the circuit in a manner similar to the 

 ordinary detector. 



The Federal Company operates sev- 

 eral commercial stations on the Pacific 

 coast, the most prominent one being the 

 "KSS," South San Francisco, Cal., sta- 

 tion, and a similar station located at 

 Heeia Point, Honolulu, Hawaii. The 

 San Francisco station operates on a wave 

 length of 7000 meters and actually con- 

 sumes from 50 to 60 K. W. of direct 

 current energy. The corresponding sta- 

 tion at Honolulu often operates on a 

 longer wave length sometimes at 11,000 

 meters and is particularly effective. 

 Commercial correspondence is carried 

 on between these two stations with a fair 

 degree of accuracy. An interesting fea- 

 ture in connection with the South San 

 Francisco station is that the use of a fan 

 aerial has been abandoned and a large 

 single cable substituted for it. 



Another long distance radio circuit in 

 daily use is that employing the Gold- 

 schmidt system between Tuckerton, N. J. 

 (WGG) and Eilvese, Germany (OUT).

These stations employ the Goldschmidt 

 high-frequency alternator, which is a 

 generator giving a very high frequency 

 at a low initial speed. The alternator 

 at Tuckerton is of about 70 K. W. capac- 

 ity and operates at a frequency of about 

 50,000 cycles. The station at Eilvese is 

 said to employ an alternator of 150 K. W. 

 capacity at a similar frequency. 



Immediately after the outbreak of the 

 European war the Tuckerton station was 

 taken over by the United States 

 Government and operated on a com- 

 mercial basis in connection with the 

 corresponding station at Eilvese. 

 The staff at the station at pres- 

 ent consists of ten operators, in charge 

 of a naval lieutenant. Commercial busi- 

 ness is accepted for points in Germany, 

 subject to a delay, at a rate of 50 cents 

 per word. Since the opening of this 

 service the Tuckerton station has been 

 congested with traffic and, owing to its 

 limited facilities for handling the same, 

 has often fallen several days behind. 



During the most favorable months of 

 the year, these two stations were able to 

 carry on correspondence throughout the 

 twenty-four hours of the day, but only
