiple agencies work together
in a major incident.

In my area of California the sheriff departments use 10-codes but the
fire departments don't. I have no idea how long this state of affairs
has prevailed, since I only got into the scanning hobby last summer.
