[Scan-DC] Multiple Tornadoes, Collapse, general alarm Chas. Cty. MD 19:15

       That explains it.  In my opinion, that is not an efficient or
effective method of communications especially during emergency situations as
I have heard the dispatcher frequently limit transmissions from/to a
specific mobile unit.  Probably the other mobiles cannot hear each other
calling the dispatcher and  QRM the frequency.  I think their county EOC in
"lessons learned" needs to rethink that communication plan.
