Bv this time practically every radiofan has been able lo pick up some
far-distant broadcasting station on
his receiver during the evening. Thisfact is evidenced by the amount ofgood-natured boasting that is goingon whenever a number of fans gathertogether. Each praises the wonderfulqualities of his own particular set andboasts about the distance that has
b^en covered with It.Very few of these fans realize, how¬
ever. that their receivers are not atall responsible for this, and neitherdo they know that at various timesduring the evening they pick up sta¬tions at still greater distances. Thelatter are the cases of the wirelesstelegraph stations sending in dots anddashes, which occasionally cover un¬believable distances at night.Many of the fans are Just beginning
to realize that it is only in the eve¬
ning. after darkness has set in. thatthey get these unusual results. Nomatter how often they listen in dur¬ing the day they will never hear any-thins from beyond the normal rangeof their receiving set.
Radi«*» (ireatfur Mystery.Back of this fact there lies one of
. the most perplexing mysteries of thewireless communication art. It isa mystery that has not been solveddespite the twenty years of experi¬mentation and research that followedupon the discovery that wireless sig¬nals could be heard further at nightthan they i-ould during the day.A number of ingenious th^jries
have been advanced to explain thephenomenon, but none of these is sat¬isfying. since apparently there is no

rule or reason governing the direc¬tion or distance over which the elec-
tro-magnetic waves travel beyondtheir normal range.It is in order to place the research1
work regarding the propaganda of
energy upon a scientific basis thatthe International Conference on Ra¬
dio Communications has commenceda series of daily test signals which
are rapidly being extended to ev%rypart of the world. The general plangoverning the conference scheme was
developed at meetings held in Parisduring the months of June, July andAugust of last year.
Real Lanrn Yet Unknown.No real scientific statement of the
law governing the propagation ofenergy has yet been established, andthe scientists are still groping in thisrespect. In order, therefore, to solvethe various problems connected withthe radiation of energy through space,a series of scientific signals have beendevised and are gradually being putinto effcct at the big. high-poweredwireless stations These are trans¬mitted under the direction of theUnion Radio Scientifioi-.e Internation¬ale and in every case are precededwith the code signal "URSI."

WJZ to BroadciiNt Organ RecitalsRegularly.
Through the courtesy of the Es-tey Organ Company, the Radio Cor¬poration Westlnghouse station.WJZ, Newark. N. J., has arrangedto broadcast organ recitals at leasttwice a week during the comingwinter^The organ, because of its extreme
purity of tone and great versatil¬ity, has always been the most pop¬ular of musical instruments, andthe radio audience has voiced itsapproval of the recitals now beingbroadcasted by Several of the largerstations. Unfortunately, however,the average organ is not well adapt¬ed f<»r radio purposes. For bothstructural and artistic reasons, itis installed in several different sec¬tions; and though the player canproduce beautiful effects for hisimnied'aie audience by the appro¬priate use of these different sec-

In* range. The average owner of
a radio set believes that the ator-
age battery la properly placed in
the plrcult if the vacuum tube Is
brilliant.This is not true, for It Is ex¬
tremely Important that the posi¬tive and negative terminals beJoined to deflnlte points In the cir¬cuit If maximum efficiency Is tobe obtained. There are several hun¬dred radio receiving hook-ups, butall are based on a few fundamentalprinciples which must be adheredto in wiring th» apparatus. Vac¬uum tube circuits have one pointIn the wiring known aa the com¬mon center or common lead, as
shown in Fig. 1. At this commoncenter three" different circuits Join,and it is essential that the con¬
nections at the Junction point becorrect.A single vacuum tube detector
set conslats of three different sec-
tlons or circuits, the filameat cir-cult, the grid circuit and the platecircuit. The filament circuit ex-
tends from the positive aide ofthe storage battery through thefilament and "A" battery rheostatback to the negative terminal ofthe storage battery. This is thecircuit which lights the filament.heating It sfnd causing necatlveelectrons to be emitted. The gridcircuit consists of the secondaryof the vario-coupier or tuner, one
I side of which leads to the grid andthe other to one side of the flla-ment. The grid circuit acta as thecontrol of the tube.
CLUBS TO AID AUTOTOURISTS BY RADIORoad Travel Information to
Be Broadcasted, IsPlan.
Aujtobomile clubs in the futurewill become center* ©f advice to
traveling: motorists. They are suchaids now. but the future will see
them sending out advice as to roadsand directions while motorists are
V speeding: along the highways. Itwill be done by radio.Some time ago there came a sug¬
gestion from an automobile inventorconcerning this form of help. Hehad designed an instrument for theautomobile by which the drivercould keep on the right track inwhatever town he wanted to reachby means of a method of radio sig-naling Wires strung along theroads would carry the signals.which could be caught by the in-strument on the dashboard whilethe car traveled ahead.This is only a crude beginning to
what automobile manufacturerseventually "expect to install in theircars. A radio receiving set. com¬
pactly set on the right side belowthe dash, could be made to carryon conversation with the nearestautomobile club. From the autoclub, in this way. the driver couldlearn the way to his destination orhe colud get aid in the event of a
j breakdown.In such cases the rad io will be su¬
preme. The telephone cannot reachinto the out-of-the-way places fromwhich a person can flash his call forhelp by wireless.
