Abstract	A discussion is given of all the methods of monitoring the variations in the radiated high-frequency energy which occur in the operation of short-wave transmitters which have been used in the five years' experience of the great Nauen radio station of the "Transradio A.G." Berlin, for overseas wireless communication. The monitoring apparatus is in part located at each transmitter or transmitter group and in part centrally located. Experience has shown that the monitorng of the keying, the modulation (wave-form and degree of modulation), the frequency of the carrier waves, side bands, and any adjacent waves which may possibly be present at a large short-wave transmission station where the separate short-wave transmitters are located in separate buildings within a radius of 1 to 2 km, is most advantageously effected by being centralized, whereby only one or two attendants are needed.
