An Interview with the Inventor of the Crystaloi Detector
Hiram Percy Maxim and Clarence D. Tuska (editors)
This article appeared in the March 1916 issue of QST

 The writer, hearing the wonderful 5,000 mile record made on the Crystaloi Detector, decided to see Mr. Turney and interview him for “QST.”

 One day last month, the writer found Mr. Turney in his laboratory and asked him for information concerning the use and theory of his new Detector. The publishers of “QST” take great pleasure in presenting the results of this interview.

 First, Mr. Turney explained that his Crystaloi Detector was composed of a finely divided alloy, a great many particles of which are brought into contact with a highly sensitive mineral and for this reason, innumerable sensitive spots can he found with no more adjustment than turning a little thumb screw. The Crystaloi has a great advantage over other Detectors inasmuch as there are several fine, light metal points in contact with a sensitive mineral instead of the single point which most Detectors have. The Detector is so compactly made that it cannot get out of adjustment and it never loses it’s sensitiveness. Further advantages lie in the fact that there is no cost of operation;—the Crystaloi requires no battery or potentiometer and is ever ready to serve under all conditions.

 “The latest record made by a Crystaloi,” said Mr. Turney, “is 5,000 miles. Mr. R. J. Rohey, of Richmond, Va., heard a station at Lahaina, Hawaiian Islands. Mr. Robey heard the station four different times. We have great hopes for the Crystaloi.”

 “Are there many in use?” asked the interviewer.

 “We have sold 10,000 Crystaloi’s all of which have given satisfaction, and have seen hard service. About 600 are in commercial use, and the operators are more than satisfied. They all get excellent results.”

 Then the writer asked Mr. Turney if he had any new improvements in the Radio field. The reply was that several new instruments were being designed for amateur use and a catalog of the same was being prepared.
