Hello all,

Radio Regulation terms "Primary", "Permitted" and "Secondary"

In Radio Regulations (RR) Section IV, single frequencies or bands
of frequencies are allocated to one or more services (alias users).

Primary/Permitted Service(s)
Permitted and Primary Services have equal rights, except that, in the
preparations of
frequency plans, the Primary Service, as compared with the Permitted
Service,
shall have prior choice of frequencies.

Secondary Service
Stations of Secondary Service shall not cause harmful interference to
stations of 
Permitted or Primary Service to which frequencies are already assigned or to
which
frequencies may be assigned at a later date.

Stations of Secondary Service cannot claim protection from harmful
interference from 
stations of a Primary or Permitted Service to which frequencies are already
assigned 
or may be assigned at a later date.

Stations of Secondary Service can claim protection, however, from harmful
interference from 
stations of the same or other secondary service(s) to which frequencies may
be assigned 
at a later date.
