Special radio service
Special service (also: "special radiocommunication service ") is – according to "Article 1.60" of the International Telecommunication Union's (ITU) Radio Regulations (RR) – defined as ""A radiocommunication service, not otherwise defined in this Section (ITU, RR, Section III – Radio services), carried on exclusively for specific needs of general utility, and not open to public correspondence"." However, the meaning of "public correspondence" is – according to the "International Telecommunication Convention" – defined as ""Any telecommunication which the offices and radio stations must, by reason of their being at the disposal of the public, accept for transmission"."
