The following is from a 1919 report regarding the U. S. Naval Radio Station, Russian Island, Vladivostok, (Call sign NPH):

Located on Russian Island, Siberia (Vladivostok). Equipped with a 60 kw arc set, and a 12 kw arc set. At the present time no permanent wave lengths have been assigned.

Radio Communication: Tests are being made to establish schedules for this station. At the present time communication is effective with Peking, Cavite, Guam and with ships within range of the station. Can communicate with St. Paul and Cordova, Alaska. Signals are very weak from those stations, but it is expected to establish effective communications in the near future.

Recommendations have been made to lay a cable from the station to Vladivostok, a distance of about fifteen miles, for both telephone and telegraph service. It is expected that this cable will be laid by winter (1919). The Vladivostok end will be at the headquarters of the American Expeditionary Forces, with a loop to a U. S. ship in port. Telephone communications may be had at the Russian Island Red Cross Hospital, about one mile from the station, which connects to Vladivostok by cable.

Comment: This station will probably handle commercial traffic as well as Government traffic. It is of military value in furnishing communication to and from the American Expeditionary Forces in Siberia, and for communicating with vessels of the Fleet in Chinese and Japanese waters.

This station was taken over from the Russian Government, and was equipped with apparatus furnished by the Navy Yard, Mare Island, and equipment taken from the Heeia Point Station, Honolulu and was commissioned about 30 May 1919.
