298 <strong>Radio</strong> <strong>Broadcast</strong>after trying several other positions,it wasdecided to place the horns on the balconydirectly in front of the specially constructedbooth which housed the receiving and amplifyingapparatus.It is interesting to note thatall the horns had to be placed together becauseany separation by placing horns at variouspoints about the hall produced out of phaserelationship and distortion. As it was, onlyfive horns could be used, since the sixth faced awall and produced a decided re-echo whichinterfered with the speech to amarked degree.The receiving and amplifying apparatusused, consisted of the smallantenna described before, a frequencytrap consisting of a coil and variablecondenser, a tuned circuit, three stagesof radio-frequency amplification, asuper-heterodyne receiver with one initialstage of radio-frequency amplification, andthree stages of intermediate-frequency amplification,and the usual oscillator and twodetector tubes; one stage of audio-frequencyamplification and then six two-stage audiofrequencyamplifiers of the push-pull type,connected in series parallel, each amplifierfeeding one horn, the sixth horn being in thebooth and acting as a pilot for the operators.Some twenty-nine tubes were used in all andeach horn may be said to have had fourteentubes connected to it. Of course, the drainon the batteries was great, but four 25O-amperehour6-volt storage batteries supplied thefilaments without much trouble, while 95.dry cells connected in series successfullyhandled the plate supply. The diagram onpage 297 gives an idea of the general layout andcircuits.This system proved very successful and inspite of many sceptical opinions at the outset,sufficient volume was produced to fill the hallamply, and on the last night, the signalsWEAF fromwere reproduced with such intensitythat several of the audience on the main floorwere seen to hold their hats in humorous indicationof their approval.In 1922, when Secretary Hoover found itnecessary to call a meeting of the radio interestsbefore a special committee of hischoosing, the <strong>Radio</strong> Club was represented onthe Committee by E. H. Armstrong. Thusthe Club again as of old took an active part inthe regulation of radio by Congress. Thisspecial committee reported direct to Congresson its findings, and did much to help frame thepresent regulations.This brings the tale of the activities of the<strong>Radio</strong> Club up to the present day. It ishoped that they may continue along the samelines for many years to come and that thosepolicies which have been followed in the pastand the ideals for which the Club stands willnever be forgotten. The <strong>Radio</strong> Club of Americawas organized to propagate the art of radio telegraphyand telephony in all its branches, andtrue to this ideal it has always lentits aid to the best of its ability to allphases of the art. It originated as anamateur organization with a scientificpurpose. It fought for the continuedexistence of the amateur andhelped to educate him. It lent ahelping hand to commercial radio, byresearch and cooperation wherever it could.It gave all it had to the Government when itwas in dire need of radio personnel, and, finally,when that new element in radio cropped upthe broadcast listener itgave him muchneeded assistance. This organization belongsto no one branch of the radio art but to allbranches and therefore its duty at present mustnecessarily be one of education. Through themedium of its papers and discussions as wellas the individual efforts of its members, it mustendeavor to terminate the disastrous conflictwhich has sprung up between the original radioamateur or traffic amateur and the broadcastlistener. Both classes must be trained and assistedto become mutually beneficial to one another.The traffic man must be shown how toconstruct his transmitter so as to create minimuminterference, and the broadcast listenerhow to operate his receiver at the point ofmaximum selectivity. Neither one nor theother can or should be permitted to die out,for each has his own particular value. Thebroadcast listener class is composed of thegeneral public whose pleasure and comfort mustnot be interfered with at any cost, while thesplendid services of the traffic amateurs in theWorld War will never be forgotten and surelyentitle them to an everlasting right of existence.But, unless these two warring factions, can beeducated to cooperate and aid one another, oneof the two is doomed; and this task of educationfor the good of the radio art must now be theimportant work of the <strong>Radio</strong> Club of Americaas well as all other radio clubs throughout theUnited States.
