In other words, could it be a patch.
No - not a patch.
Its a means to bring various individuals into a temporary talk group for a special
or emergency purpose. For example you could have 8 people with radios on a
trunk system but they all could be on a different talk group and they are needed
in a extremely short amount of time(like a search and resque team). There radios
are pre-programmed with this Dynamic Regroup feature and their radios can all be
brought automagicly to a temporary talk group in a quick fashion with nothing being
done by each of the individuals - it is only the dispatcher that needs initiate this from
a console. However - it has some limitations such as - each radio of course must be
powered on and monitoring the system CC. If an individuals radio is keyed up and in
transmit at the time the dispatcher initiates this there is a lag time and this persons
individual ID must be retried if the first attempt to regroup them does not take place.
Its not perfect but it works well most of the time. After the group is done with there
conversation each radio is released from the Dynamic Regroup and it returns to the
talk group the channel selector is set to. I think that is how it works for the most part.
