(b) A practical knowledge of typical commercial transmitting-apparatus of a rated output power up to 500 watts, designed to emit waves of type A2 and type B respectively, together with typical crystal and simple valve regenerative receiving equipment and accessory apparatus. This will include a knowledge of the functions of the various pieces of apparatus; the tracing and clearing of faults in the apparatus; altering the frequency (wave-length); varying the transmitted power; a practical knowledge of receivers and accessory apparatus such as motor generators, storage batteries, &c., and a practical knowledge of the care and adjustment necessary to maintain the apparatus in an efficient condition.

(c) A test in commercial working, exchanging traffic as between two stations in the mobile service. This will include the preparation of messages for transmission; insertion of preambles and charges; order of transmission; transmission and reception of messages at the prescribed speed; log-keeping; and procedure signals.

(d) A knowledge of the rules and regulations applying to the exchange of radio-communications as prescribed in the General Regulations appended to the International Radio-telegraph Convention as they are interpreted in the Handbook for Wireless-telegraph Operators issued by the Postmaster-General of Great Britain; a knowledge of these regulations as they apply to mobile stations; and a knowledge of the radio-telegraph part of the Convention for the Safety of Human Life at Sea.
