Four Methods by Which H. Armstrong Obtained Regeneato

 Denson's set is the home made vari-
 able condenser, which is very un-
 usual.
 The Radio Broadcasting News ad-
 vises that MT. H. ". Arlin, one of the announcers at K. D. K. A., the East Pittsburg radio telephone broadcast
 ing station of the Westinghouse
 Electric and Manufacturing company, recently had his voice returned to him by parcel post.
 On April 9th, Mir. Arlin was on duty announcing at K. D. K A. and the
 same evening W. E. Weaver of He's
 perler. Ontario. several hundred miles
 north of East Pittsburg,. was listen
 ing In on his radio receiver. Struck
 by a happy thought he wheeled a
 dictaphone in front of his loud speak
 CT and registered part of the concert on the record.
 He then sent this record to the
 radio department with an invitation to listen in and see how K. D. K. A.
 is received in Ontario.
 MT. Arlin was perhaps the most
 interested listener for, In addition to hearing the program sent out April
 5th, his voice registered accurately and clearly each announcement. 
 We are in receipt of letters, from 1 Age Herald readers, asking us how to make the sets such as we are con-
 structing and giving away each Sat-
 urday. We are, today, giving a com- plete list of material, together with
 the cost of each item, and complete
 instructions for building the set and
 erecting the aerial.
 The amateurs of the world have
 played a large part in bringing wire less to it's present perfection. It was the cooperation of these amateurs, in organizing clubs, publishing results of their experiments which. many times, gave the real inventors a basis to work on by comparing reports from these various amateurs In the early stages of wireless.
 The one thing, at this time, which is holding back the development of radio Is static, or atmospheric dis turbances. These disturbances are most noticeable at this session of the year. It Is discouraging to try to hear a radio concert with static con stantly breaking in.
 We believe that this apparently up- conquerable pest can be minimtzed If not entirely controlled if We anna teurs will determine to assist. Let all amateurs get together in an effort to rid ourselves of this Q. R. M. There is a chance for all of you to help. From a recent suggestion from K. D. K. A. we believe this plan will be of assistance. Let each amateur. on
 every unusual night, keep an accurate record. Take note of the weather.
 the temperature, then carefully note
 the way static hammers on the dia- hro af ut tions heard and the characteristics
 of these signals.
 If great many amateurs carefully note these conditions it surely seems probable that, before a great while,
 some basis may be found which will lead to the elimination of this now apparently unavoidable disturbance. The following letters have been recently received by w s. Y. (The Alabama Power company broadcast Ing station):
