When you use a radio you should always identify yourself to the
rest of the network (everyone else using the radios in the same
area). To do this you should start every transmission with your
radio's
callsign. Although this is a requirement of the license, the main
reason for doing this is to make sure that everyone knows who is
talking.
The callsign used must be the one registered to that radio
regardless of who is using it and what they are using it for.
You cannot generate your own callsigns, even for one-off
situations such as a radio being used as a control station. If you
require a control callsign, then you must apply to the P.M.R.
Officer. The control callsign may only be used when that radio is
acting as control. At all other times, the normal callsign must be
used.
